About Coyne Dentistry

Dr. Nate now leads care at a practice known for fitting patients in quickly whenever pain strikes, whether that's a chipped tooth or a sudden toothache.

Coyne Dentistry is a general dental practice in Dayton that also offers Invisalign, traditional braces, and retainers. Reviews describe a practice that moves quickly when something goes wrong, fitting in chipped teeth and urgent pain the same day or next morning, and appointments themselves tend to run on time with little waiting. Multiple generations of patients mention feeling like part of the family here, with hygienists remembered by name across decades of visits. Nervous patients in particular note feeling relaxed during procedures, including deeper work like root planing.

My family and I have been their patients for 42 years with most of the same staff still working there. That in and of itself is a testimony to the Coynes' leadership and character. They are superb dentists amd truly care for their patients. Dr William Coyne called me numerous times when I was experiencing issues with a very bad abcessed tooth. They are very skilled at dentistry and you are like family to them. I highly recommend this wonderful dental practice.

Choosing a new dentist is a daunting task. My previous dentist abandoned me during my time of need with an infected tooth (as a result of a root canal he did). The folks at Coyne jumped in and did everything they could to help me, including getting me in touch with a specialist for a root canal redo. I now use them as my regular dentist and I can’t tell you how amazing they are. I really appreciate how everyone takes the time to explain things rather than rushing you in and out. I also signed up for their discount plan since I have tons of dental work that over time needs refurbished. Since I don’t have dental insurance, I have a little bit of peace of mind knowing I get free cleanings and discounts on dental work. Their office staff is also very friendly and helpful. I am very pleased to have found this office.
