What if you could simply brush your teeth and say, "Look, Ma, no more tooth decay!"

According to Popular Science, that just may be the case if a newly-patented product proves it can do what its creator says it can.
Jeffrey Hillman, a dental researcher at the University of Florida and owner of the company, Oragenics, has created a simple swab of bacteria he says will give your set of choppers a lifetime of protection.
Here's the idea: Normally a bacteria called Streptococcus mutans grows on human teeth and converts sugar into lactic acid which rots the enamel. Hillman has engineered a strain of this bacteria that doesn't produce the lactic acid. Instead it carries an antibiotic, which throws the bacteria off-track. This fall the new bacteria strain will be tested on volunteers. Hillman will swab the bacteria on their teeth and then, you're not going to believe this, tell them to go home and eat sugar! That's right. They can load up on all the Tootsie Rolls, caramels, and sweet sodas they want.
The idea is to colonize the new bacteria strain, and instead of creating a cavity, which is what sugar normally would do to bare enamel, the sugar helps form a tooth security guard.
It's very much like a vaccination, introducing a little bit of the disease so the body will create antibodies to fight the real thing.
There is one slight hitch at the moment. Hillman isn't sure if the new bacteria strain will be transferable to others through kissing. He's pretty sure it isn't, but just in case, the spouses of the first batch of testers will be monitored too.
If everything goes according to plan, the new swab could go commercial within five or six years. In the meantime, put down that Tootsie Pop!
