Sealants are a protective dental treatment commonly used to prevent cavities, especially in children and teenagers. They consist of a thin, plastic coating applied to the chewing surfaces of the back teeth (molars and premolars), where cavities often develop due to their uneven surfaces and difficulty in cleaning. The sealant material bonds to the pits and grooves of the teeth, creating a smooth surface that helps block out food particles and bacteria, reducing the risk of decay.

The application of sealants is a straightforward and painless procedure typically performed during a routine dental visit. After cleaning and drying the teeth, the dentist or dental hygienist applies the sealant material onto the chewing surfaces of the teeth and then uses a special light to harden and bond the sealant to the tooth enamel. Sealants are highly effective in preventing cavities and can last for several years with proper oral hygiene and regular dental check-ups. By providing an additional barrier against decay, sealants help maintain the health of the teeth and promote long-term oral health.
