Since I was a kid, I've gone through periods where I grind and Nash my teeth in my sleep. My dentist has said I've caused stress fractures to my teeth as a result 😬
I had a proper mouth guard made at the dentist that, admittedly was better than the do it yourself ones Ive bough off amazon or from the drug store, but that was still annoying solid, hard, not really saving my jaw from pain. Thankfully (??) my dog chewed it up one day when I forgot to put it away and she was annoyed I'd gone to work. Since I couldn't afford another one and I'd give myself repeated migraines from the constant grinding and mashing of said teeth, I had to find an alternative. Enter these little guys. They are so comfy, you can chose to put them on your top teeth, or bottom, depending on what's more comfortable. I tried both but prefer the bottom sincs gravity keeps them in place better. First night with it I fell asleep no problems and woke up paj free. The next time I had a dream I was eating the most delicious Ginger cookie and woke up chewing the life out of this thing, not as tasty sadly, but it survived my sleep laden attempts to devour it, stayed in place, and did its thing. If only it was cookie flavoured....
