How long will it take for a hole in the ear cartilage made about a year ago to close after taking out the earring?

Eveyone is different, so healing times may vary. but generally after the ear ring has been removed from the cartilage, usually anywhere from 2 to 6 months. As I said, everyone is different, so your healing time can vary. You may notice a tiny dot from the scar tissue building up as it does heal, which is normal.
