Halloween Candy and Your Kids' Teeth: A Parent's Game Plan

Halloween is one of the best nights of the year for kids, and one of the busiest for cavity-causing bacteria. The good news: you don't have to be the parent who confiscates the candy. What matters most for teeth isn't just how much sugar kids eat, but which treats they choose, when they eat them and how long the sugar stays on their teeth.

How sugar causes cavities

Bacteria in the mouth feed on sugar and produce acid. That acid softens tooth enamel for roughly 20 to 30 minutes after each snack. Saliva gradually neutralizes the acid and helps enamel recover. Trouble starts when kids snack again and again, so their teeth never get a break from the acid. That's why frequency matters as much as quantity.

Not all candy is equal

Some treats are much harder on teeth than others.

Tougher on teeth:

• Sticky and chewy candy, such as caramels, taffy, gummies and fruit snacks, which cling to the grooves of the back teeth
• Hard candy and lollipops, which bathe teeth in sugar for a long time and can crack teeth if bitten
• Sour candy, which adds acid on top of the sugar
• Sugary drinks, which coat every tooth surface

Easier on teeth:

• Plain chocolate, which melts and rinses away quickly
• Chocolate with nuts, if there are no allergies
• Sugar-free gum, which actually boosts saliva and helps protect teeth

A game plan that works

• Eat treats with meals. Saliva production is higher at mealtime, which helps wash away sugar and neutralize acid. Candy as dessert is better than candy as an all-afternoon snack.
• Pick a treat time. Rather than letting kids graze from the bag all day, choose a set time for a few pieces.
• Drink water afterward. A glass of water rinses sugar off the teeth. Fluoridated tap water is even better.
• Wait to brush. Brushing right after acidic or sour candy can scrub softened enamel. Wait about 30 minutes, or rinse with water first.
• Brush and floss before bed, every night. This is the most important habit. Sugar left on teeth overnight does the most damage because saliva flow drops during sleep.
• Sort the stash. Let kids keep their favorites and trade or donate the rest. Some families do a "switch witch" swap, trading candy for a small toy or an outing.

Extra care for kids with braces

Braces and candy are a tricky combination. Hard, sticky and chewy candy can bend wires and pop off brackets, and sugar easily gets trapped around the hardware. Stick to soft chocolate, brush carefully after treats and avoid caramel, taffy, hard candy and popcorn. Clear aligner wearers should remove aligners to eat and brush before putting them back in.

Don't forget the adults

Office candy bowls and leftover trick-or-treat candy are tempting for grown-ups too. The same rules apply: treats with meals, water afterward and a solid bedtime routine.

Year-round protection

Halloween is a good reminder that prevention works. Regular checkups, fluoride and dental sealants on the back teeth make a big difference in how well kids' teeth handle the occasional sweet. Read more in our post on sealants and fluoride for kids, or visit our pediatric dentistry page.

Schedule a fall checkup

If your child hasn't had a checkup in the last six months, the end of October is a great time to come in. Request an appointment online or call Zen Family Dental at (703) 385-2772. Happy Halloween from all of us!
