Hmm I guess I'll try and see how it goes, any brand or type in particular u recommend?
Hmmmm interesting I googled about the mouth breather jaw and found a site that explain that airway may be obstructed due to it. Which leads to the brain forcing us to a lighter stage of sleep so that the muscles are able to grind and clench to push the jaw forward to reopen a collapsed airway. Also mentions it maybe a lead to sleep apnea

No wonder my mom says she can hear me grinding my teeth when im sleeping, this might be a lead for me now thank you bro!
