Sealants

You are most likely to develop cavities anywhere on your teeth that doesn’t have a smooth surface. Even if you brush your teeth regularly, sometimes it is impossible to get debris and bacteria out of the pits and crevices on your molars and premolars, which is where your food gets chewed after you bite it. That’s why dentists came up with the idea of a sealant. Sealants are applied on top of molars and premolars in order to prevent cavities.

Sealants actually were developed during the 1960s, but weren’t commonly used until after FDA approval in the early 1970s. Sealants are popular because they are effective. Dentists often use them on young children to prevent cavities because, in many cases, they don’t have tooth decay yet. Sealants fight additional damage even when decay is already present.

The first step in applying a sealant is to clean the surface of the tooth. Next, the dentist etches the tooth with something that allows the sealant to stick better. Finally, the dentist promotes faster drying by using a light. Sealants usually have to be applied again every five to 10 years.
