Know the risks before you have your body pierced:
Bacterial infection (where you had the piercing)
Excessive (a lot of) bleeding
Allergic reactions (to certain kinds of jewelry)
Damage to nerves (for example, you may lose feeling at the area that gets pierced)
Keloids (thick scarring at the piercing site)
Dental damage (swelling and infection of the tongue, chipped/broken teeth, gum trauma, choking on loose jewelry)
Some people who have not looked at the pros and cons about getting a piercing may regret their decision. You should never feel pressured into getting a piercing.
