The Importance of Airway Dentistry: Enhancing Health Through Better Breathing

Airway Dentistry in Singapore

The air we breathe is essential for our bodies to function well. Airway dentistry focuses on how the structure of our mouth and jaws affects our ability to breathe properly. Airway dentists can spot issues with mouth and jaw development that might be associated with breathing or sleep problems. They understand the important link between oral health and overall health, recognising how airway problems can impact the whole body.

Proper breathing is vital, and not getting enough oxygen can harm your health and quality of life. By focusing on airway health, dentists can identify and treat the root causes of sleep and breathing issues, helping you feel better and live healthier.

The Role of Airway Dentists

Airway dentists play a crucial role in identifying and managing airway-related issues. Airway dentists check for sleep-related breathing problems by looking for signs of mouth breathing while you sleep. They examine things like tooth wear, tongue position, and the condition of the soft tissues in your mouth to identify potential issues. External signs include incomplete lip seal, dry mouth and lips, forward head posture, facial asymmetry, black eye rings and daytime sleepiness with poor focus.

Through routine dental exams, they can detect related signs of airway obstruction and collaborate with other healthcare providers to develop comprehensive treatment plans.

The Connection Between Airway Health and Dentistry

Here are some key ways in which airway health and dentistry are connected:

  • Breathing Patterns: Proper breathing ensures the body receives adequate oxygen. Mouth breathing can cause dental issues such as dry mouth, gum disease, and tooth decay. Incomplete lip seal will result in low tongue posture that can block the throat when breathing. The poor tongue muscles strength and wrong muscle memory will aggravate breathing during sleep, especially while lying down.

  • Sleep Disorders: Sleep apnoea, characterised by repeated interruptions in breathing during sleep, is often linked to airway obstructions. Sleep physicians can identify these issues and prescribe treatments, such as oral appliances, to keep the airway open. Our dentists are trained to measure the correct conditions for the mandibular advancement devices for sleep apnoea. Sometimes as a replacement for CPAP machine, particularly for those who are unable to tolerate the CPAP.

  • Teeth Alignment Correction: Misaligned teeth and jaw structures can obstruct the airway. Airway-focused teeth alignment treatment aims to correct these issues, ensuring the airway remains open.

  • Craniofacial Development: Proper development of the jaw and facial structures is crucial for maintaining a healthy airway. Early intervention in children can guide the growth of these structures, preventing future airway problems.

The Role of Tongue Posture

Tongue posture plays a critical role in maintaining an open airway and proper oral health. Correct tongue posture involves resting the tongue against the roof of the mouth, with the lips closed and teeth slightly apart.

Poor tongue posture can lead to various issues:

  • Mouth Breathing: Incorrect tongue posture often results in mouth breathing, which can cause dry mouth, gum disease, and an increased risk of cavities.
  • Sleep Apnoea: Poor tongue posture can contribute to the collapse of the airway during sleep, exacerbating conditions like sleep apnoea.
  • Teeth Alignment Problems: Incorrect tongue posture can affect the alignment of teeth and the development of the jaw, leading to malocclusion and other teeth alignment issues.

Symptoms Indicating Airway Issues

Recognising the symptoms of airway problems is crucial for early intervention and effective treatment. If you or a loved one experiences any of the following signs, it may indicate an airway issue that needs attention:

  • Chronic snoring
  • Mouth breathing, especially during sleep
  • Frequent waking at night or insomnia
  • Daytime fatigue or drowsiness
  • Difficulty concentrating or hyperactivity in children
  • Grinding of teeth (bruxism)
  • Chronic headaches or migraines

Diagnostic Tools in Airway Dentistry

Airway dentistry uses various diagnostic tools to assess and monitor airway health:

  1. History taking – A detailed history helps to formulate a complete picture of the health position of an individual. Any deviation from the norm can be presented as daily challenges such as swallowing problems, forward head posture, ringing in ears, dizziness, headaches, neck stiffness and the list goes on. This is an important step to establish the short and long term plans as part of overall management.
  2. Sleep Studies: Hospital and home sleep tests can diagnose sleep apnoea and other sleep-related disorders. 
  3. Epworth Sleepiness Scale: A questionnaire assessing daytime sleepiness, aiding in the identification of potential sleep disorders.

