I've also had teeth breaking. Old fillings falling out and more cavities. Never thought it about being related till a cousin who has nerve issues due to something else had dental surgery to remove teeth cause they said the nerves were dead so I thought I'd check on here to see if anyone else has

I sleep with a mouth guard which helps with that.

As far as waking up in a mood goes, my family has learned to give me a wide berth and sometimes call me "Grumpy Guss".

I may have 2 teeth without cavities (which have appeared this year) although I brush regularly. My FOOD & drink have to he heated to 74 degrees to not hurt my teeth. Chewing anything but mashed potatoes hurts as well, so I guess teeth issues must be on the ms list also

Yes mine are cracking splitting and breaking. They use to be great now not so much
