Happy Client from Mercer Island Office

“I did not have a dentist in the Seattle area and choose Thomas Dentistry because they were close and nearby. Boy, did I strike gold! I hadn't been to the dentist in a while and I needed some work done to get clearance for a other medical procedure. They were so great in getting me set up and expediting my treatments. Everyone was very professional and friendly. I can highly recommend them for your dental work.”

“Dr. Thomas is an amazing dentist. At both his Mercer Island and Kirkland offices the staff is very warm and welcoming. Dr. Thomas has been my husband’s and my dentist for over 20 years and has done exceptional dental work. He makes his patients feel at ease with his caring, positive and fun personality. My grandchildren also see Dr. Thomas and he has an amazing way of helping them to feel comfortable and thus, cooperative. Dr. Thomas has the highest medical and ethical standards. I highly recommend seeing Dr. Thomas for any dental procedure.”

Happy Client from Kirkland Office

“Such a wonderful dentist's office! The staff is always welcoming, efficient, and they do a great job with my oral care. The other day I had a tooth brush bristle stuck in between two of my teeth and needed to come in for a minute visit. They got me in that day and were able to remove the bristle. It was such a relief! Going to the dentist can somethings be uncomfortable, but at Thomas Dentistry I always feel taken care of.”

Faith Hutcherson

Happy Client from Kirkland Office

“Really enjoyed my experience here for a teeth whitening. The Kirkland location is great; it’s close to the freeway so it’s easy to find, and there was designated parking for patients. The staff (I’m talking from front desk to assistants to the doctor) were all very friendly and extremely efficient. I was talked through what they were doing so I felt at ease the entire time.”

Madeleine Dow

Happy Client from Mercer Island Office

“Dr. Nguyen and the dental hygienists are super nice! I felt comfortable and safe—even the time I started crying when I had a panic attack before getting some cavities filled. (Sorry about that lol.) Anyways, Dr. Nguyen was very kind, gave me space to chill out, and didn’t make me feel embarrassed, even though I wouldn’t have blamed him if he did.”

“Thomas Dentistry makes going to the dentist something to look forward to.”

“Very incompetent doctor dr. Thomas is after money. Don't believe anything he is saying. Other doctors are all recent college graduates with no experience. Don't trust them. Get a second opinion or just go some place else get your teeth done.”

Root Canal Treatments

When decay or physical trauma damages a tooth in such a way that it compromises the pulp of the tooth, one way that our dentists can suggest to save your tooth is through a root canal treatment. Root canal treatment has a reputation for being a painful treatment.
