I ask as my partner gets severe debilitating pain that is increasingly frequent and increasingly worse and they keep being told it's likely TMD. But a mouthguard didn't help and the muscles exercises they were told to do have possibly even made it worse. Does TMD usually make people here unable to sleep through the night because the pain is so severe and be bed bound all day? Or that it's so severe they feel like (cw: allusions to suicide) they can't live their life anymore and want to do drastic things to end it?

I've been trying to be really supportive of them but I'm just not sure what to do anymore, neither a GP nor a dentist seems to consider it could be anything else? I found information about Atypical trigeminal neuralgia (ATN) today, but this hasn't ever been brought up so I'm not sure it's possible. I thought I'd check here if the severity they're experiencing is about what people here experience & expect?

(I also previously made a post in a dental subreddit asking for suggestions with a bit more background if people want it)
