Fantastic experience: My experience with the care team was great. They listened to my concerns and they explained to me really well. What the procedure needs to be I am happy with what I heard and I feel great to move forward with this company.
Fantastic experience: It was my first visit to the dentist in several years and I was extremely anxious. It started out great with the receptionist who was very kind and welcoming and was making small talk with me. Taunia was my dental hygienist and was very thorough, patient, and understanding with me. She never gave me any trouble or grief for not coming in sooner and she was very knowledgeable in all of the processes. Dr O’brien was the dentist I saw and he was very kind to me as well and again didn’t give me any judgement and is going to help me fix my smile. It was the best experience I’ve had at the dentist for a very long time!
Positive experience: Nurse was very sweet and nice. I will glad to go back in shortly

Hi, Mark. We appreciate the kind words and are glad we could provide you with a positive experience!
Fantastic experience: Dr. Reardon is so incredibly patient, compassionate, and understanding. I went to see him in Nov. 2024 in an incredible amount of pain due to long neglect of my teeth. I had begged 30+ dentists for total mouth extraction and dentures. Every single one denied me, until Dr. Reardon. He approved them and his office was so helpful with insurance and finding the best way to make it financially feasible. I got all my teeth out in Dec 2025, was seen three days post op, and was given compassionate care - the dental assistant held my hand as I went under for surgery and Dr. Reardon was gentle, kind, and thorough. My first set of dentures did not fit, so they completely redid my impressions and made a new set. I've been back for several minor adjustments and not once have I been made to feel like I'm silly, ridiculous, or overly sensitive. Dr. Reardon and his team are focused on my comfort, my ability to eat, and the beauty of my new smile, and I could never ask for a better dentist.
Fantastic experience: Wonderful staff. The crew was awesome and worked outstanding together. Most definitely recommend!
Fantastic experience: Made me feel comfortable when I was nervous at first and thorough great job.
Fantastic experience: Friendly staff, a clean environment, and professional care. Cant ask for much more.
Fantastic experience: I am almost 30 years old and still terrified of the dentist, they were extremely kind and patient with me. This was hands down the best dental experience I have had in my life.
Fantastic experience: Very caring and put me at ease during my check ups. They always listen to my concerns.
Hi, Ann. Your feedback is highly appreciated. Thank you for the review!

Fantastic experience: Dr. Reardon is a very kind, professional and skilled dentist. His staff is very helpful and I was in to see the dentist right away. Dr. Reardon is very compassionate and listened to all of my concerns. I will definitely be seeing him again.
Fantastic experience: My family and I have been seeing Dr Reardon for years. I have always been satisfied with their work and attention to detail. They are always friendly and explain everything well. I am so glad we started going to Yakton Dental.
Fantastic experience: We switched to Yankton Dental recently, but I can already tell you it's wonderful. The receptionist, Avery, is always so welcoming and inviting. We've been in twice and she remembered our names (it's the small things). We are getting services covered through insurance that we were previously told weren't covered. So far it's been an absolutely wonderful experience for my husband and I along with our girls.
Fantastic experience: Emergency took me in remove wisdom tooth and chipped tooth. Good staffs and dentists

He doesn't make you feel bad, that you didn't take really good care of your teeth, Dr. rearden is very compassionate, to your problem and doesn't expect the impossible, he works with what you've got. He does everything he can to fix it.
