Root canals are a bitch

So I have three deep cavities in my mouth. One on the left and two on the right. Last year in May I went to the dentist and he told me I need to have root canals done on each of them. I said "ok." This man had the nerve to say "Ok so it's $250 each one not including the caps because your insurance only covers half." I just left because I'm a poor, sometimes employed college student. I can't afford to pay for them and for the past year it's been ok. I just avoid eating sweets and chewing on my hind teeth. The past week the nerves in my teeth must be exposed because I can't anything for shit. Not even an hour ago I got some relish stuck in the crevice in my tooth and it hurt like a bitch. LIKE A BITCH.
