Sometimes brushing is not enough, especially when it comes to those hard-to-reach spots in your child's mouth. It is difficult for a toothbrush to reach between the small cracks and grooves on teeth. If left alone, those tiny areas can develop tooth decay. Sealants give your child's teeth extra protection against decay and help prevent cavities.
Dental sealants are a plastic resin that bonds and hardens in the deep grooves on the tooth's surface. When a tooth is sealed, the tiny grooves become smooth, and are less likely to harbor plaque. With sealants, brushing becomes easier and more effective against tooth decay.
Sealants are typically applied to children's teeth as a preventive measure after the permanent teeth have erupted. It is more common to seal "permanent" teeth rather than "baby" teeth, but every patient has unique needs, and the dentist will recommend sealants on a case-by-case basis.
Sealants last from three to five years, although it is fairly common to see adults with sealants still intact from childhood. A dental sealant only provides protection when it is fully intact so if your child's sealants come off, let the dentist know, and schedule an appointment for your child's teeth to be re-sealed.
