Sudbury Dental Smile Center: Ronnie Du, DMD

Experiencia fantástica: Doctor Du is the best! My bottom teeth always had pockets and inflammations from time to time and I was given Gingivectomy which is a new laser treatment to prevent inflammation and this fixed my teeth problem perfectly! My teeth feel so good and I don’t need root canal and save me a fortune! Gingivectomy is invented for you if you have the same problem with me and lift is so much better without teeth inflammation! Tons of thanks to Doctor DU!!!

Experiencia fantástica: September 1, '26 I had my regular cleaning with Sam yesterday and continue to be grateful for his thorough, attentive work! And for the amiable staff. For Dr. Dai. Dr. Du provided a crown a couple months ago and her artistry with teeth amazes me at times. I don't have great teeth genes, but at least I know my teeth are in excellent care with this team. May 6, '26. After several years I continue to feel truly grateful for Dr. Du and her excellent team/staff. Today I had cleaning by Samuel with crown work by Dr. Du and assistant Ana. I'm delighted with the attentive care and as ever, impressed with the expertise and teamwork. Having teeth worked on is never fun, but having full confidence in those who are doing the work (as I do with Team Du) makes a world of difference!

Experiencia fantástica: Dr. Dai is very attentive, very thorough and thoughtful

Experiencia fantástica: Dr. Dai answered all of my questions patiently. My tooth received a perfect filling. I am very happy with the quality of the treatment.

Experiencia fantástica: Zero complaints! Everyone was super nice and everything went swimmingly

Experiencia fantástica: I visited this practice after a decade without proper dental medical care. It was such a positive experience from Kevin at front desk, my hygienist, and doctor. Jamika is the best of the best. She involved me in the process and explained everything. The patient education was so valuable. Understanding my oral health will ensure I’m more compliant. I arrived extremely anxious and left feeling relaxed. She is incredibly warm hearted, efficient, and good at what she does. Dr. Dai was great. The first doctor to address my TMJ and actually provide treatment plan options. Furthermore, Kevin provided me with an estimate for future visits and treatments. This practice was able to get me in the following week. My previous dentist offered an appointment 8 months out. Overall, this was the best experience I’ve had a a dentist. I cannot recommend them enough!

Experiencia fantástica: I highly recommend Sudbury Dental Smile Center for anyone looking for excellent, professional and warm dental care. Every single staff person who I've interacted with at Sudbury Dental has been highly professional, skillful, technically knowledgeable, kind, and very welcoming. Sudbury Dental has all the updated dental technology to ensure very skillful treatment but also great kindliness. Dr. Du has done several crowns for me and I've found her to be very gentle, even with "difficult" teeth. She also makes me feel she is looking at my long term dental health - not just trying to "make a sale" but treating me as someone whose care might stretch over many years (which I hope for too). I also want to particularly thank the staff: Jamika and assistants Booma and Ana, as well as Kevin at reception could not be more kind, friendly, talented and helpful. They are very reassuring, full of patience and good cheer. I leave Sudbury Dental every time feeling that I've gotten incredibly good care by thoroughly lovely people.

Experiencia fantástica: I have been going to this practice for several years and while I have always been grateful to have found such a wonderful dental practice , my appreciation of it continues to grow. Dr Du and the staff are very kind, gentle and respectful as well as being extremely skillful in their work. In addition, choices are given if there is more than one possible approach to a situation. There is nothing that I could wish for that they do not provide. I highly recommend them.

Experiencia fantástica: Staff (front desk, assistant and dentist) was very friendly, knowledgeable and consultative in our entire visit

Experiencia fantástica: Switched to SDSC from another very good dental office, because a family member had such a good experience here. From the first, they were kind and genuinely understanding, helping family member with extreme discomfort during dental work, bought a tool to help increase comfort and adjusted procedures as needed. Highly recommend for anyone who doesn't like going to dentist!! And for those who dont mind (like me) they use latest software/equipment to scan mouth for understanding of structure, and for cleanings (hygienist is also excellent, loves her work, and very personable) Easy to get to, good scheduling, great experience.

