I had a molar root canal treatment done on the NHS, She told me at the time that the roots were complex and she wasn’t guaranteeing success. She offered me a referral to a endodontist but said she was prepared to take it on. What should have been 3 visits turned into 5 visits but she thought she’d done it. It never quite ‘settled down’ and she told me that, after 6 months it was unlikely to ‘go right all by itself’ – sooner or later it would be either extraction or re-treatment by endodontist. So off to the endodontist it was and he seems to have fixed it. One thing he did say though was that “root canal treatment is an exercise in delaying extraction“. It may outlive me. I may get 10 years out of it – in which case I’ll be glad I had it done. If it needs pulling in 5 years of less, I’ll wish I’d had it pulled at the very beginning.
only problem I have is occasionally getting a peanut caught in the gap.
^ my main reason for not wanting an extraction – I have a bag of salted nuts pretty much every time I go to the pub.
