Crocodelight

Ever wonder why those huge crocs and alligators lie in the sun, mouth agape? Well those ancient reptilians knew something we did not: light cures plaque. That's right. Soon we will get toothbrushes with a light at the tip. As if it is not enough that we already get ones that, using a simple AAA cell, vibrate, massage, give us a haircut, become a light saber (optional) etc. I am not pulling your leg. An excerpt:

Scientists have developed a mouthwash that allows plaque-causing bacteria to be destroyed using nothing more than a bright light.

Leeds Dental Institute say it may be available inside three years for home use - perhaps with the light attached to the head of a toothbrush.