Experiencia fantástica: Trusted team. Sam never fails to clean gently with attention to detail. Never hurried always a pleasure. Dr Du is our long term trusted expert on all teeth issues.

Experiencia fantástica: I have seen Dr Du for almost 20 years. Always happy with the results. Today I had teeth cleaning with Jamicca ( I hope that was the spelling). She is thorough and meticulous about her work. She is the best hygienist I have ever had. Thabk you.

Experiencia fantástica: Trusted Dr Du for over twenty years!! The best!

Experiencia fantástica: Had a great experience at Sudbury Dental Smile Center. Dr. R. Du is both professional and friendly. Been a patient for over 10 years.

Experiencia fantástica: Excellent service! My favorite dental care spot. Service was great, charge was reasonable, and Kelvin the front desk always sent out the text reminding in time!

Experiencia fantástica: Great dentist! Attentive, caring and does great work. Wonderful find!

Experiencia fantástica: Kevin is always friendly and welcoming, the techs are always great and gentle (which we all appreciate). And Dr. Du is fantastic I’ve been a patient for almost 20 years!

Experiencia fantástica: (First ever visit) I’ve just visited Sudbury Dental Smile Center for the first time for a consultation and two days later, a cleaning. I decided to come here because they’re much closer to where I live but mostly because my prior dentist kept misdiagnosing me and missing the extreme pain I’ve been experiencing for 7+ months. They had also messed up on two cavity fillings that made it so I could only eat soft foods from July to November! After 5 visits for the same pain, my previous dentist still hadn’t found the issue and I was gaslit. After finally finding the issue a few weeks ago, he referred me to an oral Surgeon to take out the issue and for one partially erupted wisdom tooth with a cavity in it, it costs $1,775. I’ll get it done but with that, I must move on. Because my prior dentist kept missing the problem for each visit, I saw many other doctors to help figure me out. These are the following doctors I have visited for an unknown cavity in a wisdom tooth he could not find and diagnose. PCP x3 (ordered an MRI, chronic Sinusitis) NUERO Dr (prescribed Gabapentin for pain and rizatriptan for extreme migraines) WISDOM CONSULT (Northborough, did not find anything.. referred me to TMJ/D Specialist) TMJ/D Specialist (set up a 7K plan to have a bite guard on 24/7) ENT (ordered a CT scan and found my left side to have a deviated septum - surgery required… referred to an allergist for the chronic Sinusitis shown in the MRI from the PCP) IF my prior dentist had just helped me and found what was going on with me, I wouldn’t have had to go to all these specialists. After my wisdom tooth extraction, we won’t be able to afford what I currently ACTUALLY NEED because our money and our time was wasted. I was so nervous going to a new dentist because I am worried how bad my teeth have gotten over the years and I am worried about how much everything will cost. Imagine my prior dentist actually kept up with my teeth, I wouldn’t be having all these issues!! Sudbury Dental Smile Center has great reviews for a reason! Immediately, the whole team made me feel extremely welcome and comfortable! They answered all my questions and addressed all my concerns. They are so professional yet have a sense of humor with a light heart. I’m so thankful to have stumbled upon this wonderful dental office! (And that's why reviews are so important!) The whole team is amazing and I applaud them and think so highly of them, even after two visits. • (A year and a half later) After a full year of complex dental decisions, I can say with complete honesty that Sudbury Dental Smile Center has walked through this with me in a way that truly mattered. This wasn’t a simple filling or routine cleaning. I’ve been navigating extractions, prior graft sites, structural crown questions, sinus proximity concerns, and long-term implant planning. Every step felt heavy because these aren’t small decisions — they affect how I eat, how I feel, and my health long term. What meant the most to me was that I was never rushed. They reviewed imaging carefully, explained tooth numbers and anatomy clearly, and took my questions seriously — even when I asked the same ones more than once because I needed to understand. I was given space to think through extraction versus preservation, graft timing, and whether a crown needed structural support or a root canal. That space matters when you’re making permanent decisions about your body. They were also transparent with estimates and open to staged treatment instead of pushing an overwhelming, all-at-once plan. For someone managing prior dental trauma and complicated history, that kind of respect makes you feel safe. Dental work is vulnerable. It’s stressful. It’s expensive. It’s emotional. Having a team that listens, explains, and collaborates instead of pressures — that changes the entire experience. I’m deeply grateful for the care, patience, and professionalism they’ve shown throughout this process.

