KTH Flashback: BPA in Dentistry: Safety & Risks
Posted on Wednesday, October 14th, 2015
Anymore, the terms “BPA” and “avoid” go hand in hand. Unfortunately, BPA and related compounds turn up in a lot of dental composite – the type of material used to make tooth-colored fillings and a major alternative to mercury amalgam. (Porcelain and other ceramics are other options.) A conscientious biological dentist will make every effort to avoid such materials. Compatibility testing can rule them out.
But what if you already have composites? Should you be worried about possible exposure? Should you get those fillings removed?
Biological dentist Dr. Bill Glaros’ answer to such questions is good and concise:
First, know that when BPA is present in a composite resin, the amount released is very small – though like so many environmental toxins, it is bioaccumulative and may add to your total body burden. Still, if the dental work involved isn’t causing any immediate health problems that either you experience or are detected through EAV or other testing techniques, removing the composite is apt to do more harm than good. The trauma each tooth would undergo through the removal process would do more harm than any benefit of lower BPA exposure would give.
Eventually, they will need to be replaced due to age and wear (which can be as long as 10 or even 20 years for some materials). That’s when to make sure they’re replaced with a BPA-free, biocompatible material.
Recently, we came across this presentation by dental materials expert Jess Clifford – an excellent and accessible talk on the safety profile of BPA in dental materials. For an accurate look at what BPA is, its role in dentistry and its potential impact on health, we think it’s a clip well worth your time:
