Sealants are a applied to teeth to help prevent future decay. They are most effective when applied within the first two years after a permanent tooth's eruption.
How it's done
After the tooth is cleaned and polished, the chewing surface of the tooth is treated with a conditioner to help the sealant adhere to the tooth. Once the tooth is conditioned, it is thoroughly dried and the sealant material is applied. The sealant is then hardened with an intense blue light. The whole procedure takes about 3 minutes and can be performed by the dental hygienist.