Experiencia fantástica: A fantastic dental team! My dentist Dr Ronnie Du is highly skilled and always respects my role in decisions about my career. The hygienist Mr Samuel Nyann is gentle, friendly, and does an excellent job. The office manager keeps everything running smoothly - scheduling, reminders, and insurance are all handled with care and accuracy. Truly a well-run, professional, and warm practice.

Experiencia fantástica: Ronnie continues to do a great job and still sees me in a timely manner when I have problems. Samuel is a fantastic hygienist and has helped me take better care of my teeth and gums. This is the best dental practice I have experienced as a patient.

Experiencia fantástica: Dr. Wenyong Dai is just amazing. She is very thorough and a soft spoken, caring doctor. She is very detailed and takes time to explain everything clearly. The staff is welcoming, the office is clean. You feel comfortable and well cared for throughout the appointment. Highly recommend.

Experiencia fantástica: I always have a wonderful experience when I visit Sudbury Dental. Jamika was my dental hygienist today and she was very kind, informative, helpful, and transparent. She made my experience great! I will continue to go to Sudbury Dental for all dental needs.

Experiencia fantástica: Another great cleaning experience at Sudbury Dental! This time I had to do a deep cleaning. Sam was excellent and I was in and out of there quicker than I would ever have imagined.

Experiencia positiva: The service is good. However, they need to do better to protect patients privacy. I went in and saw the computer is on. I could see everybody's appointment time and reasons for visit.

Experiencia fantástica: I have been going to this clinic over the last two years. I always had an exceptional experience , both at the customer service ( Kevin is very accommodating and understanding ) as well as the dental hygienist , Sam is really great.

Experiencia fantástica: I had a great experience at this dental office. Everyone was extremely friendly and helpful from start to finish—Kevin at the front desk, the dental assistants, and the doctor. Dr. Du explained the treatment in great detail and was very thorough, which made me feel comfortable and well informed. I would definitely recommend this dental office to anyone looking for a great dentist and a welcoming environment.

Experiencia fantástica: Dr Du has treated me over 15 years. I saw her very first with the bed gum condition and she had given a great treatment and monitor it throughout those years. Under her observation my issues were treated quickly leading to no long term issues. I strongly recommend her.

Experiencia fantástica: Dr. Du is exceptionally experienced and truly dedicated to her patients. I came to her with a very challenging dental issue, and while other dentists felt the tooth couldn’t be saved, she was willing to put in extra time and effort to explore every possible way to preserve it. Her skill, patience, and determination gave me valuable time and hope, and I’m deeply grateful for her care. She is sincere, responsible, and meticulous, and her whole team works with the same level of attention and professionalism. My experience here has been wonderful, and I highly recommend Dr. Du and her team. Truly outstanding.

Experiencia fantástica: I have been going to Dr. Du for 20 years and wouldn't think of going anywhere else! She is an artist in her dentistry. And Sam is the best hygienist I have ever had!

Experiencia fantástica: Kevin was very helpful with scheduling my appointments, and Sam did an excellent job with the cleaning. Dr. Dai handled my crown. She’s kind, patient, detail-oriented, and her skills are truly exceptional. Dr. Du was also wonderful; she took the time to explain the issues with my teeth and offered clear solutions. Overall, this is a well-run office with a great team!

