Hello all, yesterday I went to the dentist very nervous and hyped dentist was very understand. Anyway, I needed a filling on the back molar so he said I will just numb you up (hate the injection) after he kept on saying can you feel your bottom lip going a bit numb, well I couldn't but was so strung up with anxiety could hardly think so we waited longer. In the end I said to him why don't you start and I will raise my hand if I feel pain. Got through till near the end then I felt him close to the nerve and he stopped. So here it is after when it was all done I noticed that I was speaking ok and that I was not numb at all !!!! I said to him look I am not numb ! his answer was sometimes it happens with the back lower teeth. At this point I just wanted to get out. After thinking about it all this was a private dentist , also what I want to know all the stuff he injected in my gum where did it go ?....has worried me for the future.
