If the hole is not infected and it has only been a short period of time (a few days) then it is fine if you get a needle, just make sure it's clean and your hands are too, and some ice cubes if you want, and just push it on through.
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.
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.
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
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.
The length of time you have the piercing for will be three times that period for the piercing marks to close up and disappear.
No. Go talk to your doctor if you want the piercing to close up that badly. Over time the piercing will shrink and will become unnoticeable
Honestly, I have had my labret piercing for about 7 months now and I took it out for about 4 hours for a class. At the end when I tried to put the piercing back in it hurt. The hole were the piercing was seemed to have tightened up. It took a few hours for my piercing to feel like it usually does. So I would guess that a labret piercing would close up kinda fast
Your question isn't very clear, but I will give it a shot. The time it takes for a navel piercing to close or "heal up" depends on how long you have had the piercing. The longer the piercing has been in place with jewellery, the longer it will take for the piercing to close with the jewellery removed. Generally if you have had the piercing with jewellery over a year the piercing can take several months to shrink down to the point where you can't put jewellery into the piercing any longer. If you have only had the piercing for a few months then it can take a few weeks for the piercing to close.
