What Causes Tooth Decay
To understand why some snacks are better than others, it helps to remember what causes tooth decay in the first place. Our mouths are populated by millions of bacteria that feed on the food left behind when we eat, and those bacteria leave acids behind as a byproduct of digestion. The more sugar and starch in those foods, the more acid — and the higher the incidence of tooth decay.Foods to Avoid
If we’re trying to avoid tooth decay — whether for ourselves or our kids — we can start by not laying out a banquet for bacteria. Starchy and sugary foods like candy, soda, fruit juice, and certain fruits should be avoided or eaten in moderation. Some foods, like gummy bears, Starburst, and even raisins, have a tendency to stick to teeth and hold the acid in place; avoid those, too. And don’t think that savory foods are always the answer, since starches like potatoes and corn break down in the mouth in much the same way sugars would (in addition to the added sugars contained even in savory snacks).Foods to Pack
There are a number of foods that can keep kids satisfied between meals without raising the risk of cavities.- Yogurt. Dairy is nutritious and helps build strong teeth and bones, but check sugar content.
- Cheese is filling and has proteins and calcium for strong teeth. String cheese can be fun to eat, and some cheeses also taste great with other foods on this list.
- Apples and celery, since the fiber keeps bellies full and also helps clean teeth.
- Hummus with pita chips, veggies, or pretzels can be a healthier alternative to junk food.
- Nuts are tasty and also have lean protein, without the starch and additives found in chips.
