Start with the mouth.
Start with the mouth.
See how it connects to your whole health.
The structure and function of the mouth shape how we chew and swallow every day, and they are closely tied to breathing and sleep.
Lumairui brings together oral assessment, myofunctional training, nutrition and lifestyle care, walking with children and adults toward easier breathing, more settled sleep and better days.
Concerns
Concerns show up in different places. The mouth may be a missing piece worth looking at.
Snoring, mouth breathing, still tired after sleep.
Teeth grinding, a tight jaw, discomfort when chewing.
Crowded teeth, or teeth moving again after orthodontics.
Headaches or neck and shoulder discomfort, together with poor sleep.
A long-term health condition, along with snoring or night-time breathing concerns.
A child who sleeps restlessly, or whose daytime energy, focus or growth is a worry.
These situations can have different causes. Looking at oral structure, function and sleep together helps show whether there are factors that need to be cared for jointly.
Mouth and body
The mouth's influence may reach further than you feel.
The jaws and dental arches form the space inside the mouth. The tongue and surrounding muscles take part in swallowing, chewing and breathing. When structure or function is limited, it may be worth assessing breathing, sleep and overall health alongside it.
Structure and space
How the upper and lower jaws, dental arches, tongue and upper airway sit in relation to each other. "How teeth line up" and "oral space and function" are different things to assess.
Function and use
Nasal breathing, how the lips rest, tongue position, swallowing and chewing. Structure and function need to be looked at together, and other factors such as nasal blockage checked too.
Sleep and whole-body health
Sleep-disordered breathing can affect how continuous sleep is and how alert you feel by day, and is associated with some cardiovascular and metabolic conditions.
"Sleep-related breathing problems are associated with whole-body conditions" does not mean "these conditions are all caused by an underdeveloped jaw".
For example, the American Heart Association recommends screening some patients with hard-to-control blood pressure or recurrent atrial fibrillation for obstructive sleep apnoea (OSA). That supports assessment across specialties; it does not show that an oral appliance treats heart disease. AHA scientific statement, 2021
When different concerns appear together, it is worth seeing how they relate.
Who it's for
Adults and children are assessed in different ways.
Adults and whole-body health
The problems that keep coming back deserve a fuller look.
You may already have sought help for sleep, headaches, jaw discomfort or long-term tiredness. If these come with snoring, mouth breathing, grinding or changes in how your mouth works, you can talk with your own doctor about adding an oral and sleep-breathing assessment.
- Breathing and nose: long-term congestion, habitual mouth breathing
- Sleep and daytime tiredness: snoring, waking up gasping, still tired after a long sleep, difficulty using CPAP
- Headaches, focus and mood: morning headaches, reduced concentration, brain fog
- Jaw and recurring dental concerns: grinding, clenching, jaw-joint discomfort
- Orthodontics and facial structure: crowded teeth, a second round of orthodontics
- Neck, shoulders, posture and recurring pain, and sleep-breathing signs alongside heart or metabolic health
We do not promise that oral care will improve an existing condition; those conditions stay with the specialists who manage them.
Children's growth and breathing
Is your child sleeping well? Small signs during growth are worth understanding early.
Always sleeping with their mouth open, often snoring, hard to wake in the morning; easily distracted or up and down during the day, or finding meals hard work. These everyday worries are worth understanding through sleep, breathing and oral function together.
- "They sleep for ages, so why is getting up so hard?"
- "They can't sit still and lose focus in the day. Could that be about sleep too?"
- "Their teeth are getting more crowded, and their mouth never seems to close."
- "Why are eating, chewing and swallowing always such a struggle?"
We look together at: jaw, face and dental arch development; nose, tonsil and adenoid history; tongue and lip function; sleep and breathing observations; and habits the family can realistically change.
None of these signs alone is a basis for diagnosis, and attention or mood difficulties should not be put down to the mouth. Whether to use an appliance, and when to start, depends on each child. NHLBI: sleep apnoea in children
Our care
From structure to habits, care that fits into daily life.
