It was a fw years ago when I developed the most excruciating pain on the right side of my face. Non stop-agonizing-unrelenting-and no pain med helped. Went weeks - thought it must be teeth - finally went to dentist who said it was not teeth infection but neuralgia pain (forget)

But, here's what worked! He fitted me with a plastic thing that sets on my front teeth - prevents grinding of teeth etc - and in 1 day the pain had decreased and within three days all pain had ceased.

I wish I could explain better as he was very knowledgeable about the pain and triggers. They have full mouth pieces but the smaller front teeth one was cheaper so I choose that.

However, it is also small enough that I could wiggle it off and swallow it in my sleep - so I would HIGHLY suggest for anyone to go the extra dollar amount and get the full mouth piece one.

I only wear my small one during the day when I am awake.

I haven't had any further problems since I got the thing.

A dentist has to have this item fitted to your teeth/mouth.

Sorry-its all I can remember. Hope this helps someone.
