A root canal is a rather simple procedure, especially on
front teeth. They are much easier than people think (not the dreaded thing everyone claims them to be). The dentist should get you numb, and after that everything is painfree. After, you should feel no pain, and the only discomfort you might feel would be from the healing bone where the body is still fighting the infection outside the tooth.
If your tooth is mostly intact, there is no reason the dentist would need to remove it.
