You can repierce it just about any time.
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.
No Having any form of lump or bump next to a closed piercing indicates there is some form of issue with the piercing. This also depends on how long the jewellery has been out of the piercing and how long you had the piercing before removing the jewellery. If you develop any pain or discomfort seek the assistance of your doctor.
If the piercing is over a year old you can remove the Monroe piercing for several hours without fear of the piercing healing closed. Prior to a year you are taking a gamble on how your body will respond to the jewellery being out of the piercing.
If you're repiercing it because it was placed wrong, wait until it's closed completely. You don't want the holes to meet and rip. If you're repiercing it because part of it closed up, you can redo it at anytime.
It may not need to be repierced but simply tapered to open it enough for the jewellery to be replaced. Oral piercings don't close they generally just shrink.
eh.. mine closed in likee half hour.
As long as it takes. Not every piercing will close within moments of taking the jewellery out, there are other aspects that come into play. Length of time you had the piercing, the size of the jewellery, healing issues all these affect how fast a piercing will close. So as long as the jewellery is out the body will deal with it as it sees fit.
It really depends on the type of piercing and long you've had the piercing.
Well chances are good that the piercing may not close, it depends on how long you had the piercing before the jewellery is removed. Most of my clients get the jewellery replaced with a PTFE barbell which is ultra flexible made of surgical Teflon they manage to keep the piercing right through to delivery with no problems. If you have had the piercing for over a year, chances are good the piercing wont closed but it will shrink without jewellery in the piercing. You can get the jewellery put back in by seeing your piercer and having them use an insertion taper to reinsert the jewellery.
It depends on how long you had the original piercing, how big or what gauge the piercing happens to be, and the state of your over all health. If you are in good shape and the piercing is fairly new then things should heal up in about 6 to eight weeks if the jewellery is removed soon enough. If you are doing this because the original piercings were "botched". The might I recommend you see a Professional Body Piercer instead of the individuals at the mall who generally don't know or care about what they are doing. Your will get better results without having to get them repierced over again a.k.a. Getting it done right the first time.
You'll need to give the piercing area time to heal properly before getting it re-pierced. How long that is depends on how quickly your body heals, and how irritated the area got when you pulled the ring out. Good luck!
