University of Florida health researchers have identified a new strain of good bacteria in the mouth that may keep bad bacteria from causing cavities. Have you ever noticed that some people, no matter how hard they try to take care of their teeth at home, consistently get cavities? Though caries risk has a lot to do with diet and hygiene and access to fluoride, an equally important component is your mouth chemistry, involving genetics and the way your body effectively neutralizes acid.
Researches identified that patients with fewer cavities have more of a certain bacteria called A12 that helps neutralize acid in the mouth and battle the cavity-causing bacteria S. mutans. Eventually, they may be able to use these findings to create an effective probiotic from the beneficial bacteria, to reduce cavities and plaque in high-risk patients.
