Sleep Dentistry

Sleep disordered breathing

Sleep Dentistry

Sleep disorders and sleep deprivation can affect your health and quality of life. It can cause poor work performance, put you at risk for accidents, and affect your mood.

When you are sleeping, your body recovers from daily stress. However, oxygen deprivation and brain arousals, during sleep, prevent your body from recovering. The only way to find out if you have sleep apnea or a sleep disorder is to undergo a sleep test. If your physician or dentist suspects you have a sleep disorder, he or she will refer you to a sleep clinic and have you tested under the supervision of a sleep specialist.

Common Sleep Breathing Disorders

Benign snoring

A mild form of airway obstruction that likely has no impact on overall health, other then possibly disturbing one’s partner’s sleep.

Upper Airway Resistance Syndrome (UARS)

Increased breathing effort needed to get past the resistance in the upper airway. Due to the need for increased respiratory effort, the brain has to arouse itself from deeper stages of sleep. This interrupts the proper sleep cycle and interferes with the brain’s efforts to repair and restore itself. UARS can lead to Obstructive Sleep Apnea if remains unmanaged.

Sleep Apnea

Involves apneas (pause in breathing) and hypopneas (reduction in breathing), where breathing repeatedly stops for 10 seconds or more and O2 saturation drops by 3% or more.

Central: is where the brain doesn’t send proper signals to the muscles that control your breathing during sleep
Obstructive: involves an obstruction in the upper airway that prevents one to take a breath during sleep
Mixed: both central and obstructive apneas are involved

What Causes Sleep Breathing Disorders?

Genetic/hereditary

Gender (more common in men)
Age
Family history

Lifestyle

Excess weight
Large neck circumference
Alcohol and sedative use
Smoking

Developmental

Narrowed airways
Limited tongue space
Poor tongue function
Retruded jaw position
Enlarged tonsils and adenoids
Nasal congestion/obstruction
Deviated septum
Enlarged nasal turbinates

What are the risks?

We can affect life-style and developmental factors because they cause lack of space in your airway. For example, losing weight or correcting a deviated septum can improve the physical space in your airway.

There are two types of sleep apnea, Obstructive Sleep Apnea (OSA) and Upper Airway Resistance Syndrome (UARS). Both are dangerous conditions that can shorten your life and predispose you to chronic conditions affecting quality of life. Some of the potential risks include:

High blood pressure (hypertension)
Risk of heart attack
Risk of stroke
Diabetes
Obesity
Impotence

How can sleep dentistry help?

Often, one of the first signs of sleep disordered breathing is toothgrinding and dentists can detect this by assessing the wear of your teeth. Grinding can speed up wear and tear of your teeth, jaw muscles and joints. While tooth grinding may be the first sign, it isn’t the only sign of OSA you may have related to your oral health. Part of our semi-annual exam, we assess for certain dental signs of sleep disordered breathing, such as:

Under-developed upper and lower jaws
Tooth crowding
Poor tongue tone and posture
Restricted airways in the throat
Enlarged tonsils
Scalloped edges around your tongue

We also use questionnaires that help us determine level of daytime fatigue, snoring and your overall quality of sleep.

What are the treatment options?

There are two approaches to the treatment of sleep apnea. The first involves reducing the obstruction itself. The second is to by-pass the existing obstruction. Common therapies include:

Reducing the obstruction

Life-style changes
- weight loss (exercise/diet)
- smoking cessation
- limiting alcohol use
Myofunctional Therapy
Dental Orthopedics and Orthodontics
Laser therapy
Surgery

By-passing the obstruction

CPAP (considered the Gold Standard to OSA management today)
Oral Appliances maintaining forward jaw position
Positional therapy – sleeping propped up on the pillow; or sleeping on the side
