Mine grew in around 18-20 I got braces right before I turned 20 and we knew they would come out before the braces came off.
Never caused pain until one day last oct my cheek was swollen, that one had to come out that week, had the others pulled the week before xmas
no pain, screamed once heard a crack and I was out cold from the little blue pill.
Drooled, bled a bit, threw away one sweater, slept with a towel over pillow, gauze for a day, no soda or carbon drinks for a week, never took a pain pill just one for nausea :-)
it hurt most to get a bad silver filling out this month and a temp crown but was having other fillings done and they gave me like 10 needles (that hurt the most haha)
