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.

“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.”

“I’vy been a patient with Dr Troy for fifteen years and have always been impressed with him and his entire staff. I am 86 years old and was hesitant to make my visit, but his whole staff used the best practices to insure the safety in the office. Unfortunately , I will be moving to California ima month or so and will have to find a new dentist , and hope that they will be as good as Dr Thomas and his staff.”

“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.”

“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?!!”

“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.”

“Dr. Thomas is great. Very friendly and takes time to address your concerns. The staff is very helpful as well.”
Vanessa Hoffman
Happy Client from Kirkland Office
“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.”
