Dental Sealants
Dental sealants are thin, protective coatings applied to the chewing surfaces of the back teeth (molars and premolars) to prevent tooth decay. They act as a barrier, protecting the enamel from plaque and acids that contribute to dental decay.
Benefits
Highly effective in preventing cavities on treated surfaces
Quick, painless application process
Long-lasting protection for several years
Save money by preventing the need for fillings and other treatments
Particularly beneficial for children and teenagers
Can be applied to adults at risk for decay
Procedure Details
How Sealants Work
The chewing surfaces of molars and premolars have natural grooves and depressions where food particles and bacteria can collect. These areas are difficult to clean thoroughly with brushing alone. Sealants provide a smooth protective layer that covers these vulnerable areas, preventing food and bacteria from getting trapped and causing decay.
Application Process
Applying sealants is a simple, painless process that takes just a few minutes per tooth. First, the teeth are thoroughly cleaned and dried. An acidic gel is briefly applied to roughen the tooth surface for better adhesion. After rinsing and drying again, the sealant is painted onto the tooth enamel, where it bonds directly to the tooth and hardens. Sometimes, a special curing light is used to help the sealant harden more quickly.
Longevity and Maintenance
Sealants can protect teeth from decay for up to 10 years, but they need to be checked for chipping or wearing during regular dental check-ups. If necessary, they can be replaced. Sealants are most commonly placed on permanent molars as soon as they come in, typically between the ages of 6 and 14, but they can be beneficial for adults without decay or fillings in their molars as well.
Frequently Asked Questions
Are dental sealants safe?
Yes, dental sealants are safe for both children and adults. They've been used for decades with no adverse effects. Some sealants contain very small amounts of BPA, but not enough to cause any harm according to the American Dental Association.
Does getting dental sealants hurt?
No, the application of dental sealants is completely painless. There's no drilling or anesthesia required. The process is quick and comfortable, making it ideal even for young children.
Do dental sealants replace the need for brushing and flossing?
No, dental sealants only protect the chewing surfaces of the back teeth. You still need to brush twice a day, floss daily, and maintain regular dental check-ups to protect all surfaces of your teeth from decay and to maintain good oral health.
