A cool new addition to dentistry is something that's been around for over 100 years. That's the addition of ozone to the mix. It sterilizes without using chemicals and is friendly to our bodies aerobic composition. Here's a video where a dentist explains how critical this is to his own practice. It actually frightens him now to go a day without it's use with his patients.

Ozone is simply an oxygen molecule on steroids (O3).... very caustic to anaerobic unfriendly bacteria, (which don't posses the enzymes to protect themselves from oxidation)... while our own body cells and friendly aerobic bacteria are complimentary with this exposure....
Ozone therapy, in general, is proving to be an amazing application for so much of what ails us! It's being widely used in Europe and is only just now gaining some traction in the US. It was just recently assigned it's own insurance code and is gaining legal ground in some states:

In the USA, recently passed Alternative Therapy Legislation has made ozone therapy an option for patients in some states. In Alaska, Arizona, Colorado, Georgia, Minnesota, New York, New Jersey, North Carolina, Ohio, Oklahoma, Oregon, South Carolina, and Washington, physicians can legally use ozone treatments in their practice without fear of prosecution.
