Dental sealants are a thin, plastic coating painted on the chewing surfaces of teeth to prevent tooth decay. They usually are placed on the back teeth. The sealant quickly bonds into the depressions and grooves of the teeth, forming a protective shield over the enamel of each tooth.
Although brushing and flossing can remove food particles and plaque from smooth surfaces of teeth, they cannot always get into all the nooks and crannies of the back teeth to remove the food and plaque. Sealants protect these vulnerable areas from tooth decay by "sealing out" plaque and food.
Because of the likelihood of developing decay in the depressions and grooves of the premolars and molars, children and teenagers are candidates for sealants. However, adults without decay or fillings in their molars can also benefit from sealants.
Typically, children should get sealants on their permanent molars and premolars as soon as these teeth come in. In this way, the sealants can protect the teeth through the cavity-prone years of ages 6 to 14.
In some cases, dental sealants may also be appropriate for baby teeth, such as when a child's baby teeth have deep depressions and grooves. Because baby teeth play such an important role in holding the correct spacing for permanent teeth, it's important to keep these teeth healthy so they are not lost too early.
