Red Wine and Cranberries are Good for Teeth

Compounds found in red wine and cranberries can prevent cavities and plaque build-up.  The wine compounds, which are called polyphenols, do this by blocking a molecule made by the bacteria streptococcus mutans.

These molecules break down sugar to make sticky molecules called glucans, which let bacteria cling to your teeth and damage their surfaces.

Live Science reports:
“But the fermented grape stems, seeds, and skins left over from wine production contain high amounts of polyphenols. The polyphenols can block the ability of S. mutans to make glucans .  Compounds in cranberries work similarly — they block the molecules that enable the sticky surface to form on our teeth.”
