GOOD TO KNOW: Eat these foods to keep your teeth healthy

Everyone knows that sugar contributes to cavities because it feeds harmful bacteria in the mouth. But recent research suggests that avoiding sugar alone does not ensure good oral health.

Other foods also play a surprisingly important role in the health of teeth and gums. Scientists are still working to understand the importance of the oral microbiome, the microscopic community living in the mouth.

It contains about 700 species of bacteria, along with viruses and fungi. Despite its considerable effect on overall health, the oral microbiome is often overlooked.
