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 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.”

“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.”
Betsy Tutland
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.”

“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!!!”
