The Impact of Halloween Candy on Your Teeth

With Halloween comes ghosts, goblins and goodies — and the sugar in those treats can play some unwanted tricks in your teeth if you’re not careful.

Here’s why: The bacteria in your mouth are probably more excited to eat Halloween candy than you are. When the bacteria eat the sugar and leftover food in your mouth, a weak acid is produced. That avid is what can contribute to cavities.

But don’t hang up your costume just yet. The holiday is about candy, dressing up and having fun. It’s OK to eat that candy on Halloween as a splurge as long as you’re brushing twice a day and flossing once a day all year long.

To help you sort through the trick-or-treat bag loot, we have a rundown of some common candies and their impact on your teeth.

Hard Candy

Hard candies are ones to watch out for on Halloween. They can actually break your teeth if you’re not careful. You tend to keep these kinds of candies in your mouth for longer periods of time so the sugar is getting in your saliva and washing over your teeth.

Gummy Candies

Be picky if it’s sticky! These are some of the worst candies for your teeth. This candy is harder to remove and may stick longer on your teeth, which gives that cavity-causing bacteria more time to work.


Chocolate is one of the most popular kinds of candy handed out on Halloween. Chocolate washes off your teeth easier than other types of candy. Dark chocolate also has less sugar than milk chocolate. Just be sure to brush your teeth after you enjoy.

Sour Candy

You might want to pass on candies that make you pucker – especially if they are sticky and coated in sugar. Sugar candy can be very acidic – and that acidity can weaken and damage the hard outer shell of your teeth, making your teeth more vulnerable to cavities.
