"Per tooth LOL one can spend $800 on a root canal alone .."
Had one...my first...last month. $1195.00 for the root canal, plus $925.00 for the crown, just finished this week. That's downtown Philadelphia prices. It sure does look nice and feels good though.
Of course, I never had any problems with my teeth when my employer was paying for it. I'm retired and on my own with dental now!
