I would suggest you locate a reputable biologic dentist who performs cavitation surgeries and find out. Many dentists do not want to know about this kind of thing, so you'll need to find one that works in this area.

Here is one link where you might be able to find a dentist or ask the dentist on there if he can help you find a good one or check out the dentists directory and find one in your area or near enough to. Here is the link - http://www.holisticdentalnetwork.com/biocompatible.php
