My dad grinds, my sister grinds. I grind my teeth so hard that I have cracked and broken them (heard: collective cringe). My dentist said last time I was in his office "That's amazing! Can I take some photos and post this on our website" after I broke a diamond centered crown with my night grinding. (yes I broke my tooth twice, the original AND the diamond centered crown that replaced it).
So I wear a night guard. A thick, plastic, protective mold that fits on my top teeth.
If I put on shiny shorts and and a pair of gloves I could be a boxer.
