Tongue piercings may be trendy, but biting down on the metal stud can crack a tooth. Lip piercings pose a similar risk. And when metal rubs against the gums, it can cause gum damage that may lead to tooth loss. The mouth is also a haven for bacteria, so piercings raise the risk of infections and sores. Bottom line, discuss the health risks with your dentist first.
The bacteria in plaque will also break down starchy foods into acid. This acid can attack the teeth for the next 20 minutes -- even longer if the food is stuck between the teeth or you snack often. You might want to floss after eating potato chips or other starchy foods that tend to get stuck in the teeth.
