Root canal or extraction?
I have had 2 root canals, one crowned, one filled. Not cheap. Both had to be pulled within 3 yrs because they split to the root, or got infectrd and required new bone material in the jaw.
After all the pain, grief and expense, the faulty teeth had to be pulled and replaced with implants. Also, not cheap.
Knowing then what I know now, I would have had the bad teeth pulled and gone the implant route from the start. Would have saved pain, time and lots of money.
