My Wisdom teeth came in by the time I was 20 without me even knowing they did. The dentist said I didn't have room for them (which made no sense to me because they were already in!) and they needed to come out. He also stated they could come out in office visits one by one. OK lets do it then. The top two came out real easy (probably why he did them first!) The bottom left one, was another story! Jesus, he yanked on that damn thing for 5 minuets, at some point I stopped him and said "I'm really glad I can't feel what your doing, cause it sound like it hurt's like HELL!" He finally got it out and pointed out that it had three roots instead of the more common two, and I left. OMG! when the Novocaine wore off I thought I was going to freaking DIE! And it hurt for two freaking months! Needless to say, he didn't get to pull the last one.
