Ever heard of the ill effects the chemical bisphenol-a have on children? The substance has been subject to much debate being part of polycarbonate plastics or the clear plastic bottles that are used for sippy cups, baby bottles and other food containers. It has the nasty ability to leach out of the product that contains it should it be exposed to high temperatures that led to it’s banning for use in baby products first in Canada then the rest of the developed world. As it turns out, some of the composite plastics used for teeth fillings contains the same chemical that makes it durable so safety issues are being raised about the safety of such plastic fillings. Scientists have been trying to develop the ideal filling material for use in the dental industry that has labeled silver fillings unsafe due to concerns with mercury poisoning. Chinese and Canadian scientists have been able to develop a composite using bile acids from which the tooth filling material is synthesized from an enzyme produced naturally in the human body and stored as part of bile or the green stuff stored in the gallbladder resulting in a tough plastic that has proven to be better than the first two teeth filling materials of choice.
