Dental sealants reduce the risk of decay by nearly 80% in molars.

The first step in the dental sealant process involves thoroughly cleaning the teeth that will be sealed. This is done to ensure that no plaque or food particles are trapped underneath the sealant. Your dentist in Fremont will use a rotating brush and a gritty toothpaste to clean each tooth. After cleaning, each tooth is dried and an absorbent material is placed around it to keep it dry.
Once the teeth are cleaned and dried, an acidic gel is applied. This gel roughens the tooth surface so the sealant can strongly bond with the tooth. After a few seconds, the dentist will rinse off the gel and dry the tooth again. Then, the dentist will apply the sealant onto the grooves of your tooth. The sealant is a liquid at this stage.
After the sealant has been applied, it needs to be hardened, or cured. To do this, your dentist will shine a blue light on the sealant. This light helps the sealant harden and bond to the tooth surface, effectively sealing off the grooves of the tooth from plaque and acid. Once this is done, you have a newly sealed tooth that is better protected against decay.
Sealants have been shown to remain effective for five years or more even with normal chewing.
