Some scientific studies have suggested that BPA, like soy and phthalates, may affect reproduction and development in animals by mimicking the effects of the female hormone estrogen, thereby raising concerns about its safety. To date, these effects have not been observed in humans and are questionable at the exposure levels resulting from consumer and dental products.
The ADA believes any concern about potential BPA exposure from dental sealants or composites is unwarranted at this time. When compared with other sources of BPA, these dental materials pose significantly lower exposure concerns.
