Can tongue piercings give you cancer?

I don't know that: It can cause cancer, but it certainly can cause dental problems. Professionally, y would not recommend getting one. Hope this helps.

Have seen no studies: to suggest that. But they can cause other problems. According to the British Dental Association the potential for infection is higher for the tongue than any other location on the body. Swelling of the tongue can compromise the airway. Ludwig's Syndrome (Ludwig's Angina) can cause swelling & sepsis both of which can lead to death. Staphylococcus aureus / Streptococcus pyogenes can enter tissues
