Adult care

Your jaw pain, broken sleep, and exhausted mornings may not be just stress.

We assess the airway and structural factors that can lie behind adult symptoms, and aim to address them rather than manage them indefinitely.

The bigger picture

Most adults who arrive at Growth and Airway have already spent years collecting diagnoses.

A mouthguard from one dentist. A CPAP machine from a sleep clinic. Painkillers for the headaches. Each intervention addresses a symptom in isolation, yet the underlying picture remains unresolved.

Often the reason is developmental. The jaws, palate, and airway form during childhood, shaped by breathing patterns, tongue posture, muscle function, and diet. When any of these factors are compromised early in life, the facial skeleton can develop in a way that leaves the airway narrower than it should be, the jaw positioned further back than is functional, and the bite under chronic strain.

The body adapts. For years, sometimes decades, it compensates. Then, in adulthood, those compensations begin to break down. TMJ pain emerges. Sleep quality deteriorates. Clenching becomes habitual. Headaches become weekly. None of this happens suddenly. It is the accumulated result of a structure that has been working against its own limitations for a very long time.

What we treat in adults

01

TMJ and jaw pain

The temporomandibular joint connects the lower jaw to the skull. When the jaw sits in a position that is structurally compromised, whether due to a narrow palate, a retruded lower jaw, or bite imbalance, that joint can be placed under load it was not designed to carry.

The symptoms that follow can include clicking or popping on opening, a jaw that locks or catches, facial pain around the cheeks and temples, chronic headaches, and ear pain or fullness. These are not random occurrences. They can be traced back to how the jaw is positioned and how the surrounding structures function.

Treatment at Growth and Airway focuses on understanding that position. Where is the jaw sitting? What is driving the strain? Functional appliances, bite adjustment, and soft tissue work can all form part of an approach that addresses the mechanics rather than simply managing the discomfort.

Sleep and breathing

Adult sleep apnoea occurs when the airway collapses or narrows repeatedly during sleep, disrupting breathing and pulling the body out of restorative sleep cycles. Snoring, waking unrefreshed, daytime fatigue, and morning headaches are among the most common signs.

CPAP therapy can be effective at keeping the airway open mechanically, but it does not alter the underlying structure that made the airway vulnerable in the first place. Dental and structural treatment takes a different approach. By working with the dimensions of the jaw and palate, it can address some of the contributing anatomical factors rather than relying solely on pressure support during sleep.

Mouth breathing, whether during the day or at night, compounds these difficulties. Breathing through the nose filters, warms, and humidifies air; it also engages the diaphragm correctly and supports healthy oxygen exchange. When mouth breathing becomes habitual in adulthood, it can sustain the very postural and structural patterns that worsen sleep and airway function.

Bruxism

Teeth grinding and clenching are commonly attributed to stress, and while stress can be a contributing factor, it rarely tells the whole story. Bruxism can also be the body's response to an airway that is compromised during sleep. When the airway narrows, the jaw can move forward instinctively in an attempt to open the throat. That movement, repeated night after night, manifests as clenching or grinding.

Treating bruxism with a night guard alone can protect the teeth without resolving the reason the grinding is happening. Understanding the structural and breathing context can be as relevant as the grinding itself.

Adult orthodontics

Orthodontic treatment in adults at Growth and Airway is not positioned around aesthetics. It is concerned with function: how the jaws relate to one another, how much space the tongue has, and whether the airway has the dimensions it needs.

Appliances such as the ALF (Advanced Light Force) and functional expansion devices work gradually, using light, biologically respectful forces to encourage change in jaw position and palate width. This can be relevant for adults who present with a narrow upper arch, a retruded lower jaw, or a history of extractions that reduced available space. These approaches are not a quick fix. They are a considered, measured process.

What to expect

A thorough assessment before any conclusions

An initial consultation is about understanding what may be behind your symptoms, in plain terms.

01

Clinical assessment

A thorough clinical assessment, including an evaluation of the bite, jaw position, and TMJ function, along with an airway assessment and a review of breathing and sleep patterns.

02

Imaging where appropriate

Where appropriate, a cone beam CT scan can be used to measure airway dimensions and identify any structural factors that may not be visible on a standard examination. Tongue function and soft tissue health are also assessed.

03

A clear picture

From that assessment, a picture of the contributing factors can be built. Treatment is then discussed in plain terms, with options explained and a realistic sense of what each stage involves.

Common questions

Questions adults often ask

A few of the ones we hear most. The full list answers more across every topic.

Can jaw problems cause headaches?

Yes, they can. The jaw, neck, and head share muscle groups and structural relationships. Where jaw alignment is compromised, the muscles around the TMJ, temples, and neck can carry excess tension, which can contribute to headaches. Oral infections stemming from root canals or extraction sites can also cause inflammation in the jaw, ear, and surrounding tissues.

Is it too late to seek treatment as an adult?

No. Adults can achieve meaningful functional improvements through orthodontic expansion, myofunctional therapy, and TMJ-focused care. Adult treatment tends to involve more layers of accumulated dysfunction compared to childhood cases, but that does not make it without value. The goal is functional restoration: better breathing, reduced jaw pain, and improved sleep, not cosmetic change.

I have been told I grind my teeth. What does that mean for me?

Bruxism, the clenching and grinding of teeth, is frequently linked to airway restriction and disrupted sleep. Where the airway is compromised, the jaw can be pushed back and the muscles around it can overwork during sleep. Addressing the underlying structural and breathing factors, rather than simply fitting a night guard, can be a more complete approach.

Can poor jaw development affect posture?

It can. Mouth breathing and compromised airways lead to different muscle recruitment patterns compared to nasal breathing. Over time, those patterns influence how the bones of the head, neck, and back develop and how the body holds itself. Forward head posture is a common presentation in patients with long-standing airway and jaw dysfunction.

I have had a lot of dental work over the years. Does that affect my suitability for treatment?

A detailed history of previous dental work is part of our assessment. We also evaluate for dental infections, including at old root canal and extraction sites, which can be symptom-free in the mouth but may contribute to systemic inflammation and joint pain. All of this is considered when planning care.
