A dental sealant is a thin coat of plastic sometimes used on your teeth to protect it tooth decay. This is most often done on your back teeth like the molars, but can also be done on other teeth. The sealant will bond to your tooth like a coat of armor to act as a protection for your enamel and tooth. Sometimes brushing and flossing is just not enough to keep the food and tartar from sticking to certain teeth and the sealant can help with these areas.
The dentist can apply the sealant easily by painting it directly onto your teeth after a thorough cleaning. This protection can last for up to 10 years as long as you visit your dentist regularly to have it checked for chips or cracks.
