Dental sealants are very thin coatings used to fill in deep grooves and pits in teeth that can harbour bacteria.
Sealants are applied to healthy chewing surfaces of the teeth to prevent decay and cavities – especially among children. According to the Centers for Disease Control, tooth decay affects more than half of children ages 6 – 8, and even older children and teens.
By applying sealants, families can prevent decay and save on the costs associated with filling cavities. If you plan to get dental sealants in, the CDC recommends doing so shortly after the molars have erupted from the gums – usually beginning around age 6.
