If I were you KitKat, I would put your stage 1 off until you get your tooth sorted. You want to be on tip top condition and even if the pain is bearable, you don't need anything to give you grief.
Just my 2 cents and don't worry about the clothes, some guys were there on my stage 1 in jeans and t shirt AND I seen them at my stage 2!
Best of luck anyway!
