My dentist mentioned i "possibly" need a root canal. He said that i have a lot of tooth decay. I am concerned that if the decay is considerable i might need a bridge. The thing is i dont feel much pain on this tooth so i dont know whether i should feel a lot pain or if he is just trying to take my money. So my questions boils down to the following: if there is considerable tooth decay do i need an extraction and then a bridge? Should i feel pain if i have tooth decay?
