Ronald Folse
Happy Client from Kirkland Office
“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.”
Faith Hutcherson
Happy Client from Kirkland Office
“Really enjoyed my experience here for a teeth whitening. The Kirkland location is great; it’s close to the freeway so it’s easy to find, and there was designated parking for patients. The staff (I’m talking from front desk to assistants to the doctor) were all very friendly and extremely efficient. I was talked through what they were doing so I felt at ease the entire time.”
Holly Yee
Happy Client from Kirkland Office
“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.”

“I have had a ton of dentistry done and have been to alot of dentists. These folks have it together. Just had a molder crown replaced. Quick ,completely painless and my bite is perfect 1st try. Absolutely no adjusting and then they repaired a front tooth I had broken after quickly epoxy in molder. This was the 2nd appointment to install crown and I was only in the chair 20 min. Went like clockwork and looks awsum. Thanku. Only thing better would be free haha!”

“Thomas Dentistry makes going to the dentist something to look forward to.”
Patrick Dion
Happy Client from Kirkland Office
“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.”

“Had my teeth cleaned today again by Rosie. She is an excellent Dental hygienist. Takes the time to answer all my questions and is very informative. Greatly appreciate it.”

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!”
Tyler D
Happy Client from Mercer Island Office
“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.”
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.”

“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.”
Elaina Sh
Happy Client from Kirkland Office
“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?!!”
Linda Scott
Happy Client from Kirkland Office
“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.”
Edward Estrada
Happy Client from Mercer Island Office
“Efficient and kind staff! I went through a period of dental anxiety and my transition to this office was smooth and uneventful. They have decent hours, good parking, a great playlist, and refer to good endodontists. What’s not to love? ❤️”
