A new study finds dental sealants commonly used to prevent cavities may expose children to BPA, a controversial chemical thought to be linked with health problems.
Researchers found that materials used in sealants can break down into BPA when they come in contact with saliva.
BPA levels can spike to 88-times higher than normal right after a dental sealing, but then quickly drop off.
Doctors aren't sure how much of the chemicals are absorbed into the body.
They say the benefits of dental sealants outweigh the possible risks from BPA exposure.
