I've been grinding my teeth like mad since my second wisdom tooth extraction. I was waking up in the morning feeling like I'd been chewing rocks all night. And it's segued nicely into grinding my teeth because of the pain on this tooth that requires a root canal. I am megadosing on anti-inflammatories before bed tonight.
Ask your dentist for a bite plane. You're going to need a lot of dental work in the future if you keep grinding your teeth.
I had a nightguard, but my bite is inconsistent so it didn't fit for very long. Our strategy this time was to fix all the things blatantly wrong in my mouth and then worry about the grinding. I need ortho pretty badly, but my jaw is fucked from a car accident years ago, so I may need to do something with my jaw first. Something surgical.
