I have a mouth guard for my top teeth. It was made by my previous dentist to keep me from grinding my bottom front teeth into my top front teeth.
The I switched dentists. Brought in the mouth guard. The new dentist asks me IF I have ever been tested for sleep apnea?
I asked why. He asks me IF I snore. Yes, why? he responds that people who grind their teeth and snore typically(75% of the time) also have sleep apnea. He then advised I get tested.
There are mouth guards that go on your top AND bottom teeth. They are connected so it pushes your bottom teeth out so that your airway remains open.
The grinding of your teeth in my case is a symptom of my body/mouth trying to keep my airway open when I am sleeping.
I have one similar to yous. I t costs $550.00. My insurance covered it but my dentist had to appeal to my insurance. I hate it. Sometimes I must take it out in my sleep.. I find it in my bed.
