A sealant is a thin, protective plastic coating applied to the chewing surfaces of molars, premolars, and any deep grooves (called pits and fissures) in the teeth. Over 75% of dental decay begins in these grooves, which are difficult to clean and more likely to develop cavities. Applying a sealant helps protect these areas by sealing the grooves, creating a smoother surface that’s easier to keep clean.
Sealants can safeguard your teeth from decay for many years, but they should be checked for signs of wear or chipping during regular dental visits.
Reasons for Sealants
- Children and Teenagers: As soon as the six-year molars (the first permanent back teeth) come in, or anytime during the cavity-prone years between ages 6-16.
- Adults: For tooth surfaces that have deep grooves or depressions but no existing decay.
- Baby Teeth: Sometimes recommended if the child has deep grooves and is at high risk for cavities.
What to Expect During Sealant Application
Applying sealants is a quick and simple process that your dentist or dental hygienist can do in just a few minutes per tooth.
First, the teeth to be sealed are thoroughly cleaned and kept dry with cotton. A special solution is placed on the enamel to help the sealant adhere. The teeth are then rinsed and dried again, and the sealant material is carefully brushed onto the surface, covering the grooves or depressions. Depending on the type of sealant, it will harden either on its own or with the help of a special curing light.
To keep your sealants in great shape, practice good oral hygiene, eat a balanced diet, and visit your dentist regularly.
