Broken Teeth: Your fear has kept you away from proper care for a long time. You'll need a one on one consultation with a well respected dentist who will examine you, take radiographs, and advise you of what you need. This will not hurt, so relax. If you want, arrangements can be make to sedate you for your care. But you have to make the first step and call otherwise risk losing your teeth.

Back teeth: Please seek professional care. Dentist's are trained to help you, as comfortably as possible. If your teeth are "fading away" you probably have extensive decay, and that infection is causing harm to other organ systems, such as heart, brain, kidney, etc.Take the 1st stem. See a Dentist for a complete examination and imaging. Then the Dentist can help you along the path to optimum health.
