root canal?

[RandomName]

A friend of mine has had a dentist say she likely needs a root canal. She dug all through PubMed, but can't find much research on the topic. Anyone know of some good data on pros/cons?

No. I used to have some, but my dentist took off with it, and then lost it. i've not replaced it since I never intend to have one.
