Happy Client from Mercer Island Office
“This is the best dentistry in the PNW! Molly at the front desk is so kind and always makes me feel like one of their VIP clients. The dental hygienists are all kind and Doctor Thomas is a straight shooter. Both myself and my Mom visit this office and couldn’t recommend it more!”

“Dr. Nguyen and the dental hygienists are super nice! I felt comfortable and safe—even the time I started crying when I had a panic attack before getting some cavities filled. (Sorry about that lol.) Anyways, Dr. Nguyen was very kind, gave me space to chill out, and didn’t make me feel embarrassed, even though I wouldn’t have blamed him if he did.”

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.”

“I truly love my dentist and the wonderful staff. I’ve been a patient for almost six years and my visits have all been a good experience. I feel confident and well cared for. Everyone is friendly and very professional. 100% Thank you all!”

Happy Client from Mercer Island Office
“I did not have a dentist in the Seattle area and choose Thomas Dentistry because they were close and nearby. Boy, did I strike gold! I hadn't been to the dentist in a while and I needed some work done to get clearance for a other medical procedure. They were so great in getting me set up and expediting my treatments. Everyone was very professional and friendly. I can highly recommend them for your dental work.”

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.”

“Everyone is very kind from the start. I have high anxiety dealing with my teeth and dentists; and everyone was incredibly helpful and informative! I'm really happy I found this place for my smile needs!”
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.”
