AN NGUYEN/Shutterstock 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.
Ulyana Khorunzha/Shutterstock Caramels are another sticky offender because they stick to teeth—not to mention expensive dental appliances like orthodontics. Like other sweets, caramels are best enjoyed after a meal and brushing and flossing immediately after eating limits the amount of time the stickiness sticks around in your mouth. Instead of a sweet treat, try one of these DIY Halloween decorations instead.
