I got lucky -- the dentist said that after having braces, there was enough room left over in my mouth for my wisdom teeth to stay. Knock on wood, they've given me no trouble so far.
Of course in order to get the braces, I had to have a large chunk of my gums removed that was sticking in between my two front teeth. They even took that bit of connective skin that keeps the upper lip connected to the gums. They drugged me up nice and good (I still remember floating along on a blood cell, watching the doctors above me), but the following week or so was nothing but pudding and Slim Fast shakes.
