Just thought I'd follow up to let you all know I did get the root canal and it was fine! I didn't feel a thing and it was over with quickly. However, I did have a super bad infection in there, so he put some antibiotic in the tooth and covered it with a temporary filling. I have to go back in a month to get the temporary filling removed, and if the infection has cleared up, I will get the permanent filling then, followed by a crown.
