Important: Snoring can sometimes be a sign of obstructive sleep apnea. Over-the-counter anti-snoring mouthpieces are not a substitute for a medical diagnosis. If you wake up gasping, have witnessed pauses in breathing, suspect sleep apnea, have significant dental problems, or have persistent jaw/TMJ pain, talk with a qualified healthcare or dental professional before using an oral appliance.
