Sleep apnoea is a common yet serious sleep disorder affecting millions of Australians, significantly impacting their health and quality of life. Specifically, obstructive sleep apnoea (OSA) occurs when throat muscles intermittently relax and block the airway during sleep, causing breathing to repeatedly stop and start. Despite its prevalence, many individuals remain unaware they have it, highlighting the importance of understanding the connection between oral health and sleep apnoea for early detection and treatment.

Understanding Sleep Apnoea: Symptoms You Shouldn't Ignore

Recognising sleep apnoea early can help you seek assessment sooner. Chronic loud snoring is one of the most noticeable symptoms and often indicates airway obstruction. Another common sign is observed pauses in breathing, frequently reported by partners or family members who notice episodes where breathing briefly stops during sleep. Additionally, excessive daytime fatigue can signal disrupted sleep quality, even if you think you’re getting adequate rest at night.

Other symptoms such as morning headaches, irritability, mood swings, and difficulty concentrating can also be indicators. These issues often result from inadequate oxygen intake and fragmented sleep.

Identifying these symptoms early is important. Sleep apnoea is a medical condition, so if you experience these symptoms, promptly consult a health professional.

How Dental Health Reflects Sleep Apnoea

Your oral health can reveal signs that may be associated with sleep apnoea, making dentists a useful resource for early detection. Several oral health indicators are associated with sleep apnoea:

‍

Teeth Grinding (Bruxism)

Teeth grinding, or bruxism, often occurs during sleep as the body’s subconscious attempt to reopen a partially blocked airway. This frequent grinding places excessive stress on teeth, causing noticeable wear, cracks, and even structural damage. According to a study published in the Journal of Clinical Sleep Medicine, bruxism is more prevalent among individuals diagnosed with obstructive sleep apnoea.

‍

Enamel Erosion and Tooth Sensitivity

Continuous nighttime grinding and clenching related to obstructed breathing can lead to the erosion of tooth enamel. This enamel loss can increase the risk of tooth sensitivity, decay, and cavities, often presenting noticeable symptoms such as discomfort when consuming hot, cold, or sweet foods and beverages.

‍

Tongue Indentations and Scalloping

Dentists frequently observe scalloping or indentations along the edges of the tongue, indicating repeated pressure against the teeth. This sign suggests the tongue repeatedly moves forward in attempts to clear the airway during obstructed breathing events.

‍

Jaw Structure and Alignment

A small or recessed jaw (retrognathia) can predispose individuals to sleep apnoea by physically restricting airway space. Dentists can identify these anatomical features during regular examinations, which may support early intervention.

Regular dental visits offer valuable opportunities for early detection of sleep apnoea. Dentists are trained to recognise these subtle signs, and can play a role in the early identification of the condition.

The Role of Dental Professionals in Sleep Apnoea Diagnosis

Dentists are well positioned to identify signs of sleep apnoea during routine dental visits. They perform comprehensive oral examinations, carefully looking for subtle signs linked to sleep disorders. In many practices, including Skye Dental, screening questionnaires are used to evaluate the likelihood of sleep apnoea. These simple tools help guide patients towards further sleep assessments when necessary.

Dentists also work closely with sleep physicians, so patients receive a multidisciplinary approach with diagnosis and management tailored to their needs.

Dental Treatments for Sleep Apnoea: Oral Appliance Therapy

When obstructive sleep apnoea is diagnosed, dental professionals may offer non-invasive options such as oral appliance therapy. One option is the Mandibular Advancement Splint (MAS). This custom-made oral device works by gently repositioning your lower jaw forward, helping to keep your airway open through the night and reduce apnoea episodes.

Custom-fitted MAS devices are typically preferred over generic, over-the-counter alternatives for comfort, fit, and patient compliance. Oral devices also offer a practical alternative for patients who find continuous positive airway pressure (CPAP) machines uncomfortable or difficult to use consistently.

Oral devices may help manage symptoms for some patients, but outcomes depend on accurate diagnosis, precise fitting, and patient adherence to regular use.
