how long do I have to wait after an exraction to have dental implants. I had four teeth removed about a month age and I would really like to have some implants as I can not cope with a denture. My tongue is now covered with small ulcers which I am using an appropriate mouth wash but I was told to keep the denture in place which is really uncomfortable. Most of my back teeth are now missing which means eating is a real problem for me. I was given a partial upper denture which I cannot wear because it makes me gag and a partial lower denture which is causing the ulcers on my tongue. I was told that I have to persevere with the dentures but I can not handle it. I am very aware of my teeth and am becoming very depressed over the lack of my back teeth. I have had 7 crowns put onto my front teeth but I have had a lower front tooth extraced hence the denture. Please can you help or give me advice what to do. I live in Aberdeen. Thank you
