Nothing, you are just going to have to let it shrink on it's own. Also keep makeup out of the hole or you will have more issues down the road.
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
A small hole will be visible. The longer you have had the piercing, the longer it will take to close. If you want the hole to close, do NOT try putting anything through it to see if it is shrinking. This will only prolong the closing process.
Depends on the age of the piercing, the gauge, and just how your body heals. Most do close but they leave scars.
No, it can close up if you don't keep something in it.
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.
It most likely will close to a normal hole, but if the piercing was stretched to quickly it may not 100% (due to the fiberous nature of scar tissue)
As long as the body takes to minimize the piercing and close it, there is no magic solution that will make it close faster. It's just a matter of time.
It varies, if you have had the piercing for a long time the hole might never close. It does vary, i got my ears pierced over 3 years ago and still close overnight.
Putting a hole in the forging after it is made. Can be done hot or cold. Usually done on a press with a punch.
the hole will close over or it could get infected
you don't need to. you just take the piercing out and it closes. it might take awhile but eventually the hole will close
Why would you need to repierce it if it hasn't closed? If it's too shallow or crooked, yes, close it up. You don't want the new piercing hole and the old one to meet and tear to form a single hole.
