Fantastic experience: Very professional environment! The doctor and staff are always ready to provide the best treatment to us. He doesn’t forces his opinions and suggestions to the patient. He explains everything thoroughly and it’s on the patient to decide. I will recommend Dr T and his staff to all. It’s worth the drive.

Fantastic experience: Great dental team ! We love Opal Ridge dental office! My husband and I long time dedicated patients of Opal Ridge dental office. Doctor and staff are very nice, professional, and truly care about their patients. Facility is clean, and comfortable. Our daughter is turned 14, and now she is a new patient of Opal Ridge dental office as well. She had her braces removed recently at the Frederick pediatric dentistry, and her side teeth on the both sides turned brownish yellow. Frederick pediatric dentistry says nothing we can do exept bleaching/or veneers. They never even told us what and why caused it. I asked them , if anything else can be tryed, before offering such a harsh treatments. They said no, thats her options, and also gave us refferal to the root canal specialist, which wants to charge us only for consultation - nonerefundable $300. I decided to show her to Dr. Thackenkary for second opinion. Turns out its enamel demineralization, very common after braces removal. He recommend prescription tooth paste to use for couple of months and see if its improve her condition. It was a huge relief, and honestly we are understand it might work or might not, but it least he is caring enough and trying least harmfull option instead of bleaching.We are highly recommend this office.

Fantastic experience: I needed an emergency x-ray with very limited time constraints and they were able to not only see me to do the x-ray, but Dr. Thackenkary was able to see me and talk to me about next steps. Felt a huge relief being able to get in so quickly and really appreciative!

It seems there is a misunderstanding on appointment availabilty.An emergency patient appointment is available within 24-48 hrs however if you are trying to schedule a specific date and time for a prophylaxis/cleaning then the availability is limited.If you read our reviews you would know that we are not a sweat shop trying to bring in multiple patients at the same time.As a single doctor practice with a dentist of 25 year experience and practicing in Frederick for the past 11 years our motto has been to provide quality care .With the current low Insurance reimbursement rates most offices tend to schedule patients every 15 minutes.I am sure you can be accomodated well in one of those pracices in the neighborhood.If you prefer more of a boutique dental practice prioritizing quality dental care then your wait would be worth it.We are however not interested in taking racist patients who comment on language skills.The receptionist you mentioned is my office manager and has been with the practice for the past 11 years and we are not going to tolerate these comments.Good Luck to you in finding a dental practice

Fantastic experience: I recently had a teeth crowning and cleaning at Opal Ridge Dental . The staff was so professional, and efficient from start to finish. Dr.T and the team explained everything clearly and made sure I was comfortable throughout the process. The crown looks natural and fits perfectly, and the cleaning left my teeth feeling fresh and healthy. The clinic is modern, clean, and uses advanced technology that made the experience smooth and stress-free. I truly appreciate their care and attention to detail. Highly recommend Opal Ridge Dental for anyone seeking quality dental care!

Gerly Oden Published on Google

Fantastic experience: I had such a wonderful experience at this dental office! As someone who’s usually terrified of dentist appointments, I was genuinely surprised by how comfortable and cared for I felt. The hygienist was absolutely amazing — she took her time with the cleaning, was gentle, and left my teeth looking and feeling like pearls! The dentist was also incredibly caring and took the time to explain everything to me in a clear, easy-to-understand way, which really helped ease my anxiety. The manager greeted me with a big, welcoming smile, which set the tone for the whole visit. Everyone was kind, professional, and made me feel at ease. I highly recommend this practice to anyone, especially if you have dental anxiety. I’m so glad I found them!

Fantastic experience: I've been to Opal Dental three times now, and all 3 times I've actually been seen by Dr Thackeray himself. At my last dentist, I'm not sure I was seen by the same dentist more than once in the last 5 years. Lauren was my Dental Tech today, and did my x-rays and cleaning. She was very friendly and personable, and I'm looking forward to having her as my Tech again! Everyone at this practice has been great so far!

Fantastic experience: I have had dental anxiety my entire life, to the point that I often put off going for way too long. When we moved to Walkersville we were looking for a new dentist and found Opal Ridge. We have been so satisfied; my anxiety has gone done so much prior to appointments. I had a lot of cleaning that needed to be done since I put cleaning off for so long. Kelsey the hygienist is so patient and calming, the administrative staff is wonderful, and Dr. T makes sure to explain everything to you. Highly recommend this team!

Fantastic experience: Staff is always nice and friendly. When I went in the first time I didn't know what to expect getting dentures, Dr. Thackenkary took the time to explain the whole process in detail. When I had 2 teeth pulled, I expected to be in pain for at least 10 days but because of the excellent care Dr. T took during the extractions I was in pain for 4 days. They are willing to work with me making payments as well. I plan to stick with Dr. T for many years.

Shariss Hite Published on Google
