My second premolar (if am not wrong) is decayed and broken to half its size. My dentist suggested root canal on it. I also have braces so he also told me that the crown will be placed when the braces are removed. But looking at the cost and the amount of care to be taken, I am holding back. I would prefer extraction because anyway it isnt helping me in chewing and two of my teeth need filling so i would first spend money on saving them. What should i do?
