# Airway Orthodontics: What’s Behind It?

Airway Orthodontics is an airway-focused approach within orthodontics that incorporates not only tooth alignment but also the function of the upper airway, the development of the craniofacial structures, and the function of the tongue and lips into diagnostics and treatment planning. It is a treatment approach that goes beyond simple tooth correction and places the significance of the airway for health, sleep quality, and jaw development at the center.
The term originates from the English-speaking world and is increasingly being used in German-language professional discourse as well. This article explains what Airway Orthodontics is, situates the concept scientifically, and shows in which situations an airway-focused perspective on orthodontic findings may be meaningful.
What Is Airway Orthodontics?
Airway Orthodontics describes an expanded orthodontic treatment approach in which the form and function of the upper airway are incorporated as an additional evaluation criterion in diagnostics and therapy planning. Orthodontics and airway are closely interconnected, as the development of jaw structure has a direct influence on airway function. The focus is on the observation that the development of the upper jaw, the position of the lower jaw, tongue posture, and breathing patterns are functionally interrelated.
Traditional orthodontics concentrates on the correction of misaligned teeth and jaws with a focus on occlusion and esthetics. The airway-focused approach expands this perspective to include questions such as: Is breathing through the nose or through the mouth? Does the tongue rest against the palate at rest? Is the upper jaw sufficiently wide for a physiological tongue position? Are there signs of narrowing of the upper airway?
In contrast to purely tooth-oriented methods, which often do not systematically consider anatomical and functional causes, Airway Orthodontics is typically part of an interdisciplinary approach. Especially in children, the professional literature discusses early orthodontic and functional examination to identify developmental disorders in a timely manner. The goal is to address not only symptoms but also possible causes such as soft tissue dysfunction or an unfavorable resting tongue position.
Important to note: Airway Orthodontics is not a separate specialty and not an officially certified specialization. It is an expanded diagnostic and therapeutic perspective within orthodontics that is discussed in the international professional literature on airway treatment.

The Scientific Foundation
The relationship between craniofacial development, jaw growth, and the airways has been documented in the medical literature for decades. The interactions between airway function, breathing patterns, and jaw development are considered multifactorial and not a simple cause-and-effect relationship.
Several studies document that orthodontic expansion of the upper jaw (palatal expansion, also called rapid palatal expansion or RPE) can measurably improve nasal airway volume and nasal airflow. Patients also frequently report subjective improvement in breathing comfort, although the extent varies greatly between individuals and cannot be reliably predicted.
In children with craniofacial anomalies and obstructive sleep apnea (OSA), orthodontic interventions are discussed in the professional literature as a causal treatment option (airway treatment) — however, explicitly within the framework of interdisciplinary care involving sleep medicine and otolaryngology. The evidence base for effectiveness is heterogeneous; further research is considered necessary to formulate clear treatment recommendations.
The Three Pillars of the Airway-Focused Approach
Airways and Nasal Breathing
The airway refers to the breathing passage through which air reaches the lungs — a central element for health, sleep quality, and the development of the jaw and face. Free nasal breathing is considered the physiological standard. Chronic mouth breathing can be an indication of anatomical or functional constrictions in the nose, throat, or palate. Possible causes include enlarged pharyngeal or palatine tonsils, a narrow upper jaw, a deviated nasal septum, or a low tongue resting position. A narrow upper jaw is frequently associated with a constricted nasal cavity, which can further compromise the airway. Identifying these causes is typically done interdisciplinarily and not solely through orthodontics.
Jaw and Facial Development
The shape and size of the upper and lower jaws influence the available space for teeth and tongue and thus also affect the airways. Healthy jaw development can have a positive impact on airway efficiency, facial shape, and long-term dental health; when the upper jaw is too narrow, palatal expansion can help widen the jaw space. A narrow or underdeveloped upper jaw can promote an unfavorable tongue position and subsequently be associated with airway issues. In growing patients, these structures can be influenced orthodontically, for example through procedures such as palatal expansion. In adults, the skeletal options are more limited, as facial growth is complete.
Function of the Tongue and Musculature
The tongue, lips, and facial muscles shape the dental arch and influence airway function throughout life. The position of the tongue plays a central role in correct swallowing, maintaining open airways, and jaw development. A low tongue resting posture, open lip seal, or atypical swallowing pattern are considered in orofacial myofunctional evaluation. Soft tissue dysfunction can contribute to the development of misalignment and is specifically addressed as part of orthodontic care. Myofunctional therapy is often used alongside orthodontic treatment — however, the evidence for its isolated effectiveness is assessed differently.
For whom can an airway-focused perspective be relevant?
In Children
In children, the following observations are described in the literature as reasons for an airway assessment: persistent mouth breathing, regular snoring, restless sleep, frequent respiratory infections, pronounced dark circles under the eyes, or an open lip seal at rest. These signs are nonspecific and can have many causes. They do not replace medical diagnosis, but can be an indication for an orthodontic and, if necessary, interdisciplinary examination .
Particularly in cases of diagnosed obstructive sleep apnea in childhood, ENT findings (such as adenoids and tonsils) should first be evaluated before orthodontic airway treatment is considered.
In Adults
In adults, airway concerns are discussed primarily in connection with medically diagnosed obstructive sleep apnea, snoring, or temporomandibular disorder (TMD); in cases of diagnosed sleep apnea, a mandibular advancement device can be a gentle treatment option. Orthodontically fabricated mandibular advancement devices are an established treatment option for mild to moderate obstructive sleep apnea and are included in relevant guidelines. Detailed information on this treatment approach can be found on the page about snoring and sleep apnea. Skeletal changes are limited in adults. Treatment therefore focuses more often on functional and appliance-based solutions as well as interdisciplinary coordination with sleep medicine and ENT.

