Cavities often begin in the deep grooves of a child’s back teeth, where toothbrush bristles cannot reach. Dental sealants create a smooth, protective barrier over the tooth surface and significantly reduce the risk of tooth decay. Parents naturally want to understand how this treatment works and whether it is safe for children. Sealants have been used for decades and remain a trusted part of preventive pediatric dentistry.

Why Dentists Trust Dental Sealants
Sealants add an extra level of protection during the years when molars are most prone to cavities, typically between ages 6 and 12. The material bonds to the chewing surface and creates a durable coating that helps keep bacteria away from vulnerable enamel. Once placed, sealants offer reliable, long-term support for both baby molars and permanent molars.
Benefits include:
- Lower cavity risk by as much as 80 percent during the first two years
- Protection for both baby molars and permanent molars
- A smoother chewing surface, which helps kids clean their teeth more effectively
- Several years of durability before repair or reapplication is needed
Are Dental Sealants Safe?
Sealants have a long track record of safety, supported by research and major health organizations. They are made from dental materials designed to stay stable in the mouth. These materials do not release harmful levels of chemicals and are considered safe for children of all ages.
| Did you know? Sealants are BPA (bisphenol A) free. A tiny, temporary trace can appear during curing, but exposure is far below everyday environmental levels. |
How Sealants Are Applied
Sealant application takes a few minutes per tooth and is completed by a pediatric dentist or dental hygienist during routine dental visits.
- Molars are cleaned and dried
- A mild etching gel prepares the enamel
- The sealant is painted into the grooves
- A curing light hardens the coating
Kids can eat normally as soon as the appointment ends.
Sealants and Daily Oral Hygiene
Sealants significantly lower the risk of cavities, but they work best alongside consistent oral hygiene. Children still need to brush twice a day with fluoride toothpaste, floss once daily, and maintain regular dental checkups.
These habits keep the enamel strong and prevent plaque from building up around the sealed areas. Sealants protect the deep grooves of molars, while daily brushing and flossing protect the rest of the tooth surface and gums.

FAQs
Does dental insurance cover sealants for kids?
Many dental insurance plans cover sealants for children because they are considered a preventive service. Coverage can vary by plan and age, so it is helpful to check your specific benefits before scheduling.
How long do dental sealants last?
Sealants can last several years with normal chewing and regular brushing habits. During routine checkups, the dentist will check each sealant and recommend repair or reapplication if any wear or chips appear.
What are dental sealants made of?
Most pediatric dental sealants are made from resin-based materials or glass ionomers designed to bond securely to enamel. These materials are stable, safe for children, and formulated to protect the chewing surfaces of molars.
