Before you start munching on a snack, ask yourself what's in the food you've chosen. Is it loaded with sugar? If it is, think again. Another choice would be better for your teeth. And keep in mind that certain kinds of sweets can do more damage than others. Gooey or chewy sweets spend more time sticking to the surface of your teeth. Because sticky snacks stay in your mouth longer than foods that you quickly chew and swallow, they give your teeth a longer sugar bath.
Also think about when and how often you eat snacks. Do you nibble on sugary snacks many times throughout the day, or do you usually just have dessert after dinner? Damaging acids form in your mouth every time you eat a sugary snack. The acids continue to affect your teeth for at least 20 minutes before they are neutralized and can't do any more harm. So, the more times you eat sugary snacks during the day, the more often you feed bacteria the fuel they need to cause tooth decay.
If you eat sweets, it's best to eat them as dessert after a main meal instead of several times a day between meals. Whenever you eat sweets - in any meal or snack - brush your teeth well with a fluoride toothpaste afterward.
If you snack after school, before bedtime or other times during the day, choose something without a lot of sugar or fat. There are lots of tasty, filling snacks that are less harmful to your teeth - and the rest of your body - than foods loaded with sugars and low in nutritional value. Low-fat choices like raw vegetables, fresh fruits or whole-grain crackers or bread are smart choices.
Eating the right foods can help protect you from tooth decay and other diseases.
