Dental treatment options
Below, we explain what oral appliance therapy (OAT) is, the different
device options, and when OAT may be an option for treating obstructive
sleep apnea (OSA).
What is Oral Appliance Therapy (OAT)?
Oral appliance therapy involves using a custom dental device to help
keep the airway open.9 There are two main types of oral
devices:9
- Mandibular advancement devices (MADs). These are
designed to move the lower jaw slightly forward to help open the airway.
They are custom-made for a comfortable fit and can be adjusted if
needed.
- Tongue-retaining devices (TRDs). These are
designed to hold the tongue forward to prevent it from blocking the
airway.
A dentist can help determine which of these devices may be the right
choice for you and ensure it’s properly fitted. While oral devices may
be an option for people with mild to moderate obstructive sleep apnea,
9 continuous positive airway pressure (CPAP) therapy remains
the most effective sleep apnea treatment.8 CPAP therapy uses
a mask that fits over your nose and/or mouth, connected to a machine
that delivers a steady flow of air. This air is designed to keep your
airway open and reduce breathing pauses while you sleep.7
How effective are dental appliances?
Dental appliances tend to work well for people with mild to moderate
obstructive sleep apnea.9 The severity of sleep apnea is
determined by how many breathing interruptions occur per hour of sleep —
often referred to as AHI (apnea-hypopnea index). Obstructive sleep apnea
is classified into:2
- Mild: 5 to 14 breathing events per hour
- Moderate: 15 to 29 breathing events per
hour
- Severe: 30 or more breathing events per
hour
The success of a dental appliance in treating OSA depends on your
body structure, the severity of your sleep apnea, and how consistently
you use the device.9 CPAP is the most effective treatment for
OSA, especially severe OSA,8 and any treatment decision —
including whether to use a dental appliance — should be made under the
guidance of a doctor. A doctor may also recommend follow-up sleep
studies to assess the effectiveness of a dental appliance.
Severe sleep apnea can have serious health consequences if left
untreated. If you think you may have severe sleep apnea, see a doctor
for diagnosis and treatment.
What to consider when treating sleep apnea with a dental appliance
In addition to discussing your situation and care needs with a
doctor, you may also need to consider the following factors when
deciding whether a dental appliance is right for you:
- Costs. Dental appliances can be expensive, and
insurance coverage can vary widely. Check with your insurance beforehand
to find out how much you’re likely to pay for a dental
appliance.
- Side effects. Not everyone can tolerate a dental
appliance. Some people experience side effects like jaw pain, changes in
their bite, and dry mouth.
- Adaptation. It can take some time to adjust to
wearing a dental appliance while sleeping. If you find that it’s
interrupting your sleep and not becoming more comfortable over time,
consider discussing other treatment options like continuous positive
airway pressure (CPAP) therapy with your doctor.
- Maintenance. Dental appliances are subject to
wear and tear, and they will need to be replaced eventually. It’s
important to have regular follow-ups with your dentist to ensure the
device is working as intended and safe to use.
Your doctor may recommend periodic sleep studies to assess your OSA
symptoms and evaluate the effectiveness of your treatment. If your sleep
apnea doesn’t improve with a dental appliance, changing to CPAP therapy
may lead to better results.15
Lifestyle changes to help improve results
Making lifestyle changes in addition to using a dental appliance or
CPAP therapy for OSA may help improve your results. Your dentist may
provide specific recommendations based on your situation and medical
history, but some of the most helpful lifestyle changes
include:11
- Weight management. Losing even a small amount of
weight can help reduce symptoms of OSA.
- Sleeping on your side. Sleeping on your back
often worsens OSA symptoms, so changing your sleeping position to your
side or elevating your head, such as with a wedge pillow, can
help.
- Cutting back on alcohol and smoking. Drinking
alcohol or using tobacco products is a risk factor for OSA, and quitting
or cutting back can help reduce symptoms.
- Focusing on a nutritional diet. Eating the right
foods can play a role in weight management and can promote other health
benefits. Prioritizing plant-based foods, such as fresh fruits and
vegetables, and limiting meat and dairy products may help decrease the
severity and symptoms of OSA.
- Exercising. Regularly moving your body, such as
walking or swimming, can improve overall health and potentially decrease
the severity of obstructive sleep apnea (OSA), even if you don’t lose
weight. Myofunctional therapy, which involves performing mouth and face
exercises daily, has also been shown to reduce snoring and improve
overall quality of life.
