The Nutrition Connection

Eating sugar, as you probably already know, is a major cause of tooth decay. But it's not just how much sugar you eat — when and how you eat it can be just as important to keeping teeth healthy.
When you eat sugary foods or drink sodas frequently throughout the day, the enamel that protects your teeth is constantly exposed to acids. Hard candies, cough drops, and breath mints that contain sugar are especially harmful because they dissolve slowly in your mouth. Many experts suggest that you take a 3-hour break between eating foods containing sugar.
Sugary or starchy foods eaten with a meal are less harmful to your teeth than when they're eaten alone, possibly because the production of saliva, which washes away the sugar and bacteria, is increased. Eating sugary foods before you go to bed can be the most damaging (especially if you don't brush your teeth afterward) because you don't produce as much saliva when you sleep.
For most people, it's hard to cut out sweets completely, so try to follow these more realistic guidelines:

• Eat carbohydrates (sugars and starches) with a meal.
• If you can't brush your teeth after eating, rinse your mouth with water or mouthwash, or chew sugarless gum.
• Don't eat sugary foods between meals.
• If you snack, eat nonsugary foods, such as cheese, popcorn, raw veggies, or yogurt.
