Cavity-fighting candy?

In the Dec 27 edition of the week, an article talks about microbiologists in Berlin who are working on probiotic-laced mints that fight tooth decay. Apparently the probiotics used for the candy, like those normally found in yogurt, can "attach itself to and neutralize" the bacteria that turns sugars into teeth-damaging acids. So one day, your candy might actually fight cavities instead of causing them!
