Im just curious. I have filings along my bottom gum lines from teeth grinding. Been doing it for 11yrs now, that I know of. It was the dentist that told me this erosion is from grinding, and the grinding even wakes me up sometimes. I will wake up and my teeth are heavily presssed together. I have even woke up while grinding. He, explained to me it's like a ton (or something) weight that is grinding when the jaw is locked like this, and it damages the teeth at the gum line from moving them back and forth.
He did tell me to buy a guard, and I use it sometimes, but mostly I can't be bothered wearing it.
Does anyone else have this problem?
