For everyone like me who was wondering:

Overview

The medical term for teeth grinding is bruxism (BRUK-siz-um), a condition in which you squeeze or rub your teeth together, also called clenching or grinding.

Interesting. I had to stop taking sertraline because of the bruxism. I've been debating going back though, it did wonders for my anxiety / mood.

PSA for anyone who's experienced bruxism (grinding, clenching...), for whatever reason:

Get a mouth guard at minimum and otherwise mitigate when viable.

Grinding now === root canals and/or removed teeth later. But not so much later that you can "deal with this later"...!!!

I second this. I shelled out the money for a custom fitted guard too. Mine was a bit over $400 after insurance. However, I strongly believe nothing over the counter comes close to it. At least, nothing I tried.

I honestly feel like not only sleep better with my guard, but I actually find myself having difficulties falling asleep without it now.

It can be worse than just worn down teeth. About 10 years ago now I awoke suddenly to an extremely loud cracking sound. It wasn’t until the next morning that I realised my jaw was now clicking every time I ate. It never went away. There’s something wrong with the joint but none of the specialists I’ve seen have been able to help.