Experiencia fantástica: This place is so amazing and all so friendly. Makes you feel at home when you go there. Dr. Du makes you feel at ease and takes the time to listen and really help you on the spot. I had an emergency situation and the whole experience was great.I also really love Kevin at the front desk. He is easy to talk to and is up front with finances which makes the whole experience better. He is a perfect first face to see walking in. Highly recommend

Experiencia fantástica: We have never had a better dentist over the last 46 years than Ronnie Du DMD She and her staff are highly rated professionals, see all the reviews available on the internet In our experience as well, she pays careful meticulous attention to our dental needs Before any work gets done, all of it is explained in detail and we discuss possible alternatives if any She and her staff are meticulous and gentle at the same time, in the various phases of dental treatment. Cleaning, fillings, root canals and crowns and so on are all done by her staff on hand in-office including specialists Financially the billing levels are fair and right on par with other dental offices We were not talked into any work or felt pressured but my wife Willemina needed quite a bit of dental care which of course costs money but at least is partly tax deductible. If you have Dental Insurance you can check if it is compliant with the billing coordinator The whole office is very clean, technically very well equipped while the atmosphere is like being with close family Our experience indeed made us feel like we had lucked into a branch of the family we never knew we even had! Wil and Roel Sudbury, MA

Experiencia fantástica: Dr Du has been my dentist for years. She is meticulous, thorough, and gentle, and does an amazing job with crowns. (Mine feel and look exactly like the original teeth; you'd never know they were there.) Also, a huge shout out to dental hygienist Sam, who restored my smile to pearly perfection at the latest cleaning. Highly recommend this office!

Experiencia fantástica: These folks are really good at what they do. Staff is friendly and the Doctors know their trade really well. I had pain, and I walked out without pain, went back to get things fixed, and they did quickly, and now I have no pain. Very happy with the outcome.

Experiencia fantástica: Sam is a really great doctor who makes patients feel deep clean is not that scary. I used to hate deep clean since it makes me feel uncomfortable and painful. Now I understand it’s not that hard unless you met a good doctor, who can provide you best treatment. Sudbury is a really good dental service with good ratings which deserves me to drive 50mins from Danvers MA.

Experiencia fantástica: Dr. Du is wonderful! She’s very nice, patient, and always takes the time to explain everything clearly. Her work is excellent, and I always feel comfortable and well cared for. Highly recommend her to anyone looking for a great dentist!

Experiencia fantástica: Very good experience with the receptionist, doctor, and dental hygienist. They explain things clearly and offer helpful recommendations and options. Services have been smooth, with no major dental issues.

Experiencia fantástica: I’ve been coming to this dental clinic for the past 6 years, and I couldn’t be happier with the care I’ve received. The team is consistently professional, friendly, and attentive. They always make me feel comfortable and well taken care of, whether it’s for a routine cleaning or a more involved procedure. One thing I truly appreciate is how accommodating they are with scheduling. Life happens, and whenever my schedule has gotten complicated, they’ve always worked with me to find a solution without any hassle. This isn’t a big franchise—it’s a local clinic that genuinely cares about the community and their patients. That personal touch really makes a difference. I highly recommend them to anyone looking for reliable, compassionate, and high-quality dental care.

Experiencia fantástica: Kind, skilled, and efficient staff at this impressive dental practice. Customer-focused staff is clearly committed to the success of the business and the comfort and education of its clients.

Experiencia fantástica: Great service, Kevin is so kind and helpful and Sam provides the best services to date. This is a dental visit you’ll love going to.

