Have been referred to oral surgery clinic by dentist [1 week ago ] for an ulcer on back lower gum. Appt made for 1 week from now. Wear dentures and have been a heavy smoker for 50 years [now aged 72 ] Absolutely terrified, tearful and depressed. Guilt over my smoking habits and don`t know who to talk to. gave up smoking over 4 years ago--probably too late. have googled the condition and treatment sounds terrifying. Totally consumed with fear and find it hard to function.
