A study confirmed that bisphenol A (BPA) forms after a dental procedure using dental sealants and tooth fillings.

BPA is an organic compound used by manufacturers in producing plastic bottles, food containers and epoxy resins with other products. There are studies suggesting the negative effects of the compound in the body. Other researchers claim that BPA can cause elevated levels of hormones such as estrogen and testosterone. Furthermore, exposure to the compounds can cause problems with growing babies and children.

Manufacturers of dental sealants and fillings do not include the compound BPA in their products. However, upon the application of the sealants in the mouth, a chemical reaction begins between the sealant and the saliva. The reaction produces BPA levels in the oral cavity. This raised concerns to parents of children having the dental procedure.

Abby F. Fleisch, MD, a pediatric endocrinologist, and a group of experts investigated the issue. They examine evidences pertaining to the claim. Results show that there is an elevated level of BPA in the mouth after the dental application of the fillings and sealants.  The researchers noted the high levels of BPA three hours after the procedure. However, the team was not able to propose evidence concerning the potential threat of the increased amount of BPA in the oral cavity.

Furthermore, the experts noted that wiping and rinsing the area, which has the sealant, could dramatically reduce the generation of BPA afterwards. They found that there was about 85% to 95% decrease in the formation of BPA after scrubbing and rinsing the dental work.

Weighing between the health benefits acquired after the procedure and the risk with the usage of the products, experts agreed to recommend the continue usage of the dental sealants. However, they advice practitioners to observe precautionary measures when doing the dental works.
