a septum piercing never closes completly, sorry
A new tongue piercing can start to close within hours to days if jewelry is removed, as the tongue is a fast-healing area due to its rich blood supply. However, it can take several weeks to fully close up depending on individual healing characteristics and how long the piercing has been in place.
It depends on how old the piercing is. If it's over a year old, then you can go a couple of days. If it's under a year old, then a couple of hours. The newer the piercing is, the less time you have with it removed before it starts becoming difficult to put it back in. If it closes, then go in to see your local professional body piercer for some help.
You can get it done again once you're sure the piercing is healed inside as well as out.
A pierced belly closes quickly if you have not worn a ring consistently for about a year. If the hole closes, it may just be partially closed and it can be "punched" out again easily.
Oral to dermal piercings will close from the inside to the outside. If the piercing is over a year old then you may get a day to 48 hours out of it before it tries to close up. Under a year you may be lucky to get a few hours.
Ahhh the piercing closes and you need to get it repierced..

2-3 months before the piercing can be submerged. You can go swimming now as long as the piercing doesnt get wet.
It depends on how long it's been in the tongue but also is different from person to person how fast it closes, but I Recomend You Buy A Retainer For Your Piercing Seeing As They Are See Through.
whenever you would like, as long as it isn't infected. removing the jewelry in any infectd piercing can cause an abscess (when the entry and exit closes off first, the infection will be trapped.
