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 visited Thomas Dentistry as a new patient on 9/9/21 and was impressed with their friendliness and professionalism. While there, multiple staff joined in to help resolve a personal issue, for which I was very appreciative. My husband and I will definitely schedule again with Thomas Dentistry Kirkland, and I’ll recommend them to family and friends.”

“I've looked for a dentist in the Seattle area for eight years. I'll never go anywhere else. The last year with Dr Thomas has been great. His staff is just as great. Very solid work.”

“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!!!”

Happy Client from Mercer Island Office
“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.”
Barb Patterson
Happy Client from Mercer Island Office
“I needed a dentist close to home and they are close enough for me to walk. I've been twice now and both times had a great experience. Dr. Jaswal has a wonderful chair-side manner and super sense of humor.”
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.”
