“I have been a patient of Dr. Thomas since he began his practice. He is thorough in his exams, and professional in his treatments. He has done root canals, implants, and crowns for me, and the results have always been very good.”

“I have been a patient at Thomas dentistry for over 10 years and have always appreciated their open and friendly atmosphere, knowledgeable and helpful advice, use of new technology and methods, consistent and kind care. Dr. Thomas, Dr. Nguyen, and Dr. Jaswal have all demonstrated genuine care and interest in their patient’s lives, dental health and history, and other medical concerns. I admire their dedication to providing excellent solutions to dental problems, and patience with special issues. I would recommend this team to everyone!”

“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.”

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.”

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.”

Barb Patterson

Happy Client from Mercer Island Office

“I needed a dentist close to home and they are close enough for me to walk. I've been twice now and both times had a great experience. Dr. Jaswal has a wonderful chair-side manner and super sense of humor.”

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.
