Dental sealants are thin, plastic coatings that are applied to the surface of the tooth to protect the grooves of the teeth from decay. Decay often begins in these grooves because they are hard to clean and susceptible to a buildup of plaque.
Sealants create a smooth surface that fills deep grooves and makes the tooth easier to clean and therefore minimizes the risk of having a decay.
Sealants are applied by cleaning the selected tooth and then painting the sealant onto the tooth enamel, where it will harden and bond to the tooth and protect it from decay. This procedure takes just a few minutes and is painless. Baby teeth can be sealed as well for children, which are proven to prevent decay.
