Removing a monroe can be a little tricky, I’ve had some funny experiences trying to remove mine at times! I usually place my thumb and index finger on the ball and then slip my other thumb and index finger inside my mouth and place them on the back of the disc. I then turn each side in opposite directions and can usually undo it. However, if it has been done up too tightly you may need to seek assistance. In this case, I recommend going to a piercing parlour and ask for help there. They will usually do it without any charge!
if you are referring to the piercing Monroe it is an upper lip piercing
monroe or dahlia. monroe piercing is usually around the area similar to Marilyn Monroe's beauty mark. a dahlia piercing is right at the corner where the two lips meet.
it hurts less than a cartilage piercing but more than a monroe.
A Monroe is the upper left lip and a Madonna is the upper right lip
an upper lip
Any body piercing studio will carry spacers.
Call a piercing studio and ask.
It's up to you, but the Monroe to actually be a Monroe would be done on your left cheek.
