Just had some dental work done. Seems when mt arthritis is real painful I grind my teeth. So much so I had no enamel left on my top two front teeth. He filled them & strongly recommended a night guard (again). Used it last night for the first time. It kinda felt odd, had to sleep with a tissue. That thing made me drool. Will I get used to the guard, I can see it spending it's life in a cup.grin.
