Boy is this ever timely.
I was a teeth-grinder from way back. I went through a number of dental appliances and ended up with over $10,000 of crown work three years ago plus a new acrylic guard. Went On CPAP 6 months back and was using the guard but when I switched to a nasal pillow mask, I stopped using the guard to avoid mouth breathing. That worked for a while but I began to notice the telltail evidence of grinding - stiff or sore jaw muscles - a feeling like I had been chewing five pieces of bubblegum for hours.
My brain must have recognized this (sometimes my brain is smarter than me
) and two nights ago - evidence of mouth breathing started up. Tonight is dental guard and blue tape for me.
Not sure if you could damage a tooth in such a short time but I suppose that if it were already cracked or damaged, it could have been just enough. Ow!
