Posting again because I need to make a decision about this and I can't decide. I had a painful wisdom tooth coming through, went to the dentist and he said it was fine. Turns out he was right, it's not sore anymore.
He also said that I needed another tooth out, one that has never given me any trouble. Apparently it is at a weird angle and I'm, in the dentist's words, "eating myself".
I've had a good poke around and a look with a mirror thing and I'm SURE the tooth is not touching my cheek or my bottom gum, even when I have my teeth clenched together. It's not sore and it never has been.
I'm slightly concerned that the tooth doesn't need to come out and the dentist just wants the money ($160 in NZ, no NHS). He says it's an emergency, but he has booked me in for the end of the month so it can't be that urgent.
Should I call him and get him to explain exactly why it needs to come out? Just go through with it? Or not? I don't know! I just think the tooth is fine where it is!
