A person can change a navel ring once the puncture wound has healed, which takes approximately nine months to one year, according to the Center for Young Women's Health. Healing time varies, based on the care the navel ring receives.
To allow a navel ring to heal properly so that it can be changed, the navel must receive air to help the healing process. It is best to avoid wearing tight clothing and belts that can irritate the piercing and increase the risk of infection, according to the Center for Young Women's Health. Clean clothing made of soft fabrics is ideal.
