Dental sealants

Dental sealants are a thin, plastic coating painted on the chewing surfaces of teeth — typically the back teeth (molars and premolars) — to prevent tooth decay.

Overview

Dental sealants form a protective shield over the enamel of each tooth. They act as a barrier against the bacteria that cause cavities, especially in the areas of teeth that are hard to clean with regular brushing.

Application Process

1. Cleaning: The tooth is thoroughly cleaned.
2. Conditioning: After cleaning, the tooth is conditioned to help the sealant adhere properly.
3. Applying Sealant: The sealant is painted onto the tooth enamel, where it bonds directly to the tooth and hardens.
4. Setting the Sealant: A special light may be used to help the sealant harden after application.

The process is quick, painless, and can be easily completed during a regular dental visit.

Benefits

• Protection Against Decay: Sealants can protect teeth from decay for up to 10 years, but they need to be checked for chipping or wear during regular dental check-ups.
• Cost-effective: Prevention of cavities reduces the need for fillings and other more costly dental procedures.

Considerations

• While sealants are beneficial, they do not replace the need for good oral hygiene. Regular brushing, flossing, and dental check-ups are essential.
• Sealants are more commonly applied to children’s teeth, but adults can benefit from them too.
