The Lamberg SleepWell Appliance

The Lamberg SleepWell Appliance
The Lamberg SleepWell Appliance can improve your breathing while you sleep.

In 2004, a friend of Dr. Lamberg requested an oral appliance. His friend had patients who struggled with sleep apnea and related symptoms. Dr. Lamberg's friend was so impressed with the results of the oral appliance that he began referring more and more patients to Dr. Lamberg. In 2013, the Lamberg SleepWell Appliance became an FDA-approved treatment method for sleep apnea and other forms of sleep disordered breathing.

The Lamberg SleepWell Appliance holds the jaw and tongue in a comfortable, forward position to keep the airway open during sleep. By adjusting the position of the jaw and tightening the tissues in the upper airway, this device stops snoring and helps you get a better night's sleep. If you struggle with sleep apnea or regularly snore, you may find relief with Dr. Lamberg's innovative appliance.
