That's what could eventually happen, not to scare you but to forewarn you.
I grind my teeth as well. At night, too much when I eat/chew gum, when I get stressed... so my dentist made me 3 different mouth guards. One for night-time (can't talk well with it), and two that are "weaker" and you can wear doing other activities and in public because they're harder to see (essentially transparent). Quite useful for the time I was using them, they saved my teeth unnecessary agony because I have sensitive teeth.
