I don't grind my teeth but I clench them and my jaw throughout the night and am constantly getting horrible headaches form it. Instead of paying $400 to my dentist I figure I would try this first and I am so glad I did. I followed the directions exactly and it molded to my teeth perfectly. The only down side is it does feel a bit bulky in my mouth but nothing I can't get use to.
Well, the guard did stop me from grinding my teeth....... problem is as soon as I started wearing it I started snoring. I've never snored my entire life. After a bit of research I found when you sleep on your back it's because your lower jaw falls down (not open but twards the back of your head)partally blocking the airway causing a snore. When I ground my teeth it kept my jaw from falling. With the guard only being fitted on the top row of teeth & partially because it is a bit bulky & partially because I am not grinding anymore, my mouth hangs open & my jaw drops & I snore. Finally my husband is getting a taste of his own medicine. If you're a side sleeper this would be perfect, it's really easy to fit to your mouth & seems to work very well @ stoping the grinding.
