The reason candy, in general, is harmful to teeth is that bacteria in the mouth burn the sugar, creating acid as a byproduct, explains Matthew Messina, DDS, spokesperson for the American Dental Association (ADA).
The acid then dissolves tooth enamel, which is what causes cavities. Chewy candies, including gummy candies and taffy, are among the worst offenders because they linger and stick around in your mouth, giving them additional time to cause tooth decay. Not to mention some are sticky and strong enough to pull out a filling, bridge, or braces. Opt for one of these healthy Halloween candies instead.
Sure, Halloween treats are loaded with sugar, but so are these surprising foods.
