Happy Client from Mercer Island Office“I have been a patient of Dr. Thomas since he began his practice. He is thorough in his exams, and professional in his treatments. He has done root canals, implants, and crowns for me, and the results have always been very good.”
Richard Fryant
Happy Client from Kirkland Office“Best dentistry I've ever been to. The people here are thoughtful and very professional. The work I've had done has been very high quality.”
Elaina Sh
Happy Client from Kirkland Office“Went to that office last year to get a crown on implant and Dr. Thomas did the ugliest crown possible. Shape and height looked completely different from natural tooth I had in that place before. He did not even try to fix it. This year my new dentist confirmed that the crown should have been done completely different but now Im stuck with this crown for a while because it will cost a ton to re-do it since that is a dental implant crown, not just a regular crown. I guess I missed the first red flag when they said they do root canals and extractions too. Of course, why even going to roots canals specialists and oral surgeons if You can get a “buffet of services” at Dr. Thomas! Also Molly at the front desk is the rudest receptionist I ve even seen, billing office could not get the numbers right and overcharged me for about $800 then refunded but can this office be more unprofessional and thirsty for money?!!”

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.”
Patrick Dion
Happy Client from Kirkland Office“Best dentist I’ve ever been to. Not only are they prompt and quick but they walk you through your care clearly and explain the how’s and why’s. For once if feels like having an office that has a comprehensive plan for me rather than me checking a box every year. The hygienists are empowered to spend time with you and even book appointments with them right in the chair. Could not recommend more.”
Audra Saisslin

Happy Client from Kirkland Office“I have had a ton of dentistry done and have been to alot of dentists. These folks have it together. Just had a molder crown replaced. Quick ,completely painless and my bite is perfect 1st try. Absolutely no adjusting and then they repaired a front tooth I had broken after quickly epoxy in molder. This was the 2nd appointment to install crown and I was only in the chair 20 min. Went like clockwork and looks awsum. Thanku. Only thing better would be free haha!”
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.”

Happy Client from Mercer Island Office“I just started going here this year after bouncing around different dentist for years and have had a great experience each visit. I have had everything from cleaning, fillings, root canal, crown and they have all gone well. The office is nice, conveniently located and has off street parking. The entire staff is very friendly and helpful. Dr. Jaswal is excellent, takes his time not only with his work but explaining what you have going on, your options etc. Overall only good things to say about this place and definitely recommend it.”
Nicholas Smith

Peter Christian
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.”
