For decades in the sleep medicine field, we've been using chin straps. just like a elastic bandost at night. For people who are snoring that don't that where it's just mild snoring and they don't have sleep apnea um or their sleep apnea is mild or their sleep apnea is due to them opening their mouth at night and their tongue falling back and they can breathe through their nose. Okay, chin straps have been great.
