What is Sleep Apnoea?
Obstructive sleep apnoea (OSA) is a condition in which the airway partially or completely collapses during sleep, causing repeated pauses in breathing. These pauses can last from a few seconds to over a minute and may occur many times throughout the night, disrupting sleep quality and reducing oxygen levels.
Snoring is often associated with sleep apnoea, though not everyone who snores has the condition. Loud, habitual snoring — particularly when accompanied by gasping, choking sounds or excessive daytime tiredness — may be a sign of OSA and warrants further investigation.
Signs Your Dentist May Notice
Dentists are often among the first health professionals to notice potential signs of sleep apnoea during routine examinations. Dental signs that may suggest a sleep-disordered breathing issue include:
- Teeth grinding (bruxism) — wear patterns on the teeth consistent with nighttime clenching or grinding, which is commonly associated with sleep apnoea
- Scalloped tongue — indentations along the edges of the tongue caused by pressing against the teeth during sleep
- Small or recessed jaw — jaw structure can contribute to airway narrowing during sleep
- Redness or inflammation of the throat — visible irritation at the back of the throat from snoring or mouth breathing
- Dry mouth — waking with a dry mouth can indicate mouth breathing during sleep
- Cracked, chipped or fractured teeth — from the forces generated by sleep bruxism
Common Symptoms of Sleep Apnoea
In addition to dental signs, general symptoms that may indicate sleep apnoea include:
- Loud, persistent snoring
- Witnessed pauses in breathing during sleep
- Waking with a choking or gasping sensation
- Excessive daytime sleepiness and fatigue
- Morning headaches
- Difficulty concentrating or memory problems
- Irritability or mood changes
How Dentistry Can Help
While sleep apnoea is diagnosed through a sleep study arranged by a doctor or sleep physician, dental professionals can play an important role in its management. For mild to moderate obstructive sleep apnoea, or for patients who cannot tolerate CPAP therapy, a mandibular advancement device (MAD) may be an option.
- Mandibular advancement devices — custom-fitted oral appliances worn during sleep that gently hold the lower jaw in a forward position, helping to keep the airway open
- Custom fit — devices are made from dental impressions to fit comfortably and precisely, improving compliance compared to over-the-counter alternatives
- Ongoing monitoring — regular review appointments to assess fit, comfort and the condition of the appliance