Experiencia fantástica: I recently visited my dentist for a cleaning and a crown, and I must say, the experience was exceptional. The level of service at this practice is truly remarkable. From the moment I walked in, I was greeted by a friendly and professional staff who made me feel at ease. The dental team worked seamlessly together, showcasing their commitment to providing quality care. What impressed me most was their dedication to patient education. Each step of the procedure was thoroughly explained, ensuring I understood the process and felt comfortable throughout. The hygienist was meticulous during the cleaning, and the dentist demonstrated a high level of skill and expertise while placing the crown. Overall, my visit was not only efficient but also enjoyable. I highly recommend this dental practice to anyone seeking a professional and compassionate team that prioritizes patient care. I am grateful for their excellent service and look forward to my next appointment. 8/19/25 Hunter I just had my teeth cleaned, and the hygienist was absolutely wonderful—skilled, knowledgeable, and so patient. She took the time to explain the proper way to floss and how to use my electric toothbrush, and even praised me for the care I have been taking with my teeth, which truly warmed my heart. I have been coming here since 2006, and the level of service only gets better with time. They employ the kindest, most genuine people, and I would not expect anything less.

Experiencia fantástica: Jamica’s fantastic! She’s the most patient, thorough hygienist I’ve ever had. Thank you Jamica!

Experiencia fantástica: Dr. Du and her team at Sudbury Dental Smile Center are wonderful, experienced, and professional.

Kevin is also very professional and fast at responding to my needs for appointments!

Experiencia fantástica: Great staff that is both kind and knowledgeable! I have been very happy with the quality of the dental work as well! I would definitely recommend to anyone looking for a new dentist!

Experiencia fantástica: My First time at this place was today. They were kind and polite. Dr.Sumin Hahm answered my questions with knowledge and gave me good input about my concerns. Mr. Kevin is cordial and quick to answer and handles my appointments with care. Mrs.Booma is patient and kind, I felt so comfortable around her, that it looked like I a met her a long time ago. I would definitely return again. (Marina)

Experiencia fantástica: Excellent dentist experience! Everyone on the team is really kind and informative and makes the process easy and seamless. I am someone who is often anxious going to the dentist, and I appreciate how sensitive and humorous the dental hygienists are which help put me at ease. Also for anyone with a busy schedule, the office hours are perfect for fitting in appointments in between work and childcare pickups! Definitely recommend!

Experiencia fantástica: Friendly service, make dental work easy and simple. Kevin at the front desk is awesome!

Experiencia fantástica: Found Sudbury Dental Group as an emergency when one of my fillings fell out and they were absolutely amazing. They got me in that day and I’ve continued to see them as my dentists. Definitely recommend to anyone needing any kind of dental care!

Experiencia fantástica: Kevin in admin is nice to work with. Sam was my dental hygienist and was very thorough yet not too powerful on my teeth. Dr Doo is great.

Experiencia fantástica: I’ve been going to Sudbury Dental Smile Center for about three years now, and I honestly can’t recommend it enough. From day one, the entire team has been incredibly kind, inviting, and professional. They always go above and beyond to make me feel comfortable, and they somehow manage to squeeze me into the schedule whenever I need to be seen, something I truly appreciate. The office itself is very clean and organized and has such a calming, welcoming atmosphere. Everyone there is helpful, accommodating, and genuinely cares about their patients. It’s rare to find a place where you feel truly taken care of, but this office delivers that every single time. I’m so grateful to have found them!

Experiencia fantástica: The staff are amazing! The dentists at Sudbury Dental Smile Center have to be some of the best I've ever had work done by. They gave me the best cleaning I've ever had. They were incredibly kind and professional, and very clear and concise when it came to Informing me on the condition of my teeth and what further procedures they recommended for ongoing health. They were incredibly quick to see me, and the procedure pricing was also very reasonable.

Experiencia fantástica: Jamica at Sudbury dental is amazing! She did such a thorough job and was so kind! 10/10

Experiencia fantástica: Absolutely love it here! I’ve been coming for years and they are always so nice and do a great job. Sam is just incredible!

Experiencia fantástica: I have been a patient of Dr Du for the past 15 years. I’ve always loved her work, she is a perfectionist! She is friendly, compassionate and very professional. Cristiane Pepper

Experiencia fantástica: Dr. Hahm conducted a molar extraction for me. During the consultation, he explained what his diagnosis is of my dental condition, and provided me options. After careful consideration, I agreed to move forward. Dr. Hahm was very thorough explaining the steps, as well as post-op care instructions. He was available to answer my questions via text while I was in recovery mode. Dr. Hahm was very responsive and thoughtful thus far into my treatment.

