I have the same problems and yes I have read up on it that’s part of fibro

Yes started this year..no answers from dentist saying it's fibromyalgia..
A gp said trigeminal neuralgia..gave me gabapentin..it helps a lot..not 100, however can tolerate the pain now.

All the time not comes out on x ray aswell

Yes, it likely is a symptom of fibromyalgia. I get random and roving tooth pain. Nothing shows up on x-rays.

Hi there, I have lost 2 teeth from the pain of fibromyalgia...the pain from my migraine headaches and the pain in my neck and collar bones from a car accident 40 years ago, now all these nerves in body have caused 24 hour pain=fibromyalgia. I was diagnosed in 2018 and was told my teeth pain is from TMJ which is linked to fibromyalgia. You may want to wear a teeth/jaw guard, like the hockey players wear...as for the pain, I don't eat anything too hard(hard candy, potato chips) and try not to grind my teeth when in pain.
Talk to your dentist for more ideas..
Take care
