Honest about what you need. And what you don’t. Patients tell us they came in braced for the upsell, the surprise bill, the office that doesn’t remember their name. They walked out with a calm recommendation, the cost discussed before the chair tipped back, and a practice they’ve come back to ever since — right across from Bank of America since 2007.
If something we did isn’t right, we want to hear about it. We stand behind our work.
Thomas Dentistry is conveniently located downtown Mercer Island right across from Bank of America. Dr. Troy Thomas opened Thomas Dentistry on Mercer Island in 2007 and lives with his family on Mercer Island.
We offer a full range of services at our Mercer Island dentist office, including routine dental checkups, cleanings, and many other procedures to keep you and your family in tip-top dental health.
We treat patients of all ages, young children, teenagers and adults. We offer family appointments and extended appointment hours throughout the week to make scheduling an appointment easy and convenient for you. We know you’re busy and constantly on the run, so our goal is to make fitting in a trip to your Mercer Island dentist as easy and convenient as possible.
Dr. Troy Thomas, Dr. Gurman Jaswal, and Dr. Ken McNabb are here to help – whether you’re looking to achieve a new smile or have dental pain and need help, we are here for you on Mercer Island serving our community.
Thomas Dentistry accepts all major forms of dental insurance and offers an optional dental membership program to help pickup where dental insurance leaves off or for patients who lack dental insurance all together. Our dental membership program is far superior in cost and benefit than most forms of dental insurance!
Dr. McNabb hails from the Kitsap Peninsula and is a proud graduate of Central Kitsap High School. He earned his B.S. in Cell and Molecular Biology from the University of Washington and later graduated from the esteemed University of Washington School of Dentistry in 2001. With 8 years in private practice, Dr. McNabb has amassed a wealth of clinical experience, making him a trusted name in dental care.
What sets Dr. McNabb apart is his holistic approach to dentistry. He treats patients of all ages, from children to adults, ensuring that each family member receives the dental care they need. He’s not just a dentist; he’s a community member actively involved in Rotary and the Chamber of Commerce in Mercer Island.
Dr. Gillian Lim earned both her undergraduate degree and Doctorate in Dental Surgery from University of Washington. She is passionate about providing high-quality dentistry with a personal touch and believes in creating lasting relationships built on trust and comfort.

“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.”

“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?!!”

“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.”

“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.”

“I love Thomas Dentistry! Tracie is my usual hygienist. It might be strange to say, but I enjoy my teeth cleanings here. They are so easy and, as far as dental work goes, as comfortable as they can be.”

“This was my first dental visit and I must say they were definitely unorganized as their X-ray machine kept freezing the images delaying my appointment and they’re not put together. The manager Carmen told me I was going to have to pay a $70 balance. Which I completely agreed on no problem. I got a bill for $140 and was never told I had a $50 co-pay on top & they don’t use silver filling so I had to pay extra for a white filling. I was not told about any of these extra charges. The manager Carmen hung up on me over the phone without trying to fully explain everything and was very rude to me. I would not recommend this dentist because they are not truthful and they want you to pay double your bill so please be careful.”

“Five stars! Great Dentist and work he does and great staff.”

“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.”

“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.”

“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.”
