Has a dentist ever asked or told you you grind your teeth? You might want to ask your dentist to make you a custom bite guard.
I never had a pacifier when i was a baby (or so i was told), so when i got my night mouth guard a few years ago, it was primal! I was like, so THATS what ive been missing all these years. I used to gnaw on the tips of Bic pen caps, coffee stirrers, Life Savers candies, gum - so yeah my teeth are a wreck.
