Snoring and Sleep Apnoea: How Your Dentist Can Help

Sleep Dentistry

Persistent snoring is not just a nuisance for the person sharing your bed — it can be a sign of obstructive sleep apnoea (OSA), a condition where the airway partially or fully collapses during sleep, interrupting breathing and preventing restful sleep. Many people are surprised to learn that their dentist can play a role in managing snoring and mild to moderate sleep apnoea using custom-fitted oral appliances. At Divine Dental Care on Wicklow Ave in Croydon, our team works alongside GPs and sleep specialists across the eastern suburbs to help patients explore whether a dental approach may be suitable for their situation.

What Is Obstructive Sleep Apnoea?

Obstructive sleep apnoea occurs when the muscles and soft tissues at the back of the throat relax during sleep and temporarily collapse inward, narrowing or completely blocking the airway. When this happens, breathing is interrupted — sometimes for 10 seconds or more — until the brain detects the drop in oxygen and briefly rouses the sleeper to reopen the airway. Most people have no memory of these micro-awakenings, but they prevent the deep, restorative stages of sleep the body needs.

OSA exists on a spectrum:

  • Simple snoring: Vibration of soft tissues during breathing, without significant airway obstruction. Disruptive for a partner, but generally not a health risk on its own.
  • Mild sleep apnoea: 5 to 14 breathing interruptions (apnoeas or hypopnoeas) per hour of sleep. May cause daytime tiredness and reduced concentration.
  • Moderate sleep apnoea: 15 to 29 events per hour. Associated with more noticeable daytime fatigue, mood changes, and potential impacts on cardiovascular health.
  • Severe sleep apnoea: 30 or more events per hour. Typically managed with CPAP (continuous positive airway pressure) therapy under a sleep physician's care.

It is estimated that a significant proportion of Australian adults may have some degree of OSA, with many cases undiagnosed. The condition is more common in men, in people who are overweight, and in those over 50 — though it can affect anyone, including younger adults and even children.

How Your Dentist Can Help

Dentists are uniquely positioned to identify signs of sleep-disordered breathing because they regularly examine the mouth, jaw, and throat structures. During a routine check-up at our Croydon practice, your dentist may notice indicators such as tooth grinding (bruxism), a scalloped tongue (impressions from pressing against the teeth), or a narrow airway — all of which can be associated with sleep apnoea.

For patients with mild to moderate OSA — or for those who cannot tolerate CPAP therapy — a custom-fitted oral appliance can be an effective alternative. The most common type is a mandibular advancement device (MAD), which gently holds the lower jaw in a slightly forward position during sleep. This repositioning helps keep the airway more open by preventing the soft tissues at the back of the throat from collapsing as readily.

Types of Dental Sleep Appliances

There are several types of oral devices your dentist may discuss with you, depending on your anatomy, the severity of your condition, and your comfort preferences:

  • Mandibular advancement splints (MAS): The most commonly prescribed dental sleep device. Custom-made from impressions of your teeth, these two-piece appliances hold the lower jaw forward by a precisely calibrated amount. Most modern designs allow some degree of jaw movement and mouth opening, which improves comfort.
  • Tongue-retaining devices: These use suction to hold the tongue in a forward position, preventing it from falling back and obstructing the airway. They may be suitable for patients who cannot tolerate jaw advancement or who have limited natural teeth.
  • Combination devices: Some appliances address both jaw and tongue positioning for a more tailored approach, particularly useful for patients whose obstruction involves multiple factors.

It is important to understand that oral appliances are generally recommended for mild to moderate sleep apnoea, or as a secondary option for patients with severe OSA who are unable to use CPAP. Their suitability varies from person to person, and a proper diagnosis — usually through a sleep study — should always precede treatment.

