Dental sealants are primarily made of a composite liquid resin that is then cured by light or chemical exposure to adhere to the tooth. Most sealants contain a small, trace amount of BPA, but not nearly enough to cause any harm. In fact, you get more exposure to BPA by touching a receipt or handling makeup powder than dental sealants.
With proper oral care, dental sealants can effectively last for up to 10 years. If it is not in working condition, the dentist will replace the dental sealant as needed. Applying sealants is a quick and painless process. There is no drilling or scraping involved. Typically, a dentist will clean the tooth first then apply a gel-bonding agent to it. Then, the dentist will apply the sealant and cure it with a special blue light, or chemical rinse. After the bonding is dry, the dentist will then clean any residue left on the tooth, and the procedure is done!

A dental sealant is a thin plastic film painted on the chewing surfaces of teeth to prevent cavities. Studies have proven that properly applied sealants are percent effective in protecting the tooth surfaces from cavities.
As long as the sealant remains intact, small food particles and bacteria that cause cavities cannot penetrate through or around a sealant. Sealant protection is reduced or lost when part or all of the bond between the tooth and sealant is broken. However, clinical studies have shown that teeth that have lost sealants are no more susceptible to tooth decay than teeth that were never sealed.
Sealants protect those areas and prevent food and bacteria from getting in. Your dentist can apply sealants easily, and it takes only a few minutes to seal each tooth. The dentist first cleans the teeth that will be sealed, which may require the use of a dental drill to open the grooves of the teeth and determine if decay is present.
Then he or she will roughen the chewing surfaces with an acid solution, which will help the sealant stick to the teeth. It bonds directly to the tooth and hardens.
Sometimes your dentist will use a special curing light to help the sealant harden. Sealant treatment is painless and takes anywhere from five to 45 minutes to apply, depending on how many teeth need to be sealed. Sealants must be applied properly for good retention. As long as the sealant remains intact, the tooth surface will be protected from decay.
Sealants hold up well under the force of normal chewing and usually last several years before a reapplication is needed.
