I hope the tooth holds on for you!Sour, I've never had a root canal.
I'm appalled by the cost of dental care. I nearly opted for an extraction vs a crown due to the expense. I've got another cracked tooth around an old filling that the dentist wants to crown for another grand. Suffice it to say, I still have a cracked tooth in my mouth.
For what you are going through with the root canal tooth, I'd be more inclined to have it yanked out.
They can be very painful if the tooth becomes infected
