Question: I had a root canal earlier this week and now I need a cap/crown to cover the old, dead tooth. The endodontist took care of the root canal then filled it. The tooth, though a little sore but getting better, seems to work just fine like it always has -- just that it's dead. Questions is, how long can I go with the tooth as is until I absolutely need to get the crown put on by my regular dentist? The endodontist said I should take care of it sometime within the next month. I'm a little cash-strapped and would like to stretch it out a little longer. The root canal cost me $200 with dental insurance and I know crowns can get expensive as well. Anyone know? Thanks.
