A dentist being interviewd today said she and many dentists won't take them on as patients. She also said that if she carried out filing teeth down to stumps or points to fit crowns etc, she would be struck off.
Imagine the pain you must go through having that work, they must be mad!
My four front teeth were drilled right down before I had posts put into them for when the crowns were fitted. Years later, I knocked them out when I face planted the street Ooop North.
