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.”

Milo

Happy Client from Kirkland Office

“Great dentist! I came after Covid for my first checkup and cleaning, and ended up needing to have some childhood crowns replaced. During the process they were very thorough, even once getting a crown remade to have a perfect fit. One of those visits came in under the estimate. I appreciate the care they take in their practice. The staff are always nice and fun to talk to. Since my first series I’ve come here for over a year and have always had great experiences. Still need to floss more but the dentists and assistants are super nice about it! Also have great reminder system, and are very patient and thorough when working on insurance issues.”

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!”

Root Canal Treatments

When decay or physical trauma damages a tooth in such a way that it compromises the pulp of the tooth, one way that our dentists can suggest to save your tooth is through a root canal treatment. Root canal treatment has a reputation for being a painful treatment.