Treatment Options for Airway Issues in Dentistry

1. Oral Appliances: Custom-made devices reposition the jaw and tongue to keep the airway open during sleep, commonly used to treat mild to moderate sleep apnoea.

2. Myofunctional Therapy: Exercises that strengthen the muscles of the mouth and throat, improving tongue posture, breathing patterns, and airway function.

3. Teeth Alignment Treatments: At DP Dental, we use clear aligners to correct misaligned teeth and jaw structures (such as deep bite), as part of the management in achieving better craniofacial support for airway.

DP Dental’s Commitment to Airway Dentistry

DP Dental adopts a functional and integrative approach to dentistry, emphasising the overall health and wellness of patients by addressing the root causes of oral disease. Habits like mouth breathing may be hard to break, but through simple, guided exercises, we can train you and your child to create new, healthy habits for overall wellness. Through myofunctional therapy, we can retrain and strengthen the orofacial muscles so they work together in harmony.

Dr Yue Weng Cheu (Founder & Group Clinical Director, DP Dental) has extensive training, including the full TMD continuum at Occlusion Connections in the USA and he did two mini-residencies on Dental Sleep Medicine with TUFTS University School of Medicine 2018 and 2020). He collaborates with other health practitioners to improve tongue, breathing, and sleep functions, facilitating comprehensive recovery for patients.

Dr Yue is also the founder of the School of Linguadontics, an education platform that explores the connections between tongue, airway, and sleep, and their impact on overall health. The term “Linguadontics,” coined by Dr Yue, highlights the importance of tongue function and posture in maintaining both oral and overall health.

Frequently Asked Questions

What is airway dentistry?
Airway dentistry looks at how the structure of the mouth and jaws affects your ability to breathe. A dentist trained in it checks for signs of breathing difficulty during sleep, such as tooth wear, low tongue position and the condition of the soft tissues in the mouth, and works alongside other healthcare providers where a wider assessment is needed.
What are the signs of an airway problem?
Common signs include chronic snoring, mouth breathing during sleep, frequent waking at night, daytime fatigue, difficulty concentrating or hyperactivity in children, teeth grinding, and chronic headaches. A dentist may also notice external signs such as an incomplete lip seal, dry mouth and lips, forward head posture, facial asymmetry and dark rings under the eyes.
What is correct tongue posture, and why does it matter?
Correct tongue posture means the tongue rests against the roof of the mouth, with the lips closed and the teeth slightly apart. When the tongue sits low instead, it is associated with mouth breathing, a greater tendency for the airway to narrow during sleep, and changes in how the teeth align and the jaw develops.
Can a dentist help with sleep apnoea?
A dentist trained in dental sleep medicine can fit a custom oral appliance that repositions the jaw and tongue to help hold the airway open during sleep. These are commonly used for mild to moderate sleep apnoea, and sometimes for people who cannot tolerate a CPAP machine. Diagnosis itself comes from a sleep study, interpreted by a physician.
How is an airway problem assessed?
Assessment usually begins with a detailed history covering issues such as swallowing difficulty, forward head posture, headaches, ringing in the ears and neck stiffness. It may then include a hospital or home sleep study to test for sleep apnoea, and a questionnaire such as the Epworth Sleepiness Scale to gauge daytime sleepiness.
What treatments are used for airway issues?
Three approaches are common: custom oral appliances that reposition the jaw and tongue during sleep; myofunctional therapy, a set of exercises that strengthen the muscles of the mouth and throat to improve tongue posture and breathing patterns; and teeth alignment treatment using clear aligners where misaligned teeth or jaw structures reduce the space available for the airway.
