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.

“Very incompetent doctor dr. Thomas is after money. Don't believe anything he is saying. Other doctors are all recent college graduates with no experience. Don't trust them. Get a second opinion or just go some place else get your teeth done.”

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.”

“Very very exceptional service, from making the appointment all the way to check out.”
Madeleine Dow
Happy Client from Mercer Island Office
“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.”

“Cathy did an amazing job cleaning my teeth! She was informative on what is going on in my mouth! Looking forward to my next cleaning!”
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.”
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.”
Lukas Rogers
Happy Client from Kirkland Office
“Dr. Thomas and his team have managed my dental care for over a decade and I couldn't be happier with how I've been treated. Highly recommend coming in to see him for anyone in need of dental care.”

“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!”
