Sleep Apnea Frequently Asked Questions

OSA Risks Deer ParkWho gets Sleep Apnea?

Sleep apnea happens in all age groups and both sexes. However, is more common in men. At least 4% of middle-aged men and 2% of middle-aged women have sleep apnea with excessive daytime sleepiness. People who are most likely to have sleep apnea include:

  • Those who snore loudly (although you can snore and NOT have sleep apnea)
  • Have high blood pressure
  • Are overweight
  • Have a physical abnormality/obstruction in the nose, throat/or other parts of the upper airway

What’s the difference between Obstructive Sleep Apnea and snoring?

Snoring arises when the soft tissues in your throat and upper airway constrict and vibrate. The sound created is called snoring. When the soft tissues completely closes or obstructs the airway and prevents air from reaching your lungs, it is called Obstructive Sleep Apnea (OSA).

What are some signs that I may not be sleeping well or getting the rejuvenating aspects of sleep?

Continuous nights of improper sleep and breathing takes its toll on our quality of life and can include the following:

  • Always being tired, no energy
  • Easily irritated
  • Feeling of depression
  • Falling asleep at inappropriate times
  • Forgetfulness
  • Difficulty concentrating
  • Wake up with headache
  • Others are frustrated
  • Decreased sex drive

Regrettably, snoring and obstructive sleep apnea does not only affect the person with the problem. Anyone who has slept with a person who snores knows it can disrupt their sleep partner as well. This second-hand snoring can cause the bed partner to suffer the same daytime sleepiness problems that their snoring partner experiences which may lead to relationship disharmony and adverse health consequences.

What is Obstructive Sleep Apnea?

Obstructive Sleep Apnea is a sleep disorder with serious medical problems. Obstructive Sleep Apnea (OSA) occurs when the soft palate and tongue collapse onto the back of the throat. This blocks the air flow into the lungs. Lacking oxygen, the brain rouses the body from sleep with emergency signals. The sleeping person can stop breathing up to 300 times a night. This constant arousal to open the airway deprives the person of essential REM sleep and causing a list of problems associated with the chronic lack of sleep.

Symptoms of Obstructive Sleep Apnea are:

  • Loss of energy
  • Forgetfulness
  • Morning headaches
  • Trouble concentrating
  • Anxiety and depression

Untreated, chronic sleep apnea can cause:

  • High blood pressure
  • Cardiovascular disease
  • Memory problems
  • Weight gain
  • Impotency
  • Headaches
  • Impaired job performance
  • Motor Vehicle accidents


How severe is my OSA?

The degree of OSA is based on your AHI (Apnea Hyponea Index).  The AHI is determined during your over night sleep study. An apnea event is defined as lack of breathing for at least 10 seconds.  Hyponea is “shallow breathing” that leads to a reduction in airflow of greater than 50% for at least 10 seconds.  The total number of apnea and hyponea events that occurred during your PSG are added together and divided by the total amount of time slept to provide an “index” number.

  • AHI of:  5 to 14 is mild
  • AHI of:  15 to 30 is moderate
  • AHI of:  greater than 30 is severe

Why is it vital that Sleep Apnea be treated?

There are two reasons to treat snoring and apnea. The first is to improve your quality of life. Apnea and snoring can result in altered sleep patterns. Sleep is very important to the healing process and our ability to perform normally throughout the day. Snoring, of course, can be a nuisance to a bed partner as well.

The second reason is the relationship of apnea to serious medical conditions. Untreated sleep apnea can cause or worsen the following:

  • High blood pressure and other cardiovascular disease
  • Risk for heart attack
  • Risk for stroke
  • Pulmonary hypertension
  • Weight gain
  • Migraine headaches
  • Bruxism (teeth grinding)
  • Brain and cognitive changes
  • Morning headaches
  • Hyperactivity in children
  • Diabetes
  • Impotency and sexual dysfunction
  • Depression and anxiety
  • Acid reflux
  • Mood swings
  • Job impairment
  • Marital and other personal relations
  • The likelihood of motor vehicle accidents
  • Accidents at the workplace

Is Snoring Dangerous?

Snoring, a sign of Obstructive Sleep Apnea (OSA) can kill you. The struggle for breath and lack of breathing can result in high blood pressure. This can damage the walls of the carotid arteries and increase your risk of stroke.

How do oral appliances help me to stop snoring?

Nasal strips have been shown to improve flow of air just through the nose. However, snoring is not always nasal only. Usually it is a combination of nasal and oral constriction.

What is an Oral Appliance?

Oral appliances (OA) that help stop snoring and Obstructive Sleep Apnea are devices worn in the mouth similar to orthodontic retainers or sports mouth guards. There is no one particular appliance that will work for every patient. The devices are called Mandibular Advancement Device (MAD). Dr. Nugent will recommend the most appropriate MAD for you.

