Root canals with crowns are expensive, even with insurance.

Try to find an endodontist that has financing available and that may take your insurance, if your insurance will cover any of it (I can't remember, but I think I was out about $1200 bucks for the root canal and crown).

I had my root canal done with these folks: https://www.marylandendodontics.com/ My tooth was fractured. Got the root canal done that same day with a temporary crown.
