Dental Sealants
Protect your teeth from decay with our top-notch Dental Sealants service. A quick and painless procedure that offers long-lasting benefits for your oral health.

What Are Dental Sealants?
Dental sealants serve as a protective shield for your teeth, particularly the molars and premolars. These sealants are a thin, plastic coating applied to the chewing surfaces of your teeth to prevent cavities and tooth decay. At Thomas Dentistry, we offer this quick and effective treatment to help you maintain a healthy smile for years to come.
The procedure is simple, painless, and can be completed in just one visit. Dental sealants are especially beneficial for children who are more prone to cavities, but adults can also take advantage of this preventive measure. It’s an investment in your oral health that can save you time and money in the long run.
Sealants are a proven method for reducing the risk of cavities. They act as a barrier, sealing off deep grooves that are hard to clean and are prone to develop plaque. With dental sealants, you can eat and drink with confidence, knowing that you’ve taken an extra step to protect your teeth.
How Do Dental Sealants Work?
Dental sealants work by forming a smooth surface over the natural grooves and pits in your teeth. This makes it difficult for food particles and bacteria to hide, reducing the risk of cavities. At Thomas Dentistry, the process is straightforward and can be broken down into a few simple steps.
The application of dental sealants is a quick and painless procedure. First, the tooth is cleaned and dried. Then, an acidic gel is applied to the tooth’s surface to roughen it up, helping the sealant bond better. Finally, the sealant is painted onto the tooth and hardened with a special light. The result is a durable barrier against decay.
Process of Applying Dental Sealants:
- Cleaning: The tooth is thoroughly cleaned to remove any plaque or food particles.
- Preparation: An acidic gel is applied to create a better bonding surface.
- Application: The sealant is painted onto the tooth’s surface.
- Curing: A special light is used to harden the sealant, securing it in place.
With dental sealants, you’re taking a proactive step in your oral health. They offer an additional layer of protection that complements regular brushing and flossing.

Understanding the cost of dental sealants is crucial for making an informed decision. At Thomas Dentistry, we strive to offer competitive pricing without compromising on quality. While the cost can vary depending on various factors such as the number of teeth needing sealants, we offer multiple payment options to make the process more affordable for you.
We believe that preventive care like dental sealants should be accessible to everyone. That’s why we accept a range of insurance plans and also offer financing options. Our team is more than happy to discuss costs and payment plans with you, ensuring you get the best care without any financial stress.

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.”

Peter Christian
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.”
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!”
