A body piercing is just what it sounds like a piercing or puncture made in the body by a needle. After, a piece of jewelry is inserted in the hole. Commonly pierced body parts are the ears, nose, and the belly button. Oral piercings include the lip, cheek, and tongue. When a piercing is healed, some people will choose to expand the size of the hole to wear certain types of jewelry, including plugs and tunnels. Stretching should be done in small increments to decrease the chance of damage to the piercing and scarring.
