Happy Sleep is clinically proven to shush a snorer, more than enough to not wake a sleep partner. But unlike traditional snoring aids, whose bulky chin straps and jaw protruding designs are notorious for causing jaw, teeth, and gum pain, Happy Sleep is built for comfort. Happy Sleep’s soft, flexible, mouthpiece fits snug into the mouth, straight out of the box. Inside the mouth, the splint advances the jaw only minimally, avoiding discomfort and permanent changes to the bite. Outside the mouth, the innovative support flap holds the jaw together, preventing the lower jaw from falling and taking the mouthpiece with it. These features combine then to allow the breathing airway to do its job, enhancing airflow in through the nose, and reducing noise out from the mouth. Giving you a quiet comfortable sleep.
