When You Should Wait on Sealant
Before your dentist or dental hygienist can move forward with sealants for you or your kids, you'll want to make sure no significant problems exist.
You should also know that sealants do contain a small amount of bisphenol A (BPA), a chemical that's present in plastics. Many parents avoid products with BPA because it has been linked to health problems in children and infants, says the Mayo Clinic. However, the Food and Drug Administration and the American Dental Association (ADA) report that the amount of BPA in a dental sealant is so low - that it is not harmful. Though a small amount of exposure occurs for a few hours after placement, current evidence shows there are no dental sealant dangers from this low-level exposure, says the ADA.
The only downside to using sealant is whether you might have an allergy to it. The good news is reactions related to dental sealants are extremely rare. The Journal of Clinical & Diagnostic Research reports only one case where asthma and hives occurred after a sealant was placed, but subsided after it was removed. As always, it's best to talk to your dentist about any allergies and follow the recommendations of your dentist before moving forward with the treatment.
Finally, a dental sealant can last a long time, up to 10 years, and the procedure is, many times, covered under dental insurance. After the initial treatment, your dentist will check for chips or cracking during regular checkups and the sealant material can be cleaned off of the tooth surface and be re-applied.
