Sleep apnea is a condition that results in awakening during the middle of the night, gasping for breath. It is caused when the airway is obstructed by the tongue. It is sometimes accompanied by snoring but is a far more serious problem. Sufferers can be treated wearing a type of mouthpiece at bedtime, that is comfortably worn while sleeping. Not only will it prevent the closing of the airway, but it will eliminate the snoring as well if that is present. It works by slightly changing the jaw position. The custom fitted applicance is made from an impression taken in the dental office and can be ready to wear in a week.
