If you are a 'tongue base snorer', this means that your tongue is dropping to the back of your throat causing an obstruction. This will prevent you from breathing properly and very often your bed partner will notice 'pauses' in your breathing. This is due to the tongue blocking the airway, preventing the air from passing into your lungs. In trying to get past the obstruction the air vibrates the tongue or the throat tissues, causing snoring.
By using a Mandibular Advancement Device (MAD) you can gently bring your lower jaw forward and keep your tongue away from the back of your throat, thus preventing the obstruction.
