When we were kids most of us loved chocolate. However, many times when we would ask for our favorite treat we had our request denied. Our parents would say things like "It will rot your teeth!". In recent years researchers have made some discoveries that kids across America will want to know. It's now being said that it's not the sugar content in food that causes tooth decay, but how long it stays in your mouth. So, a piece of chocolate won't cause too much harm; it's food like cookies that tend to stick to your teeth that will cause decay.
