An antisnoring device is found in a U-shaped, wedge-like intraoral training appliance that separates the teeth, provides additional intraoral space for the tongue and retrains as it tones up the muscles of degletition and mastication while the user is in a sleep induced state. Thereby resulting in a more open airway space facilitating the improvement of snoring, of obstructive sleep apnea and nocturnal occlusal trauma.
