As popular as tongue and mouth piercing is with young people these days, they may not realize that the piercing procedure itself can lead to severe bleeding and infections, and in some cases, the tongue can become infected and swell so much that it may cut off breathing. In addition, tongue jewelry gets in the way of talking and eating, and commonly causes chipped or cracked teeth. Make sure that anyone in your household considers the consequences of oral piercing carefully before making any impulsive decisions.
