What is the primary purpose of a mandibular advancement device (MAD)?

The primary purpose of a mandibular advancement device (MAD) is to increase upper airway volume. This type of device is commonly used in the treatment of obstructive sleep apnea and snoring. By positioning the lower jaw (mandible) forward relative to the upper jaw, a MAD helps to prevent the collapse of the airway during sleep. This advancement creates more space for air to flow freely, thereby reducing the incidents of airway obstruction.

In comparison to the other options, the device is not designed to specifically address jaw clenching, enhance saliva production, or decrease tooth sensitivity. While it may have some indirect effects on these areas due to improved overall oral health and airflow, its primary function remains focused on maintaining an open airway and promoting better breathing during sleep.
