Bacteria Fights Bacteria to Prevent Cavities

NEW YORK - It is a case of the good, the bad and the ugly-- or more specifically -- good bateria fighting bad bacteria to prevent cavities.

In new research from the Karolinska Institute in Huddigne Sweden, scientists gave laboratory rats doses of "good" bacteria lactobacillus to determine if levels of cavity causing "bad" Streptococcus mutans bacteria would be influenced. It worked. Their research showed rats that received the good bacteria developed far fewer cavities, leading researchers to believe probiotics may one day be suited to prevent tooth decay.
