To get you started, Dr. Kara will examine your mouth and ask you some questions related to your health and sleep history. A sleep study may be required to determine if you are a candidate for the MicrO2 appliance.


If you snore or have been diagnosed with Obstructive Sleep Apnea, the MicrO2 device will assist you in waking with a better sense of rest and give you the energy you need to enjoy your day. The MicrO2 is designed to be the smallest and most comfortable custom made jaw advancement device available. It's lingual-free design is intended to offer the most tongue-space, and the ability to open and close during wear. Please contact our office if you think a MicrO2 appliance is right for you. 

How we can help you

Research studies have shown that using an oral appliance such as the MicrO2 can assist in alleviating symptoms of Obstructive Sleep Apnea and snoring by holding your lower jaw forward during sleep. This gentle protruding of the lower jaw allows your airway to open more and assists you in breathing without throat or tongue interference. The use of MicO2 can enhance the quality of your sleep as well as lessen daytime sleepiness, irritability, sluggish feelings, headaches, and other serious health problems that come from sleep-disordered breathing. In addition, your bed partner may experience and enjoy more quiet nights of sleep. 

Improve your life

Your mouth and throat tissues become relaxed when you fall asleep, causing them to fall toward your throat. This creates crowding of the throat by the tongue and soft palate, resulting in a partially blocked airway. Air passing through this narrow airway causes your throat tissues to vibrate. This is what creates the snoring sound. 

What causes snoring?

For some people, when they fall asleep, the tongue and soft tissues obstruct air from entering their lungs. If the amount of oxygen in your blood drops too low because of this, your brain sends a message to your body to unblock the airway. Your body's reaction is to tighten your throat muscles with a loud gasp or snort, which means you partially awaken. The airflow to the body begins again after this reflex.
