Once again, the dentist said I have evidence of grinding and he recommended I buy and use a mouth guard. I ignored him from the last ten times he or his predecessor dentists said this. But this time I asked him to show me. He used his camera (ten year old technology) and showed me the grinded places on my teeth. They were on the upper edged of my lower incisors. In other words, a mouth guard would have done zero good. Epiphany happens. That grinding motion happens when i am awake. It is caused by me chewing my fingernails. Something I have done for 50 years. This might have been good advice 50 years ago. Or even 20 years ago. A bit late now. And the dentist advice was totally wrong, useless and a waste of about $200 (if I took it). They were wrong.
I am posting this here so that the internet will now know there is a danger to chewing fingernails besides being a social pariah. It harms your teeth. learn from my mistakes. Tell your kids that they don’t want to end up like this:
