Tooth decay is caused by bacteria found in the mouth and the presence of sugars.
These acidic byproducts immediately start to demineralize the enamel of the teeth. However, if the bacteria and acidic materials are removed quickly, the tooth is sometimes able to remineralize itself. The bacteria and acid can be removed by brushing and flossing after every meal. Over time, demineralization can cause a hole, or cavity in the teeth. That is why it is very important to brush your teeth at least once every 24 hours, however, twice or more is suggested.
