I wasn't aware that initially I would have to retrain myself to speak, because I found I spoke with a lisp when I first had my denture in. Now I find that I speak with a lisp when my denture is out, so I have to keep it in most of the time, and also things taste different when you first have the denture fitted, and you get used to temperatures being different as well, so it's a lot of retraining to do in temperature, and taste, and actual speaking. But once you get through it, and you will get through it, it's all ok.