Custom oral appliance
Oral myofunctional training
Diet and lifestyle adjustments
Whole-body health assessment
Planned around each person's needs, with app records and a dedicated care coordinator to keep tracking, discussing and adjusting. Not everyone needs the same combination.
Integrated care pathway
- Getting to know youYour concerns, existing diagnoses and the everyday goals you want to work toward.
- Professional assessmentAs needed: oral structure, teeth and gums, muscle function, breathing and sleep, and overall health.
- Planning togetherThe options, expected goals, limits, risks, costs and what you will need to do.
- Personalised careMay include a custom oral appliance, myofunctional training, and diet and lifestyle adjustments.
- Follow-up and adjustmentReturn visits, any needed tests, app records and your care coordinator, to review progress and difficulties.
Keeping up with care helps it work in practice, but how much things change depends on many factors. If progress stalls, we reassess together.
Epigenetics and lifestyle
If DNA is an instruction manual, epigenetic regulation is like the markings that affect how a cell reads it. It does not change the order of the letters in DNA; it helps regulate how genes are expressed. Development, environment and some lifestyle factors, such as diet and smoking, can influence these processes. NHGRI: Epigenomics fact sheet
That is why, alongside any oral appliance that is needed, care also covers diet, sleep, muscle function and habits, so you know how you can take part day to day. Epigenetics offers a way to understand biological regulation; the concept alone does not prove that any particular programme can make the jaw grow again at any age.
Evidence
From clinical experience to published research, the basis made clear.
The studies below help explain why assessment across specialties is worthwhile. Each one notes what it can and cannot show. Consented, de-identified clinical cases will be published here once they are ready.
Myofunctional training
- What it studied
- 31 people; some measures improved.
- What it cannot show
- A small, short study; it does not show long-term results.
Myofunctional therapy overall
- What it studied
- 9 trials, 347 people; some results were favourable.
- What it cannot show
- Certainty of evidence and long-term data remain limited.
Persistent OSA in children
- What it studied
- For children with certain craniofacial features and OSA that persists after adenotonsillectomy, orthodontic and dentofacial orthopaedic treatment may be considered.
- What it cannot show
- A conditional recommendation, with very low certainty of evidence.
Heart health and sleep breathing
- What it studied
- Supports OSA screening for certain cardiovascular patients.
- What it cannot show
- That an oral appliance treats cardiovascular disease.

FAQ
What you may want to know before you start.
Is this right for me?
My teeth are straight. Is this still worth looking into?
How teeth look is only one part. If you have ongoing sleep-breathing or oral function concerns, you can discuss whether an assessment makes sense.
From what age can a child start?
Assessment is adapted to age, development and symptoms. When to start, and whether an appliance is needed, is decided by professional assessment.
Can adults still see change?
Adults can still be assessed for function and structure, but how much can change depends on the jaw, gums and overall health.
About the care
Do I have to wear an appliance?
Not necessarily. The combination of care depends on the assessment.
Does it hurt? Is surgery or medication involved?
We focus on non-surgical, non-drug options suited to each person, and on comfort. Appliances can still cause discomfort or changes to the bite, and other conditions may need different treatment.
Does functional medicine always mean lots of tests and supplements?
It should not be assumed. Any test or supplement needs an individual reason, and an explanation of how it changes your care.
Existing conditions and treatment
Will this solve my high blood pressure, anxiety, headaches or gut problems?
These can have many causes. Assessment aims to find whether there are oral or sleep factors that need joint care; it cannot guarantee that oral care will treat an existing condition.
Can I stop using CPAP or my current medication?
Do not stop on your own. Any change should be decided by your own doctor based on follow-up results.
Does poor attention mean my child has a mouth problem?
No, that cannot be concluded. If it comes with snoring, mouth breathing or restless sleep, it is worth adding a sleep assessment while continuing existing developmental or specialist care.
Time, cost and commitment
How long does it take, and what does it cost?
After assessment we explain the likely stages, how the cost is made up and any possible later adjustments.
What if I've worked hard and nothing has improved?
The diagnosis, goals and plan should be reviewed again. Limited progress should never be put down simply to the patient not trying hard enough.
