It worked quite well for my Dad, until one of this occasional gum/jaw infections shifted his teeth slightly, so now the dental splint doesn’t fit. I don’t recall him having problems getting used to it. Caring for it is similar to dentures or a retainer: brush and rinse your teeth before putting it in for the night, brush/soak it in the morning.
The fun part, as I remember correctly, was getting insurance to pay for it. Medical said it was a dental device. Dental said it was a medical device. Eventually insurance paid for it, but I can’t remember which coverage did.
