it depends on how recently you had the piercing done. so if it's within the first week or so chances are the skin might grow back together although you will still have a scar at the site. if it's longer than that chances are you will always have at least a potential space there. however if there is an infection it does need to be evaluated by a doctor and treated and the piercing may need to be removed until the infection has cleared at least.
i got my bellybutton pierced but i think it’s infected. if i take the piercing out will the skin grow back together?