Advantages of using an Oral Appliance:

  • Treatment with oral appliances is reversible and non-invasive
  • Oral Appliances are small and convenient, making them easy to carry when traveling
  • Quiet
  • Easily adjustable
  • Easy to wear and more comfortable than CPAP, resulting in increased compliance
  • Sleep without being attached to a hose and machine


What is the difference between Oral Appliance, Mandibular Advancement Device and Oral Advancement Device?

Nothing. They are all the same thing with different names. They are all Dentist fabricated devices that pull the lower jar forward to prevent the collapse of the airway.

How does an Oral Appliance / Mandibular Advancement Devices work?

The device works by pulling your lower jaw forward. This does two things. 1) it prevents the soft tissue in the back of the throat and the tongue from collapsing over the airway 2) opens up the airway

Do oral appliances really work?

Yes! According to the studies, Oral Appliance Therapy (OAT) is 84.0% effective in treatment of non-severe Obstructive Sleep Apnea cases and 69.2% effective for severe cases. —Hoekema A. Oral-Appliance Therapy In Obstructive Sleep Apnea-Hypopnea Syndrome. A clinical study on therapeutic outcomes. 2008

The American Academy of Sleep Medicine published the “Practice Parameters for the Treatment of Snoring and Obstructive Sleep Apnea with Oral Appliances” in 2006.  “Oral appliances (OA) are indicated for use in patients with mild to moderate Obstructive Sleep Apnea (OSA) who prefer them to continuous positive airway pressure (CPAP) therapy, or who do not respond to, are not appropriate candidates for, or who fail treatment attempts with CPAP.  Until there is higher quality evidence to suggest efficacy, CPAP is indicated whenever possible for patients with severe OSA before considering OA’s.

Will an oral appliance will work for me?

No medical treatment including CPAP, surgery, or oral appliance therapy can guarantee that your apnea will be eliminated. The only way to treat apnea is to try one of these treatments. True success of any of these treatments can only be measured with a follow up Sleep Study. In the case of oral appliance therapy, the follow up sleep study is done while wearing the oral appliance.

  • Manual dexterity
  • Travel destinations
  • Preferred sleep positions
  • Oral cavity restrictions (anatomical structures)

  • By stabilizing the lower jaw and tongue
  • By repositioning the lower jaw, tongue, soft palate and uvula
  • By increasing the muscle tone of the tongue

With the above actions, the tissues and tongue are prevented from collapsing and occluding the airway. Therefore, air flows freely into the lungs and there is no vibrations of the soft tissue (known as snoring).

Does insurance cover the cost of Mandibular Advancement Therapy?

Most medical insurance policies will cover the Oral Device when Obstructive Sleep Apnea is diagnosed. For snoring with no OSA component, most policies do not currently pay for the oral device. Nevertheless, there is no question that for a snorer, mandibular advancement therapy is the best investment he/she can make in his/her health and domestic peacefulness.

Side Effects From Sleep Apnea

Are there any long-term health consequences Obstructive Sleep Apnea (OSA)?

Absolutely! In patients with untreated sleep apnea, the lowering of blood oxygen levels can contribute to the development of heart irregularities. Also, blood pressure will almost always be elevated due to the stress on the heart. Sleep apnea is known to be a cause of sudden death during sleep, although this is an uncommon occurrence. More heart consequences can be read in the Health Consequence section.

What will Dr. Nugent do if I need an oral appliance?

On your first visit after Obstructive Sleep Apnea is confirmed and the OSA can be treated with an oral appliance, Dr. Nugent will examine your teeth and mouth systematically. If it is determined that Mandibular Advancement treatment is the best treatment option for you, dental impressions will be taken. These impressions are used by a dental lab to fabricate your custom made oral appliance. Once you have been wearing your appliance regularly and symptoms such as snoring or daytime sleepiness has been reduced, Dr. Nugent will again initiate a Home Sleep Study to determine how effective the appliance is for you. Regular recall visits to our office is vital to maintain your oral appliance over time.

What are the side effects associated with Mandibular Advancement Therapy?

  • Excessive salivation or dryness
  • Morning soreness in the teeth or jaw muscles
  • Minor tooth movements

Is a Mandibular Advancement Device more effective than CPAP?

A CPAP (Continuous Positive Air Pressure) is an air pump that delivers controlled air pressure through a hose and into a face mask. It is very effective for the 60-70% of people who can tolerate it. The 30-40% of people simply cannot tolerate the CPAP for many reasons. In many cases the Mandibular Advancement Device has been as effective as CPAP without discomfort or inconvenience.

I can’t use my CPAP. Can I use an oral appliance instead?

CPAP is the gold standard for treating sleep apnea but unfortunately many people find that they can’t tolerate wearing it. For persons with severe apnea, though CPAP is the treatment of choice, oral appliance therapy if recommended if the patient can’t tolerate their CPAP. For persons with mild to moderate apnea an appliance will in most cases eliminate the need to use their CPAP machine
