What should be done if air bubbles are noted in a sealant?

When air bubbles are identified within a dental sealant, the appropriate course of action is to apply additional sealant after rinsing and drying the affected area. Air bubbles can compromise the effectiveness of the sealant, potentially leading to areas of demineralization or dental caries beneath the sealant where bacteria might thrive. By addressing the bubbles through this method, you ensure that the sealant adheres properly to the tooth surface and provides the necessary protection against decay.

Rinsing and drying the area first allows you to clean the surface and ensure a proper bond for the new application. This method ultimately enhances the longevity and efficacy of the sealant, aligning with best practices in dental procedures.
