Good news for Merlot and Cabernet Sauvignon fans – red wine could be good for your teeth and help ward off tooth decay, according to new research. Italian scientists found it contains chemicals that stop harmful bacteria from sticking to teeth and suggest a daily glass of red could help to keep teeth healthy and reduce the need for fillings.

Unfortunately, if you prefer white wine it’s not such good news. A recent study showed white wine could damage dental health because its high acid content erodes the enamel that coats the surface of a tooth.

Red wine, when drunk in moderation, is already thought to have a protective effect against heart disease and some forms of cancer.
