Plasma Jet: The Ultimate in Painless Dentistry

A new device called a "plasma jet" could soon be used to treat dental cavities without the need for a dentist's drill and fillings. The space-age plasma gun shoots a low-temperature beam of electrically-charged oxygen atoms into small cavities in your teeth, killing the bacteria that cause them and allowing the tooth to heal naturally. Unlike a drill, the plasma jet is non-invasive and pain-free... great news for the millions of people around the world who fear the dentist's chair!

Special note: Using toothpastes and chewing gum flavored with xylitol has been shown to be a natural way to prevent tooth decay and possibly even allow your teeth to "fix" cavities on their own (aka enamel "remineralization"). Now that's what we call totally painless dentistry!