Diagnostic Components
An airway evaluation in the orthodontic context can include the following elements:
The clinical examination assesses not only tooth alignment and bite alignment but also lip rest position, tongue position, lip closure, and breathing pattern. The imaging diagnostics may be supplemented, depending on the indication, by three-dimensional methods such as a CBCT (cone beam computed tomography), which enables assessment of bone structures and airway space. An airway analysis can quantify the spatial relationships in the nasal and pharyngeal area. If sleep disordered breathing is suspected, a referral to sleep medicine for polysomnography is made. The orofacial myofunctional assessment documents tongue, swallowing, and breathing function.
Which of these components make sense in a given case depends on the individual findings and should be determined by a specialist in orthodontics (orthodontist) who can assess not only tooth position but also the airways and the structural health of the jaw.
Treatment Options in the Airway-Oriented Context
The following procedures are discussed in the literature in connection with Airway Orthodontics. They are not specific "airway procedures" but established orthodontic and interdisciplinary treatment pathways that are applied depending on the findings. The decision on the use of each therapeutic method ultimately always rests with the orthodontist.
Rapid maxillary expansion (RME) is among the best-studied procedures. It widens the upper jaw and can positively influence nasal volume. Functional orthodontic appliances can be used in growing patients to guide jaw growth. Fixed or removable appliances — including aligners and fixed brackets (braces) — are used to correct tooth alignment and bite alignment; detailed information on fixed braces for correcting misalignment shows how such appliances can be used in various treatment contexts; in airway-oriented approaches, the emphasis is additionally on supporting breathing and jaw development. Mandibular advancement devices are used in adults with mild to moderate sleep apnea as an evidence-based treatment option (airway treatment); if there are accompanying symptoms in the temporomandibular joint, treatment options for jaw popping may also become relevant. Myofunctional therapy complements treatment through exercises to improve tongue posture, lip closure, and swallowing pattern and can be embedded in a comprehensive, function-oriented therapeutic concept.
An early orthodontic examination can help identify airway-related findings and support the development of the face and jaw. Which measure is appropriate in an individual case—and whether there is an orthodontic indication at all—can only be determined through an individual assessment.
Connection to Mouth Breathing
The consequences of chronic mouth breathing are a central point of intersection between traditional and airway-focused orthodontics. Understanding the relationship between airways, breathing, and orthodontics makes it clear that these areas are closely connected to sleep quality and overall health. Mouth breathing can be both a cause and a consequence of structural or functional abnormalities. An isolated orthodontic treatment without clarifying the breathing cause often falls short in many cases. Conversely, ENT treatment alone—such as for adenoids—without considering jaw development can also remain incomplete; it is often sensible to embed this within a comprehensive concept, as can be offered by a specialized orthodontic practice with an interdisciplinary approach.
Precisely this intersection perspective is the core contribution of an airway-focused view: recognizing when an orthodontic assessment should be part of a larger, interdisciplinary picture.
Why Airway Orthodontics Goes Beyond Tooth Alignment
Airway Orthodontics does not describe a new treatment method, but rather an expanded perspective within orthodontics. At the center is the understanding that teeth and jaw growth, airway function, breathing patterns, and muscle function are interconnected. Individual procedures such as palatal expansion and mandibular advancement devices are particularly well-supported scientifically. The effectiveness of a comprehensive airway treatment concept is the subject of ongoing research and should be communicated with appropriate professional restraint.
For patients, this means above all one thing: Anyone who observes signs such as chronic mouth breathing, abnormal breathing patterns, or indications of sleep disordered breathing is well-advised to address these topics during the orthodontic assessment—ideally in collaboration with their primary care physicians, ENT specialists, and, if necessary, sleep medicine specialists.

Frequently Asked Questions

Is Airway Orthodontics scientifically recognized?
The term "Airway Orthodontics" is not an official professional designation. However, the underlying connections between jaw growth, airways, and breathing are documented in the medical literature. Individual procedures — particularly palatal expansion and mandibular advancement devices — are well researched scientifically. The effectiveness of a comprehensive airway treatment concept is not uniformly assessed and remains a subject of ongoing research.
At what age does an airway-focused orthodontic examination make sense?
In the international literature, an initial airway evaluation is often recommended as early as around age seven, since growth patterns can be actively influenced during this phase. When clear signs such as persistent mouth breathing, regular snoring, or restless sleep are present, an earlier consultation may also be advisable.
Does health insurance cover the costs?
Cost coverage is determined by the respective orthodontic indication groups (KIG) of statutory health insurance. Procedures such as palatal expansion are typically covered when medically indicated. For private dental services or specific diagnostic procedures — such as CBCT imaging — out-of-pocket costs may apply. A binding statement is provided after individual examination and treatment plan.
Do I need an ENT specialist or sleep medicine physician as well?
In many cases, yes. Particularly when sleep apnea is suspected, sleep medicine diagnostics by an appropriately qualified physician is essential. ENT findings are important to rule out or treat anatomical restrictions or enlarged tonsils. An airway-focused orthodontic treatment does not replace medical diagnostics — it is one component within an interdisciplinary care network.
How does Airway Orthodontics differ from "regular" orthodontic treatment?
The difference lies not primarily in the methods, but in the diagnostic perspective. Function, breathing, and interactions with adjacent medical fields receive greater weight in examination and treatment planning. Carefully conducted traditional orthodontics already considers these aspects — the airway focused term simply makes them more explicit.
Where does the term Airway Orthodontics come from?
The term originates from English-language professional discourse, primarily in the United States. Various practices, professional societies, and continuing education providers have popularized it in recent years. In German-speaking countries, the term is increasingly gaining traction, though it has not yet been incorporated into official clinical guidelines.