Experiencia fantástica: Excellent dental care and staff. I’ve been going here for an over a decade and their utmost priority is to make sure that you have the best dental health. Most importantly, they are truly great people.

Experiencia fantástica: Dr.Du is very knowledgeable and has a wonderful bedside manner. I had a crown put in and it was the best experience I’ve ever had and the results were perfect. Thank you Dr. Du!

Experiencia fantástica: We just moved to Sudbury and wanted a good local dentist. Over the past 10 years, we've been to 3–4 dental practices, and this one is by far the best. Sam, my hygienist, is amazing—thorough, patient, and caring. Kevin at the front desk is professional and friendly, making the visit smooth from the start. Dr. Dai is very patient and takes time to answer all my questions. Great experience overall. Highly recommend Sudbury Dental Smile Center!

Experiencia fantástica: Very professional and accommodating; my whole family has been going to Sudbury Dental Smile Center for years.

Experiencia fantástica: I found Sudbury Dental Smile Center on Google and had a great experience. The entire staff is professional and made me feel welcome from the moment I walked in. The receptionist (Kevin) was friendly and helpful. Sam, my dental hygienist, was amazing. He took his time with my deep cleaning, made sure everything was thoroughly done, and stayed calm and patient throughout. He even started with a bit of small talk to help me feel comfortable, which really made a difference. I could tell he genuinely cared about my oral health—he went above and beyond! Also, thank you to the team member who took pictures of my mouth—she was so patient and kind. Highly recommend this place for anyone looking for professional and caring dental care!

Experiencia fantástica: Dr. Wenyong Dai and her team are consummate professionals! They combine cutting edge dental techniques with highly personal, individual care. I don't always have a lot of time. Her team works with me to ensure I am able to complete all recommended care on a timeframe that makes sense for my schedule. They are always friendly, accommodating, and responsive. I highly recommend her practice!

Experiencia fantástica: Im always reassured by the kindness and professionalism of Dr. Du and her staff. It (almost) makes going to the dentist fun. :)

Experiencia fantástica: Dr. Du is the consummate professional. Historical fact: I did not like going to the dentist. Since CY 2011, Dr. Du has made dental visits enjoyable. I’m very happy to have found her practice so close to home. Plus the dental care Ronnie provides is the best I’ve ever had and I’m 71.

Experiencia fantástica: I couldn’t have asked for a better experience! The entire staff was incredibly friendly, welcoming, and professional from start to finish. They made me feel comfortable right away and took great care of everything. The office is clean, well-run, and efficient, and I never felt rushed. I highly recommend this place to anyone looking for a great dentist, I’ll definitely be coming back!

Experiencia fantástica: Dr. Du is fantastic! I had to have some porcelain veneers put in for my front bottom teeth and they look amazing. The color, size, everything matches up perfectly. Dr. Du is an artist, through and through. I also have my teeth cleaned here every 6 months, always with Samuel. He is the best you can find and does an extremely thorough job. Would highly recommend this office for cleaning and cosmetic work!

Experiencia fantástica: I have been with Dr Du for about 10 years. Meticulous, careful, professional. Best dentist I have ever had.

Experiencia fantástica: New dental office for both my husband and me. Having come from a family of dentists, I searched before settling on Sudbury Dental SmileCenter. Very pleased with the quality of work, the staff and atmosphere. Dr. Du is excellent and does top notch work! The hygienists, Kevin and Dr. Dai are wonderful. No complaints and highly recommend this office.

Experiencia fantástica: Worked through a scheduling conflict and Doctor took the time out of her busy morning to fit me in for a cleaning. Great customer service. Much appreciated the flexibility. Thank you.

