A note from Dr. Thomas
You should never wonder if your dentist is selling you something you don’t need. We’ll tell you what’s actually going on with your tooth, what your options are, and what you can wait on. And if something we did isn’t right, we’ll make it right.

“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.”

Happy Client from Kirkland Office
“Great experience with hygienist today. Thank you for being so kind and not judgemental. Looking forward to a long relationship with this dental office.”
Susan Slagle
Happy Client from Kirkland Office
“I just recently transferred over to Thomas Dentistry and I’ve had two appointments so far, which I have had positive experiences with. The front desk is very friendly and accommodating, and they let you know about costs up front. I’ve had two different hygienists and they both have been good and thorough. I saw Dr. Jaswal both times and he has a very calm demeanor which puts you at ease. He also has a good sense of humor. Thomas Dentistry takes the unpleasantness out of going to the dentist!”

“Great dentist! I came after Covid for my first checkup and cleaning, and ended up needing to have some childhood crowns replaced. During the process they were very thorough, even once getting a crown remade to have a perfect fit. One of those visits came in under the estimate. I appreciate the care they take in their practice. The staff are always nice and fun to talk to. Since my first series I’ve come here for over a year and have always had great experiences. Still need to floss more but the dentists and assistants are super nice about it! Also have great reminder system, and are very patient and thorough when working on insurance issues.”
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.”

“I have been a patient at Thomas dentistry for over 10 years and have always appreciated their open and friendly atmosphere, knowledgeable and helpful advice, use of new technology and methods, consistent and kind care. Dr. Thomas, Dr. Nguyen, and Dr. Jaswal have all demonstrated genuine care and interest in their patient’s lives, dental health and history, and other medical concerns. I admire their dedication to providing excellent solutions to dental problems, and patience with special issues. I would recommend this team to everyone!”

“As always Dr. McNabb did not fail to impress! We are very fortunate to have him as our dentist . But I also wanted to lift up NADIA who cleaned my teeth this time around and did such an AMAZING job. She is really good at what she does, and has such a calming and personable way about her. Highly recommend these guys!!!”
