The role of the Dentist in Sleep Breathing Disorders
Why Your Dentist Might Be the First to Spot a Sleep Breathing Problem
When most people think about sleep disorders, they think of their GP or a hospital sleep clinic. What they rarely consider is that their dentist may be the first clinician to notice the signs — and in many cases, the best placed to help.
😴 What Is Obstructive Sleep Apnoea?
Obstructive sleep apnoea (OSA) is a condition in which the upper airway repeatedly collapses during sleep, causing oxygen levels to drop and sleep to fragment. It is associated with serious systemic consequences including hypertension, heart disease, stroke, and cognitive impairment. Despite affecting a significant proportion of the adult population, the vast majority of cases remain undiagnosed.
🦷 The Dentist as a Diagnostic Sentinel
Dentists examine the mouth, throat, and jaw at every routine appointment. During these visits, we are well positioned to identify clinical indicators that may suggest sleep-disordered breathing, including:
Tooth grinding (bruxism) — strongly associated with disrupted sleep
A narrow palate or recessed lower jaw — anatomical risk factors for airway collapse
Scalloped tongue margins or an enlarged tongue — potential signs of airway crowding
Daytime fatigue reported by patients during conversation
🌙 How Dentistry Can Help
Custom-fitted mandibular advancement devices (MADs) are an evidence-based, NICE-recognised treatment for mild to moderate OSA. These appliances reposition the lower jaw forward during sleep, reducing airway collapsibility and improving oxygen saturation. Research confirms that MADs demonstrate comparable effectiveness to CPAP therapy and are significantly better tolerated by patients over the long term.
🏥 A Multidisciplinary Approach
Dentistry does not replace medical sleep medicine — it complements it. At Whitland Dental Co, we work within a coordinated care pathway, using validated screening tools and, where indicated, referring for home sleep testing and specialist review.
If you snore, wake unrefreshed, or have been told you stop breathing in your sleep, your next dental appointment could be the most important health conversation you have this year.