Experiencia fantástica: Dr. Du and her team are great. They provide a comfortable and relaxed atmosphere, clearly explaining every step of the way. Their gentle touch and meticulous attention to every detail makes even the routine checkups a good experience. I highly recommend them to anyone seeking a dentist. Thank you Wayne

Experiencia fantástica: Dr Ronnie Du and Dr Dai are wonderful as is the entire smile center staff. They are all so helpful, kind and accommodating. I highly recommend this dental office.

Experiencia fantástica: been going here for more than 10 years- can always rely on them for a good job. Sam the hygienist especially is great!

Experiencia fantástica: The people here are great. Sam does an excellent job doing the cleanings. Dr Du is superb. The best overall.

Experiencia fantástica: I've been coming to Sudbury Dental Smile Center for 15 years now, and each visit was informative and professional! The front desk staff is caring and helpful and Dr. Du and her associates always do a great job with my teeth.

Experiencia fantástica: Yet another awesome review lined up for Dr Du and the team at Sudbury Dental Smile! I requested a last minute visit for a tooth situation and everyone, I mean EVERYONE accommodated me. Kevin squeezed me in between the packed schedule, Booma scrambled left and right to get a chair ready for me, Julie was super helpful juggling between patients and me, Samuel caught me by the corner of his eyes and said hi, and Dr Du spent a solid 20 minutes to fix my tooth situation. These folks respond at a moment’s notice, and I sincerely hope they get to see and understand the extent of my gratitude towards them! Here we go again with another review on the Dr Du team! Went in for my son's Invisalign assessment, ended up getting a wisdom tooth pulled out! It was inevitable, but the staff made it so chill that I ALMOST felt like I should've gotten other services, just so I can stick around and hangout longer. Kevin's at the front desk, and his chill attitude handles all the phone calls / texts. Booma was around to jokingly give me a hard time, always good to see you. There's a new staff whom's name I didn't catch, but you were very professional yet down to earth while Dr Du used those pliers to yank out my tooth. For such a thin lady, she packs a lot of muscle power that she deftly uses to extract my tooth, no need to cut my gums either. My son's Invisalign pricing was competitive, and my tooth removal wasn't much more than a tank of 93 octane. Can't beat that.

Experiencia fantástica: I have been with Dr Du for more than 20 years. I guess I owe her a good review. Ronnie, herself, is a very caring dentist. She talks very soft but gives affirmative professional advice. I believe her staff are very good too. I can still remember a few names. Kevin in the front. He is very efficient and will do extra work to try to fit my schedule. The lady before him was good too. Sam, a nice black gentleman, does a fabulous job on my cleaning. I live pretty far in the distance. The reason that I keep using this clinic for my teeth is simple. It is good!

Experiencia fantástica: Dr. Du has a lot of experience, very good professional technology, and most importantly, she has extraordinary patience. In fact, the whole office is very nice, kind and friendly. My son was afraid of injections and refused to cooperate. They tried every possible way, waited and comforted him, and completed the extraction. There was no rush to lower the standard of the extraction. The root of the tooth was intact, with little wound, and my kid recovered quickly. Thanks a lot to their team!

Experiencia fantástica: Very good, clean dental office. Ronnie is great, the office staff and hygienist are professional. I recently moved to CT and they transferred my records within 30min of me asking them. 10/10

Experiencia fantástica: This place is fantastic. I had to go in for a tooth pain/ emergency. Right from the receptionist Kevin to the Dental Assistant Bhooma to the DMD, they made you feel at home and really trying to serve your need in the quickest possible fashion. Extremely pleased and well done !!

Experiencia fantástica: Went for my regular every 6 mos. cleaning. I’m happy the way the nice guy did the cleaning (sorry i forgot to ask his name) he’s very detailed and did a great job.♥️ Thank you so much Dr.Ronnie Du and all the Sudbury Dental Smile Staff. Keep up the good work.

Experiencia fantástica: Dr. Du and her team are fantastic. I've had invisaling, 2 implant crowns, some fillings and regular cleanings that I go for. My 2 year old son and husband go here as well. I wholeheartedly recommend this place.

