Use of BPA in Dental Sealants

When it comes to giving safety to the child’s dental health, you may be thinking about getting his/her teeth sealed using a sealant. Dental sealants are known to provide great protection against several dental infections including tooth decay and cavities. However, the point of concern, when choosing the application of sealants, is that most of the sealant solutions contain BPA.

Dental sealant usually contains BPA, which is a manmade chemical, in very small amount. The main point of concern about this chemical is that it poses the safety risk. Nevertheless, dental sealants have been proven to provide great protection against tooth decay, and dentists are not sure how dangerous the amount of BPA present in the sealant usually is.

Bisphenol A (BPA)
BPA is the short term used instead of the name Bisphenol A. this chemical is usually included in the food can linings, polycarbonate food and drink containers, water bottles, and other products which we use every day. A tiny amount of this chemical is used in the dental sealants. Although this chemical is quickly broken down by the body, it possesses similar behavior that of estrogen which is believed to be linked with the increased risk of diseases.

Some studies suggest that BPA is linked with a number of health conditions which include heart diseases, obesity, diabetes, an increased risk of miscarriage, and alterations in liver enzymes.

BPA in dental sealants
The trace amount of BPA is left in the dental sealants during manufacturing process. This tiny amount of BPA is then released into the mouth after application of sealants. According to American Dental Association, BPA is used in the starting phase of sealant manufacturing. At the end of production, the amount of BPA is usually very tiny.

Since dental sealants are not made to last forever, the BPA present in the sealants is likely to be ingested.

Risk and benefits
It is unknown whether the amount of BPA present in the sealants is dangerous but the protection that sealants can provide against a number of dental health infections is known to everyone. Although many people are exposed to BPA on daily basis but the major reason for it is not the use of dental products. This BPA usually comes from processed foods and drinks which are packed in the cans and bottles. ADA also suggests that the amount of BPA present in the dental sealants has not been found much of a health risk.

Nevertheless, the safety of your children is surely going to be your utmost priority. Therefore, you can discuss it with your dentist whether or not the dental sealants are good for your children.
