Depends on how your body heals, what size the piercing is, and how old it is. Its really difficult to give you a definitive answer, sorry.
It can take up to 12 weeks for an Industrial piercing to close up. Possibly even longer, as long as you clean the area with salen solution it will heal up just fine, DO NOT turn, the piercing it will do that by daily wear. And DO NOT take the piercing out, the skin will grow back together very quickly and cause the punctures to close, meaning you just paid for a piercing, that is no good anymore.
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.
Most piercings that are fresh will close up within a matter of an hour to a few hours of the jewelry being out, and even a well healed piercing will close up after a few days of no jewelry being worn...unless the piercing is stretched, but even then, you have at most two to three days of wearing nothing before it begins to shrink.
Nope. It will only close up if you have an infection
It really depends on the type of piercing and long you've had the piercing.
if its a fresh piercing the hole will close up pretty quickly, if you've had it for a while the hole will probably take a while to close up
Like any hole in the body that wasn't there by design the piercing will close if jewellery is not kept in the piercing. The speed at which the piercing closes will be dictated by the period of time the jewellery has been kept in the piercing, the longer jewellery is worn the longer it will take for the piercing to close up.
after a couple of monthes but i think you still have a small scar afterward
It depends on how fast your body heals, and how long you have had the piercing. The longer you have had the piercing, the longer it will take to close. This is true for all piercings.
It depends on where it is pierced. The lobes can take about 3 months to completely close up, where your cartilage can take 6 months to even a year to completely close up. It also depends on how long you have had the piercing. A piercing that you've had for years can take years to close (in my personal experience).
a septum piercing never closes completly, sorry
Yes. After a couple hours.
