That was a joke. I actually went to the Walmart nurse practitioner the first time...they don't prescribe pain medicine there. Half the damn doctors in my town won't prescribe pain medicine (due to too many addicts? I dunno). I don't buy pain pills on the street. My ENT specialist hooked me up. Still healing. Not sure of the progress, but if I'm not better in two weeks, I have to have surgery.
For me, my orthodontist wouldn't put my braces on until all mine were removed. When they break the skin, they can cramp your mouth more. I had braces for 5 years and had to have 4 more teeth after that pulled. I was a snaggletooth lol.
The main reason they usually remove wisdom teeth though, is because they are hard to reach and decay faster as a result from lack of brushing. That's what I'm told, at least.