The Diagnosis and Treatment Process

Getting a dental sleep appliance is not a same-day process. It involves collaboration between your dentist, your GP, and often a sleep specialist. Here is what the pathway typically looks like:

  • Step 1 — Initial discussion: You raise your concerns about snoring or sleep quality with your dentist or GP. At Divine Dental Care, you can mention it during any routine appointment — our team is trained to ask the right follow-up questions.
  • Step 2 — Sleep study: If sleep apnoea is suspected, your GP or dentist will refer you for a sleep study (polysomnography). This can often be done at home with a portable monitoring device, rather than requiring an overnight stay at a sleep clinic. Sleep study providers service the Croydon and broader eastern Melbourne area.
  • Step 3 — Diagnosis and treatment plan: A sleep physician reviews the results and confirms the diagnosis. If a dental appliance is considered appropriate, your dentist receives the report and works with you to plan the device.
  • Step 4 — Impressions and fabrication: Your dentist takes precise impressions or digital scans of your teeth. The appliance is custom-manufactured in a dental laboratory to fit your mouth exactly.
  • Step 5 — Fitting and calibration: Once the device arrives, you return for a fitting appointment. The jaw advancement is adjusted incrementally — usually over several weeks — to find the position that provides the most benefit with the least discomfort.
  • Step 6 — Follow-up and monitoring: Regular follow-up appointments allow your dentist to check the fit, assess any changes to your teeth or bite, and confirm that the appliance is still functioning as intended. A follow-up sleep study may be recommended to verify that the device is effectively reducing apnoea events.

Signs You Should Raise With Your Dentist

Many people live with snoring or sleep apnoea symptoms for years before seeking help, often because they assume it is just a normal part of ageing or something they have to live with. If you or your partner have noticed any of the following, it is worth mentioning at your next appointment — or booking a dedicated consultation:

  • Loud or frequent snoring, particularly snoring that is audible from another room
  • Episodes where breathing appears to stop during sleep, often noticed by a partner
  • Gasping, choking, or snorting sounds during sleep
  • Waking up feeling unrefreshed despite a full night of sleep
  • Persistent daytime drowsiness, difficulty concentrating, or irritability
  • Morning headaches or waking with a very dry mouth or sore throat
  • Teeth grinding (bruxism) — your dentist may notice wear patterns on your teeth that suggest grinding during sleep

These symptoms do not automatically mean you have sleep apnoea, but they do warrant investigation. For residents across Croydon, Ringwood, Mooroolbark, Bayswater, and the surrounding eastern suburbs, your dentist can be the first step in identifying whether further assessment is needed.

Frequently Asked Questions

Do I need a referral from my GP to get a dental sleep appliance?

While you do not technically need a GP referral to see your dentist about snoring, a confirmed diagnosis of sleep apnoea — typically through a sleep study — is generally required before a dental appliance is prescribed. Your dentist can refer you for a sleep study, or you can arrange one through your GP.

Will my health fund cover a dental sleep appliance?

Some private health funds provide partial coverage for mandibular advancement splints under their major dental or appliance benefits. Coverage varies between funds and policy levels, so we recommend checking with your fund before proceeding. Our team can provide the relevant item numbers to help you confirm your entitlements.

Is a dental appliance as effective as CPAP?

For mild to moderate obstructive sleep apnoea, research suggests that custom-fitted oral appliances can be an effective treatment option. CPAP is generally considered more effective for severe cases. However, an oral appliance that is worn consistently every night may, in practice, deliver comparable outcomes to a CPAP machine that is used intermittently due to comfort issues. Your sleep physician and dentist can help you weigh the options.

Can children have sleep apnoea?

Yes. Sleep-disordered breathing can occur in children, often related to enlarged tonsils and adenoids, allergies, or jaw development issues. Signs in children may include snoring, restless sleep, mouth breathing, bedwetting, and difficulty concentrating at school. If you are concerned about your child's breathing during sleep, raise it with your dentist or GP.

How long does a dental sleep appliance last?

With proper care, a well-made mandibular advancement device can last several years. However, it should be checked regularly by your dentist to ensure the fit remains accurate and that no changes to your teeth or bite have occurred. The device may need adjustment or replacement over time as your dental situation evolves.

Will the appliance change my bite over time?

Some patients notice minor changes to their bite when using a mandibular advancement device over an extended period. This is one of the reasons regular follow-up appointments are important — your dentist can monitor for any changes and take appropriate action if needed. Morning jaw exercises, which your dentist can demonstrate, may help minimise bite changes.
