What Is the Life Span of Dental Sealants?

For extra cavity-fighting protection, a thin, protective coating called a “sealant” can be applied to the molars. This treatment has proven to reduce the risk of decay by about 80 percent. It’s especially effective with children, according to the Centers for Disease Control and Prevention, which notes that “school-age children without sealants have almost three times more cavities than children with sealants.” Patients often ask how long sealants last. In this article, we will address that question, along with other pertinent facts about sealants.

How Do Sealants Work?

Cavities are caused by acid released by mouth bacteria. The acid destroys tooth enamel, which creates decay. Using a helpful analogy, the American Dental Association explains: “After sealant has been applied it keeps those bits of food out and stops bacteria and acid from settling on your teeth—just like a raincoat keeps you clean and dry during a storm.” two young girls holding their mouths laughing

Who Can Get Sealants?

Anyone can get sealants, but they’re primarily recommended for those who are especially prone to cavities, such as teens and young kids. The earlier teeth are sealed, the more effective it will be. The first set of molars erupt around age 6, with the second set appearing around age 12. Sealing these teeth as soon as they appear will help protect them from ever getting cavities.

How Are Sealants Applied?

Getting sealants is a quick and easy process. The tooth is cleaned and dried, then an acidic gel is placed on the teeth for a few seconds. The gel roughs up the tooth surface, enabling the sealant and tooth to form a strong bond. After rinsing off the gel, the tooth is dried, and the sealant applied onto the grooves of the tooth. The sealant is then hardened with a special blue light.

How Long Do Sealants Last?

Once sealants have been applied, the National Institute of Dental and Craniofacial Research estimates they can last up to 10 years with proper care. And there’s no need to have them removed, because they gradually wear away. If you or your child have sealants, they can be checked for wear at every regularly-scheduled tooth cleaning.
