What Happens If Dental Sealants Are Applied Over a Cavity?

Dental sealants are popular for their use as a preventive measure to protect teeth from decay, especially in the molars where grooves and pits can trap food and bacteria. 

Potential Complications

However, applying dental sealants over a cavity can lead to complications if the cavity is not properly addressed beforehand.

Bacteria and Food Particles

Sealants are designed to block out bacteria and food particles, but if they are applied over an existing cavity, they may seal in the decay. This can result in the cavity continuing to grow underneath the sealant, potentially leading to more severe tooth decay or even infection. While sealants are incredibly effective at preventing cavities, they should not be used as a treatment for existing decay.

Before applying sealants, your Panorama City dentist will thoroughly examine your teeth to ensure there are no cavities. If decay is found, it must be treated first through fillings or other appropriate dental procedures. This ensures that your teeth remain healthy and the sealants can do their job in protecting against future decay.
