I got two wisdom teeth pulled in my teens. Not much of a problem. But, in my mid 20s, the other two were a nightmare. They were huge each with six roots. They had to chissel them apart and pulled out in pieces. However, the surgeon didn't remove all the pieces and both sides got infected. Then he had to go back in, dig everything out including the infection, and stitch it all back up. Very painful. He said the holes would fill it eventually. But, then never did. So, now food gets trapped in there every time I eat. I have to run my finger back there to push the food out. Blaaaaaaa.
