Mouth Open<br>At night time, my mouth was falling open frequently. I purchased a mouth guard in the hopes it would help. In the middle of the night, I awoke with pain in my jaw. I tried changing position several times, to no avail. I finally removed the guard and gave up.
The mouth guard worked very well for this person.
