Should my dentist have known I'd a fourth root?!

Should my dentist have known I'd a fourth root?

A couple of weeks ago I asked if I needed to return to my dentist after an extraction. I had some really good replies. I rang my dentist up and he told me that because the part of the root he had left in was so far up, it was virtually impossible for it to be the part of the root he'd left in and was more likely to be bone. He told me that it should come out within a few days. It didn't and was painful, so today I went back. I had got some bone protruding (as I knew) which he removed without me feeling it, however when he said there was a larger piece and was having difficulty removing that (as if I wasn't aware by how painful it was and how long it was taking him) surprise, surprise he told me I'd a fourth root which he removed.
Shouldn't he have known this from either the Xrays or when he was extracting the tooth a fortnight ago?
I go as a private patient and I really have no faith in him anymore. Can I ring Denplan up and just change dentists?

Heather. Thank you for your help. I realise I seem totally paranoid about my mouth and the experience. I was hoping someone could say it was perhaps a common mistake and he wouldn't have known I had a fourth root. I guess I really wanted to think I was being overly sensitive and paranoid rather than not trust my dentist. I am going to change.. thanks

As I stated the last time you ask a question about this tooth and dentist; you need to find a new dentist. The fourth root isn't always visible on an x ray "but" should have been realized upon examination of the extracted tooth and "should have been" removed at that time, not later. If an x ray had been taken post op, it would have been visible then as well. This dentist lack of professionalism and concern for his patient is reason enough not to go back to him. Find a new dentist and report this one. So sorry this happened, not all dentist are like this one. Good luck!

Additional information: I don't think your being overly sensitive or paranoid about your teeth or your dental situation, and this is "not" a common mistake. Find a new dentist, chalk this one up to just a bad dental experience being grateful that it could have been worse. Don't let this deter you from obtaining dental care elsewhere from an experienced, knowledgeable and compassionate professional that you can put your trust and faith in for many years to come. I wish you only the best in the future and for your dental care. Good luck!
