Dental work without drills? We're there

Machine uses ozone to zap cavities

This isn't exactly at gadget you'd want to purchase for your home (we hope), but trust us--you'll want to know when it's available. The University of Buffalo is leading research into dental work that can be done without drilling or anesthesia, based on a device that uses ozone to repair cavities.

The bacteria-killing ozone machine, which is being used in Europe, "fits over a tooth and forms an airtight seal in arresting tooth decay," according to Medgadget. Researchers say the technology is being tested now in the United States and, if approved, could be available to U.S. dentists in two years. We could say that we're aching to try it, but that would be wrong.
