kat, I think my dentist recently recommended something like that to keep me from chipping my teeth in my sleep. I followed links to the dental sleep med site, but it did not show or describe exactly what the dental apnea treatment is. If it is like the one recommended to me, it fits over just the front teeth to keep the bite from completely coming together while sleeping. Since about '98, I've had my front teeth chip three times in my sleep.
