Sleep Apnea Is More Than Snoring! The Connection Between Your Airway and Dentistry

Can snoring be more than just a nighttime nuisance? Absolutely. While snoring may sometimes be harmless, it can also be a warning sign of obstructive sleep apnea (OSA), a sleep-related breathing disorder that deserves attention.

In this video, Dr. Sanghmitra Dasgupta explores the relationship between the airway, jaw position and dentistry—and explains why persistent snoring should not simply be ignored.

What Causes Snoring?

Your bedroom is not an airport! Yet, anyone who has slept beside a habitual snorer may recognise the sound of an aircraft engine taking off in the middle of the night.

Behind the humour lies an important physiological process.

During sleep, the muscles of the body relax, including those that help maintain the openness of the upper airway. If the airway becomes narrowed, airflow can cause surrounding soft tissues to vibrate, producing the familiar sound of snoring.

Several factors may contribute to this narrowing, including the anatomy of the upper airway, the position of the tongue and jaw, nasal obstruction, excess tissue around the neck and certain sleep-related factors.

Snoring, therefore, is not always simply a matter of sleeping noisily. It may indicate that airflow is encountering resistance.

When Does Snoring Become a Concern?

Occasional snoring does not necessarily mean that a person has sleep apnea. However, loud, habitual snoring—particularly when accompanied by other symptoms—warrants further evaluation.

Obstructive sleep apnea (OSA) occurs when the upper airway repeatedly becomes partially or completely blocked during sleep. These episodes can interrupt normal breathing, reduce oxygen levels and fragment sleep.

Possible warning signs include:

• Loud, habitual snoring

• Pauses in breathing noticed by a bed partner

• Gasping, choking or snorting during sleep

• Excessive daytime sleepiness or persistent fatigue

• Morning headaches

• Difficulty concentrating or unrefreshing sleep

Not everyone with OSA experiences all these symptoms. If sleep apnea is suspected, a medical evaluation and, when indicated, a sleep study are important. Snoring alone cannot confirm or exclude the diagnosis.

How Are the Jaw, Tongue and Airway Connected?

The upper airway is a dynamic structure. Its dimensions and stability are influenced by the surrounding soft tissues and craniofacial anatomy, including the position and relationship of the jaws.

During sleep, reduced muscle activity can make an already vulnerable airway more susceptible to narrowing or collapse. In some individuals, jaw position and the space available for the tongue may be relevant to this process.

This is where dentistry can contribute to the broader understanding and management of sleep-related breathing problems.

Dentists can recognise certain oral and craniofacial features that may warrant further assessment, ask relevant screening questions and collaborate with medical professionals when sleep-disordered breathing is suspected.

However, the relationship between the teeth, jaw, muscles and airway is complex. No single dental finding can diagnose sleep apnea, and improving the bite should not automatically be assumed to resolve a breathing disorder.

Where Does Neuromuscular Dentistry Fit In?

Neuromuscular dentistry considers the relationship between the teeth, jaw position and the muscles involved in mandibular function. This perspective encourages clinicians to assess the stomatognathic system as an interconnected functional unit rather than looking at the teeth in isolation.

In the video, Dr. Sanghmitra Dasgupta discusses the REU splint, described as a removable ideal occlusal splint, in the context of jaw position and occlusal harmony.

It is important to distinguish this approach from established treatment for obstructive sleep apnea. A splint intended primarily to optimise occlusion should not automatically be considered a treatment for OSA.

For appropriately selected patients with diagnosed OSA, a custom-made oral appliance designed to advance the mandible may be an option under the guidance of a qualified dental sleep-medicine practitioner and the patient's sleep physician. Such appliances are different in purpose and design from a conventional occlusal splint. Treatment selection and follow-up should be based on the patient's diagnosis, clinical needs and objective assessment of treatment effectiveness.

Neuromuscular assessment may form part of a broader clinical evaluation, but it should not replace medical diagnosis or evidence-based sleep-apnea management.

Why a Team Approach Matters

Sleep-disordered breathing often requires collaboration between healthcare professionals.

A sleep physician can evaluate symptoms and arrange appropriate diagnostic testing. A dentist trained in dental sleep medicine can assess suitability for an oral appliance when indicated. Other specialists may be involved depending on the patient's airway anatomy and associated conditions.

The goal is not merely to reduce the sound of snoring. It is to identify the underlying problem and provide appropriate care.

A quieter night does not, by itself, prove that sleep apnea has been adequately treated. Patients receiving treatment for OSA may require follow-up testing to confirm effectiveness.

Don't Ignore the Message Behind the Snore

Snoring may be amusing to describe, but persistent snoring accompanied by breathing pauses, gasping or daytime sleepiness deserves attention.

The airway, jaw and surrounding tissues are anatomically connected, and dentistry has a role in recognising relevant features and supporting coordinated care. The key is to use that role responsibly, with appropriate diagnosis, collaboration and follow-up.

As we explore in Beyond the Bite – The Harmony Principle, understanding oral function requires us to look beyond the teeth alone—while remaining grounded in sound clinical evidence.
