It turns out that tongue piercings can be bad for one's teeth. While this is hardly a surprise to any dentist, it's been confirmed by a recent study from New York's University of Buffalo.

Researchers had previously found that teens with pierced tongues tend to "play" with the barbell-shaped piercing, often pushing the end of the stud against their front teeth — a habit that might leave them needing braces to fix the damage.

In this particular case study, a young woman who had had her tongue pieced for seven years developed a gap between her front teeth from pushing the barbell into the space between the teeth.

It's already known that a tongue piercing can increase the risks of chipping or cracking teeth, wearing down tooth enamel, receding gums, and more — now it's time to add orthodontic damage to the list.
