A dental sealant is a thin, plastic coating placed on the chewing surfaces of the back teeth—specifically molars, premolars, and any deep grooves known as pits and fissures. These grooves are where more than 75% of tooth decay begins, as they are difficult to clean and highly prone to cavities. By applying a sealant, these areas are sealed off, creating a smooth surface that is much easier to keep clean and less likely to develop decay.
Sealants offer long-lasting protection against cavities, but it’s important to have them checked regularly during dental visits to ensure they haven’t worn or chipped.
Reasons for Sealants
- Children and Teenagers: Sealants are recommended as soon as the six-year molars (the first permanent back teeth) come in, or at any point during the cavity-prone years from ages 6 to 16.
- Adults: Sealants may also be beneficial for adults who have deep grooves or depressions in teeth that have not developed any decay.
- Baby Teeth: In some cases, sealants are applied to baby teeth with deep grooves or in children who are especially prone to cavities.
What to Expect When Getting Sealants
Applying sealants is a quick and straightforward process, usually taking just a few minutes per tooth. First, the teeth are thoroughly cleaned and surrounded with cotton to keep them dry. Then, a special solution is applied to the enamel to help the sealant stick. After rinsing and drying the teeth, the dentist or hygienist gently paints the sealant material onto the enamel, covering all deep grooves or depressions. The sealant will harden either on its own or with the help of a special curing light, depending on the material used.
To help your sealants last as long as possible, maintain good oral hygiene, eat a balanced diet, and visit our dentist regularly for checkups.
