Do you buy those probiotic yogurts that are supposed to help your digestion? Can't say I do, but lots of people swear by them. Now it looks like 'friendly bacteria' could help our teeth too.

A bacterium called Streptococcus mutans lives in our mouths and causes tooth decay. Researchers have now shown that another bacterium called Lactobacillus paracasei, which is found in fermented milk, can grab hold of S. mutans and prevent it from causing mischief.

In Croatia you can already buy probiotic toothpaste containing L. paracasei. Would you use it?
