i'm going to the dentist tommorow

[Paper Boy]

i broke part of my tooth off early last year and the pain has really been getting to me the last 6 months. i almost passed out from the pain sunday night so i decided to go to the dentist on monday. he said i have a horrible infection in my tooth and he will need to extract it and perform a root canal. he will then stick a post where my horribly infected tooth was and at a later date he will put a fake tooth in it's place.

my question for you's is, has anyone ever had these procedures done? and will it hurt?
