Dental Sealants

Teeth brushing and flossing are the best ways to help prevent cavities, but it’s not always easy to brush and floss clean every nook and cranny of the teeth, especially those back teeth you use to chew (molars). Molars are rough, unseen and a favorite place for leftover food and cavity-causing bacteria to hide. But then, there is another safety net to help keep the teeth clean, called dental sealants.

Dental sealants or fissure sealants is a thin, plastic coating, painted on the chewing surfaces of teeth, usually the back teeth (premolars and molars) to prevent tooth decay. Dental sealants quickly bond into depressions and grooves the teeth, forming a protective shield over the enamel of each tooth.

A dental sealant is a preservative treatment of that is part of the minimal interventions of dentistry approach to dental and oral care. It facilitates the prevention and quick intervention, in order to prevent or stop the tooth decay process before it reaches the end stage of disease, which is known as the cavitation of a tooth. As soon as the tooth is cavitated, it requires dental restoration in order to repair the damage, this emphasizes the importance of prevention in preserving our teeth for a lifetime of chewing.


Dental sealants can be thought of as a raincoat of the teeth. When the cavity-causing bacteria that live in the mouth meet leftover food particles, they produce acids that can create holes in the teeth. The application of sealants keeps this bit of food out and stops bacteria acid from settling on the teeth, just as the raincoat keeps the rain from beating you.


Dental sealants can be applied as soon as child’s permanent back teeth, the molars have fully grown. This is done so that the deep grooves and pits that are seen on the chewing surface of the teeth are filled in before cavities sets in. Protecting the molars and premolars from the very start greatly reduce the chances of getting cavities or worse dental issues later in life.

Most times sealants are applied during childhood, some adults may need to have them applied later in life if they never had the procedure done earlier or if there is the development of pit in teeth where there was none previously.


As soon as a dental sealant is applied, and set on a tooth, it requires no special treatment. The patient only needs to continue brushing twice daily and flossing regularly. Additionally, protection and an extra brilliant smile can be gotten through the use of a fluoridated, non-alcoholic mouthwash after brushing the teeth.
