Why you should consider sealants

　　Brushing and flossing are the best ways to prevent cavities.Molars,our back teeth,are often difficult to reach and clean.Anatomically,molars have deep grooves and rough surfaces.This creates a place for leftover food to stick and bacteria to grow.When these bacteria and food particles meet,they produce acids that damage tooth enamel and cause tooth decay(cavities).

　　Sealants are another way to help protect the chewing surfaces of your molars from decay.A sealant is a thin,clear or white protective coating made of dental material that is bonded to the chewing surface of the tooth.Sealants can help prevent cavities from forming and inhibit the progression of early decay.The thin coating acts as a protective barrier,covering the anatomy of the occlusal surface.Studies show that sealants can reduce the risk of molar cavities by 80 percent.However,sealants are not a replacement for brushing and flossing.

　　Applying a sealant is much less invasive than filling.This is a simple and painless process.Sealants usually last several years before needing to be reapplied.The condition of the sealant will be checked regularly during regular dental visits and can be reapplied as needed.

　　Children can also benefit from sealants.First molars erupt around age 6,and second molars around age 12.Sealing these teeth early can help prevent tooth decay.At the dentist's discretion,sealants may be used on early-stage decay to prevent further damage.
