The Connection Between Sleep Apnoea and Oral Health: What Every Australian Should Know
Sleep apnoea is a common yet often under-recognised condition that can impact both general and oral health. At Hampstead Dental in Melbourne, we aim to raise awareness of how sleep apnoea may affect the mouth, teeth, and gums, and how dentists can support your overall care in collaboration with other health professionals.
What is Sleep Apnoea?
Sleep apnoea is a sleep-related breathing condition where breathing is interrupted during sleep. These episodes can last a few seconds or longer and may occur multiple times throughout the night. The most common form, obstructive sleep apnoea (OSA), occurs when the airway becomes partially or fully blocked during sleep due to the relaxation of throat muscles.
Possible Oral Health Impacts of Sleep Apnoea
Sleep apnoea may be associated with a range of oral signs and symptoms. Below are some of the oral health concerns that may be observed in individuals who have sleep apnoea:
Bruxism (Teeth Grinding)
Some individuals with sleep apnoea may clench or grind their teeth during sleep, which can contribute to tooth wear, sensitivity, and jaw discomfort.
Dry Mouth (Xerostomia)
Mouth breathing—sometimes linked to sleep apnoea—can contribute to dry mouth. A reduced flow of saliva may make the mouth feel dry and can increase the risk of plaque accumulation and tooth decay.
Gum Inflammation
Ongoing dry mouth and other contributing factors may be associated with gum inflammation or discomfort in some people.
Oral Appliances and Snoring Management
For individuals diagnosed with sleep apnoea by a qualified medical professional, oral appliances may be recommended as part of a treatment plan. These custom-fitted devices, typically worn during sleep, are designed to help maintain an open airway by adjusting the position of the jaw or tongue. If suitable, a dentist with appropriate training can provide and monitor these appliances.
It’s important to note that oral appliances are one of several treatment options, and their appropriateness depends on the severity of the condition and other individual factors, which must be assessed by a medical or dental practitioner.
The Role of Dentists in Identifying Concerns
During a dental check-up, your dentist may notice signs such as worn teeth, jaw discomfort, or dry mouth that could prompt further discussion about your sleep habits. While dentists do not diagnose sleep apnoea, they can work in collaboration with your general practitioner or sleep specialist to support your care.
If your dentist identifies signs that could be associated with sleep-related breathing issues, they may recommend you speak with a medical practitioner for further assessment, which could include a sleep study.
General Considerations for Managing Oral Health with Sleep Apnoea
Here are a few oral care tips that may help support your dental health:
-
Brush twice daily with fluoride toothpaste and floss once daily
-
Attend regular dental check-ups for personalised care and monitoring
-
Stay hydrated to reduce the sensation of dry mouth
-
Inform your dental practitioner if you use a CPAP machine or oral appliance
If you experience symptoms such as frequent snoring, daytime fatigue, or dry mouth, consider speaking with your GP. A medical assessment is essential to determine the presence of sleep apnoea and to explore appropriate treatment options.
