Can grinding teeth make them disappear?

Yes: I've seen it happen. Consult with a dentist if you grind to see what steps can be taken to protect your teeth.

Absolutely !: Stress resulting in clenching and grinding of your teeth. Eating a very coarse food diet, harmful habits (such as chewing on pens & pencils) chewing gum for hours (try to spit out as soon as the flavor is gone - about 5 minute) all can lead to worn down teeth. Talk to your dentist for answers and solutions.

See a specialist: Bruxism, or grinding of the teeth at night can be devastating to the teeth, muscles, the jaw joints and your overall health. It can wear down the teeth, affecting a domino effect of gum disease, loose teeth, shifting and moving of the teeth, headaches, on and on. It is not something that should be ignored or put off. See a dentist asap to avoid problems later.
