What Are Dental Sealants?

Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth (molars and premolars). They create a barrier that blocks out food and bacteria, reducing the risk of cavities in hard-to-reach grooves.
Sealants are especially effective for children and teens, but adults without decay or fillings in these teeth can also benefit.

Tip: Dental sealants work best when paired with regular dental cleanings, which remove plaque and keep teeth healthy between visits.

Why Dental Sealants Matter

Even with daily brushing and flossing, some areas of the mouth are tough to clean. Sealants help by:


1. Reducing the risk of cavities in molars and premolars
2. Protecting teeth during cavity-prone years (ages 6–14)
3. Supporting long-term oral health for children, teens, and adults
4. Saving money by preventing the need for future fillings and restorations.

Like night guards, sealants are a preventive solution that protects teeth from damage before it starts.

The Sealant Process: Quick and Comfortable

At our O’Fallon office, applying sealants is a simple and painless procedure:
1. Teeth are cleaned and dried.
2. A special solution prepares the tooth surface.
3. Sealant material is applied to the grooves of the tooth.
4. A curing light hardens the sealant in seconds.


The process usually takes just a few minutes per tooth and can provide years of protection.
