The American Dental Association recognizes that piercing is a widely accepted form of self-expression, and that includes piercings in the mouth. However, the potential problems from piercings are numerous. Some symptoms after a piercing include pain, swelling, infection, drooling, taste loss, scarring, chipped teeth, tooth loss, and an increased flow of saliva, none of which are particularly pleasant. Tongue piercing can also cause excessive bleeding. If you’re thinking of placing a piercing in or around your mouth, talk to your dentist first. If you already have piercings and are having problems, see your dentist right away.
