Boil=and-bite only provides cushion between teeth. Sleep apnea mouth guards are designed to thrust the jaw forward, so as to mechanically assist in keeping the airway open. They're so very different in effect and structure that if you feel you're benefiting from a boil-and-bite, you've almost certainly mis-attributed something somewhere.

Not necessarily. Boil & bite mouthguards can help you keep your mouth closed while you sleep, which might be enough to fix your breathing in some cases.

My boil and bite has a hex key lower jaw adjustment same as OSA nightguards, many (but not all) of them do
