Protect Teeth with Dental Sealants
Sealants help protect teeth from decay by covering the surface, particularly the back teeth where brushing can be more challenging for children. Made from a clear liquid resin, sealants harden when exposed to a special light, forming a smooth, hard surface that prevents food from getting trapped in the grooves of the back teeth.
Studies show that sealants can reduce the risk of decay in treated teeth by up to 80%. The CDC also notes that children without dental sealants are up to three times more likely to develop decay in those same teeth compared to children with sealants.
How Are Sealants Placed?
First, the tooth or teeth are cleaned, dried, and isolated using either cotton rolls or a rubber dam. A special gel is then applied to etch the teeth, roughening the surface to help the sealant material bond better. After rinsing off the gel, the sealant is applied to the grooves of the teeth and hardened with a light. Once all the teeth are treated, the dentist checks for any rough edges and ensures floss can pass between them.
In general, dental sealants have no side effects unless your child is allergic to one of the resin ingredients, which is very rare.
Caring For Your Child’s Sealants
Sealants are durable and can last up to 10 years, although they may need to be replaced sooner depending on your child’s habits. Avoiding chewing on ice and hard candy can help extend their lifespan and prevent chipping, which could allow decay to start inside the tooth. The dentist will check the sealants during each visit to ensure they remain intact.
While sealants don't replace the need for regular brushing and flossing, they provide added protection and can even help stop minor decay from worsening.
