What is sleep disordered breathing?

Sleep disordered breathing (SDB) refers to a group of conditions where abnormal breathing patterns occur during sleep, including the most common, obstructive sleep apnoea (OSA). Individuals with SDB often experience frequent pauses in breathing, snoring, and poor sleep quality, which can lead to serious health issues such as high blood pressure, heart disease, stroke, and excessive daytime sleepiness.

Diagnosing SDB usually begins with a sleep study (polysomnography), where data on your breathing, heart rate, oxygen levels, and brain activity are recorded while you sleep. This can be done in a sleep center or through a portable home sleep test. The results help identify the severity of your condition and determine the best treatment plan.

For many people, oral appliances—also known as dental sleep devices—are an effective treatment for mild to moderate obstructive sleep apnoea and snoring. These custom-fitted devices are designed by dentists to reposition the lower jaw or tongue, helping to keep the airway open during sleep. Common types of oral appliances include:

• Mandibular Advancement Devices (MADs): These reposition the lower jaw forward to prevent airway collapse.

• Tongue Retaining Devices (TRDs): These hold the tongue in a forward position to keep the airway clear.

• Custom Snore Guards: These are designed specifically to reduce snoring by preventing airway obstruction.

Oral appliances are a comfortable, non-invasive alternative to CPAP therapy, and many patients find them easier to tolerate. If you suspect sleep disordered breathing, consult a dentist trained in sleep medicine for a personalised treatment plan that can help improve your sleep and overall health.