Experiencia fantástica: On time start , no extended waiting in the lobby. Cleaning done quickly and painless (as possible ) . Thanks and would recommend!! 9/9 review : Sam, thanks for head pillow, small gestures like this makes a difference (for people like me). Dr.Han - this is the first time someone has shown me visually how to use the oral-B electronic brushing properly. Thanks for that. Having a good tool but using it incorrectly does not provide desired results !!

Experiencia negativa: Cracked a tooth on a chicken wing and went in to see if it could be sealed or if I needed a crown. Made an apt and got a text asking if I could do an earlier apt. I declined and arrived at my booked time. The tech was wonderful, but Dr Wenyong Dai was not. In addition to being condescending with the tech, she told me the crack I had was not new and I was mistaken. She even had my hold a mirror and show the crack, which is visible to the naked eye, and she said no it was a tooth concussion. She refused to give me any treatment so I left. While I was checking out the desk staff they asked about my experience and I said bad because my tooth is cracked and the doctor won't treat me. She came out of her office to argue with me in the lobby. I finally got out of there. 2 days later I got a second opinion and the crack was confirmed and I will be getting a crown. Does she need to get her eyes checked or was I just the last client of the day in a day she wanted to leave early, which is why I got asked to move my appointment? Not sure the reason, but Dr Dai did not show any respect for me or her own staff and I am so glad I trusted my gut and had a real dentist, that is willing to work, check it out.

Experiencia fantástica: I’ve been coming here for dental work for years now and it’s always painless and easy. The waiting area is very comfortable and welcoming as well.

Experiencia fantástica: Dr. Du has a welcoming environment filled with dental professionals that are at the peak of their expertise. I have enjoyed going to her office for over 10 years. I continue because it is a place where I not only feel comfortable, despite the fact that I do not like dentists and am afraid of their equipment. They are truly interested in providing quality Care and a sense of calm in an environment that normally does not bring about such positive feelings. I will continue to go to her and be happy with my decision. Brenda

Experiencia fantástica: I could have given Dr. Ronnie Du and her staff a 10 rating but there were only 5 stars. Dr. Du and her professional staff have been my family’s dentist for the past 10 years. I can’t say enough about the genuine kindness, and excellent dental care that we have received. From the state of art digital equipment and technology, to the caring, sensitive, empathetic approach in the delivery of care. I highly recommend this practice and this group of truly professional caregivers. Nancy L,

Experiencia fantástica: Sudbury Dental Smile Office have been our dental office of choice for my wife (Yana) and I (Ted) in the past 15 years. Each time we saw Dr. Ronnie Du & her team we were met by utmost care, courtesy, and brilliant dental services. Thanks to Dr. Ronnie Du our teeth have never felt and looked better: she enabled us to have healthy, white, and straight teeth, which make us look many years younger; much better than a facelift. The office is clean, cozy, and conveniently located in Sudbury. The billing is fair and skillfully optimized to benefit from any insurance we might have. Dr. Du and her staff’s kindness and wonderful sense of humor make us feel pleased and relaxed like being with joyful friends. This office is the best dental office we have ever had in the past fifty years, and we feel blessed and grateful to have it. Therefore, we highly recommend it to our friends and neighbors.

Experiencia fantástica: I've been going to Dr. Du for two years, and she's done a wide range of amazing work on my teeth. I've had several crowns, onlays, fillings and wisdom tooth extractions, and all procedures have turned out great. In particular, her onlay work has completely transformed several teeth that were damaged many years ago, and they now look and feel as good as new. I highly recommend Dr. Du and the Sudbury Dental Smile Center!

Experiencia fantástica: Had a great experience here as a first time patient! Everyone was so friendly and welcoming. I went in for a cleaning and with a couple of questions about Invisalign. They were able to take all my scans, come up with a treatment plan, check my insurance coverage, and quote an estimate all right then! I was in and out for a cleaning and a while Invisalign plan in less than an hour. The best!
