Airway Health: the missing link in dental treatment

When most people think about dentistry, they think about teeth—cavities, crowns, cleanings, and cosmetic improvements. But there is a foundational piece of health that often goes unnoticed: your AIRWAY.

Healthy breathing—especially during sleep—is essential not only for overall wellness, but also for long-term dental stability and comfort. Increasingly, dentistry is recognizing that airway health and oral health are deeply connected.

Why Airway Health Matters in Dentistry

Your airway is the pathway that allows oxygen to travel from your nose and mouth to your lungs. If that airway becomes partially blocked during sleep, your body may repeatedly struggle to breathe. These interruptions can significantly affect oxygen levels and sleep quality.

Poor airway function can contribute to:

A tooth crack due to grinding in a patient with untreated sleep disordered breathing.

• Teeth grinding and clenching (bruxism)

• Jaw pain and TMJ symptoms

• Worn or fractured teeth

• Gum inflammation

• Dry mouth

• Fatigue and daytime sleepiness

• Headaches

Often, the mouth shows signs of airway distress before a patient ever receives a sleep-related diagnosis.

The Role of Sleep and Obstructive Sleep Apnea

One of the most common airway disorders is Obstructive Sleep Apnea (OSA). OSA occurs when the airway collapses or becomes blocked during sleep, leading to repeated pauses in breathing. These pauses may last several seconds at a time and can happen dozens—or even hundreds—of times per night.

Because these events occur during sleep, it is common for patients to be unaware of their presence.

Using RDI to Assess Airway Risk

In our office, we use screening tools to help identify potential airway concerns. One important metric is the Respiratory Disturbance Index (RDI) - breathing disturbances per hour of sleep.

A high resolution pulse oximeter measures drops in blood oxygen which can estimate RDI.

A higher RDI may suggest an increased risk for obstructive sleep apnea or other sleep-disordered breathing patterns. While dentists in Massachusetts cannot diagnose sleep apnea—that diagnosis must be made by a licensed medical physician— estimating RDI allows us to:

• Screen for potential risk

• Identify patterns that may be impacting dental health

• Co-discover findings with patients

• Collaborate with medical providers when appropriate

Why This Matters for Your Dental Treatment

Airway health directly impacts the longevity of dental work. If a patient is grinding due to airway collapse, crowns and restorations may fracture prematurely. If sleep quality is compromised, inflammation and healing capacity can suffer.

By evaluating airway health alongside dental treatment, we aim to:

• Protect your investment in your dental care

• Improve long-term stability of restorations

• Support whole-body wellness

• Address root causes—not just symptoms

Dentistry is evolving. We now understand that the mouth is not separate from the rest of the body—it is part of a complex, interconnected system.

When we look at your airway, we are not just looking at sleep. We are looking at your energy, your inflammation levels, your jaw comfort, your dental stability, and your long-term health.

is appropriate for you. Your breathing matters. And healthy breathing supports a healthy smile.
