More than 90 percent of children go trick or treating and return home with bags full of sugary candy that can turn anyone's mouth into a nightmare. By taking a few preventive steps, however, children can enjoy Halloween without harming their teeth.

Since sugar-free gum is one treat that actually helps prevent cavities, it is a smart choice to drop in Halloween bags. Parents can also give it to their children to help neutralize the effects of sugary snacks after eating. Chewing sugar-free gum containing the artificial sweeteners sorbitol and xylitol reduces cavities. The chewing motion stimulates the flow of saliva, which helps cleanse the teeth.

Sweets are especially harmful, since damaging acids form in the mouth every time you eat a sugary snack and continue to affect the teeth for at least 20 minutes before they are neutralized. The sweetening agents in sugarless gum are effective in combating the bacteria in plaque and fighting the acid that eats away at enamel.

Certain foods such as sweets and soda are easily linked to tooth decay, however all foods can promote tooth decay if eaten in excess. The key is to teach kids to eat in moderation and make sure that they take proper care of their teeth.

"While healthy alternatives to candy, such as fruit and nuts, are great, these foods are sticky and can get caught in the pits and grooves of teeth, causing decay," says Academy of General Dentistry spokesperson Julie Barna, DMD, MAGD. "Reading nutrition labels and being sensible about the foods you and your children eat on a daily basis helps promote good oral and overall health."

Children should also brush three times a day for two minutes and rinse with a fluoridated mouthrinse.
