Why tooth decay could be caused by your genes

DO YOU have a mouth full of fillings? You might have the cavity gene.

There is increasing evidence some people are more prone to cavities thanks to genetics.

In fact, according to Mary L. Marazita, director of the Center for Craniofacial and Dental Genetics at the University of Pitts- burgh, around 60 per cent of the risk for tooth decay is due to genetic factors, as genes influence things such as the strength of your enamel. They also influence how well you can taste, says research in the Journal Oxford Academic. And the greater your ability to taste, the less likely your teeth are to decay.
