I want to have my tongue pierced. Will it damage my teeth? There is a temptation to fiddle with a tongue piercing and this can damage the teeth - biting down on the metal could chip your teeth. There are other risks that go with having your tongue pierced. It could cause an infection, which might make your tongue swell. If this happens, you run the risk of blocking your airway. An infection could also cause blood poisoning, which could be life-threatening. I'd like a jewel fitted in my tooth. How can I do it? Having a diamond or other jewel fitted into the front of one of your teeth can be quite fashionable, but it should be done properly. Dentists are in the best position to do this as the procedure involves applying acid and a very strong glue to the tooth. Don't be temtped to ask an unqualified person to do it - if it's not applied properly, it may work loose and could be a choking hazard.
