Dental sealants are usually applied to the chewing surfaces of the back teeth where decay most often occurs. They are primarily used in children between the age of 6 and the onset of puberty, as this is the time when most cavities are likely to form. The sealant is applied to cover the uneven surfaces of the teeth where bacteria develop and multiply. Sealants are painted onto the teeth and then set with a special light. According to the American Dental Association (ADA), about 20% of American children have sealants in their mouths.

Concerns have surfaced regarding the use of sealants. Studies conducted in Spain found that sealants released a chemical known as BPA into the saliva. BPA is classified as an endocrine disruptor, a chemical that interferes with the body's production and utilization of certain hormones. These disruptors are associated with an increased risk of testicular and prostate cancer in men, and breast cancer and endometriosis in women. Endocrine disruptors may also suppress the immune system.

The ADA maintains that sealants are safe and effective.

See a doctor if you or your child have experienced serious health problems after receiving dental sealants. In addition, it may be important to contact an attorney who can help you protect your legal rights. Please keep in mind that there may be time limits within which you must commence suit.
