hi, i have type 1 diabetes, i have really bad dental problems which is getting me down, my dentist makes me feel dirty and embarrassed, i need help as my teeth are turning black at the back, i am 36, it is really starting to depress me, i would like to have implants but the cost is to expensive, does anyone know of a dentist where the cost is not so expensive, i live in london, any help would be appreciated. thank you ashley.
