The skin will usually close over within hours of taking it out. Cartilage takes longer to heal, possibly up to a couple of years. You might feel a small divot there under the skin. Due to the placement of the daith though, it’s extremely unlikely anybody but yourself will notice it.
Secondly, how long does it take for a piercing to close up?
It’s hard to predict how quickly your body will attempt to close a piercing, but as a general rule, the newer it is, the more likely it will close up. For instance: If your piercing is less than a year old, it can close in a few days, and if your piercing is several years old, it can take several weeks.
