This is what my Friend did to me, when I was 14. I will post a picture of him when I have one.
Were still friends, good friends but I needed to show every one what happens when your blind folded and near him. He hits you in the face and bam, You almost loose 2 of you teeth.
I have since had 2 root canals as 2 abscissas had formed in the roots of my teeth. I had the root canal with out any anaesthetic, becausethe nerves and blood vessels were dead.

Thanks to flickr.com I was able to post these photos.
