80% of tooth decay in children occurs due to debris trapped in vulnerable areas (pits, fissures, and grooves), which are hard to clean with a toothbrush or dental floss. Dental sealants fill these vulnerable areas to prevent the debris from getting trapped and accumulated.
A dental sealant is a thin film of clear plastic, which is used to coat pits, fissures, and grooves present on the chewing surface of back teeth or molars. It creates a smoother and regular tooth surface, which is easier to clean and also more resistant to debris accumulation. Mostly, children get their teeth sealed but people of all age can take advantage of dental sealants to protect their teeth against caries and cavities.
