Dental Sealants are meant to protect the back teeth from food residue and germs, hence preventing tooth decay. Sealants are thin plastic coatings put on the chewing surface of the morals (back teeth). Adding this coating, fills in any grooves and pits in the tooth, which prevents food and germs from getting trapped in places, which your tooth brush can’t reach. When done in early age, your child’s molars can benefit from this preventive measure.
