The claim the internet got too excited about
Myofunctional therapy has had a strange journey online. In one corner it is dismissed as fringe; in the other it is sold as a way to rebuild your face, fix sleep apnoea, and replace braces. Both extremes are wrong, and the truth sits in a more useful middle.
Here is the honest version. Myofunctional therapy is a real, structured discipline — orofacial myofunctional therapy, to give it its full name — with a genuine evidence base in specific areas. It retrains the muscles of the mouth and face to do their jobs properly: where the tongue rests, how you swallow, whether your lips seal, whether you breathe through your nose. In the right cases those things matter, and correcting them can help. What it cannot do is reshape an adult's bones or guarantee a transformation. We treat it as what it is — a valuable adjunct that may support good outcomes, used alongside proper dental and, where needed, medical assessment.
We approach orthodontics with a long-term smile view and an airway-aware lens, so this discipline sits naturally beside the whole-health dentistry we already practise. Below is what it actually involves, what the evidence supports, and where we are careful not to overclaim.
What myofunctional therapy actually is
At its core, myofunctional therapy treats four resting and functional habits that many people get subtly wrong.
Tongue posture. The tongue is designed to rest gently against the roof of the mouth, not to sit low against the lower teeth. Low tongue posture is associated with a range of developmental and functional patterns. Where tongue-tie may be a factor, our guide to adult tongue tie covers symptoms and assessment.
Nasal breathing. The nose is the body's intended airway at rest. Habitual mouth breathing changes how the face and jaw are used and is a frequent target of therapy.
Lip seal. Lips resting together, rather than parted, supports nasal breathing and balanced muscle activity around the mouth.
Swallowing pattern. Many people swallow with a "tongue thrust" — pushing the tongue forward against or between the teeth — which can work against orthodontic results over time.
The therapy itself is a course of specific, repeated exercises, usually over several months, taught and progressed by a trained therapist. It is closer to physiotherapy for the mouth than to anything passive. The work is the patient's; the role of the clinician is to assess, prescribe correctly, and progress sensibly.
What the evidence may support — stated carefully
This is where honesty matters most, so we will be precise about the language. The strongest, most defensible claim is that myofunctional therapy may support outcomes in defined areas, used as an adjunct rather than a stand-alone treatment.
It may support orthodontic stability. Correcting a tongue thrust or low tongue posture can reduce the forces that push teeth back out of position, which may help results hold — part of why we think about retention after treatment and relapse from the start, designing with your future in mind rather than for the day the braces come off.
It may support breathing and resting patterns. Retraining nasal breathing and lip seal can help patients who have habitually breathed through the mouth, with knock-on benefits some people notice in daytime comfort.
It may form part of a wider airway plan. In children especially, and as an adjunct in adults, it is increasingly used alongside other airway-aware care. In sleep-related breathing problems it is studied as a contributing element of management, not a treatment in its own right — and any breathing concern of that kind belongs with sleep-medicine specialists, with whom we work alongside rather than in place of.
What we will not say is that it cures conditions, replaces orthodontics, or remodels the adult facial skeleton. The exercises change muscle function and habit; they do not change adult bone. Keeping that line clear is the difference between a clinic you can trust and one selling a fantasy.
Where it fits in airway-aware orthodontics
The reason myofunctional therapy interests us is that it speaks to something we already believe about teeth: function and form are linked, and a good result has to hold for the long term.
We favour arch expansion where possible and a non-extraction method when the biomechanics allow — seeing how your teeth may support or improve your smile rather than simply straightening and moving on. Muscle function sits underneath all of that. If the tongue rests low and pushes forward on every swallow, it works against the very result an aligner is trying to create. Addressing the muscle pattern, where it is genuinely a factor, supports the orthodontic work and the long-term smile view that guides how we plan. This is restorative thinking applied to orthodontics — optimal function and long-term functional outcomes, not a result designed only for the photo.
For the right patient, that means myofunctional exercises run alongside orthodontic teeth straightening, not instead of it. For another patient, the muscle pattern is not the issue and the exercises would add effort without benefit — and we will say so. Proportionate care means matching the tool to the actual problem.
What a course typically involves
If we think you would benefit, the honest shape of it looks like this. First, an assessment of how your tongue rests, how you swallow, whether you seal your lips, and how you breathe at rest — set against what your teeth and bite are doing. From there, a tailored set of exercises, practised daily, reviewed and progressed over a period of months. It asks for consistency more than anything; the results come from the repetition, not from any single visit.
Because the discipline is delivered by specifically trained therapists, we are honest about who does what. Our role is the dental and airway-aware assessment — identifying whether muscle function is genuinely part of your picture, coordinating it with any orthodontic plan, and making the right onward referral to a qualified myofunctional therapist where a dedicated course is indicated. Integrative care, to us, means joining these threads up rather than pretending one clinician does everything.
Honest limits — what it will not do
Three boundaries are worth stating plainly, because overpromising is the main failing in this field.
It will not reshape an adult's bones. Adult facial structure is set; exercises change muscle function and habit, not skeletal form.
It is not a replacement for orthodontics where teeth need to be moved. It can support and protect an orthodontic result; it cannot straighten teeth on its own.
It is not a treatment for sleep apnoea. It is studied as one possible contributing element within a broader plan led by sleep-medicine specialists. If disrupted breathing in sleep is a concern, that assessment comes first, with the specialists who diagnose and manage it — we work alongside them, not in their place.
Naming these limits is not hedging. It is what lets us recommend the therapy confidently where it genuinely helps.
What it costs and how we plan it
We price honestly, which here means being clear that a dedicated myofunctional course is usually delivered by a specialist therapist and costed by them. Our part is the assessment and coordination. We begin with a free 20-minute discovery call, then a dental examination (£65) where clinically needed, which covers the dental and airway-aware review that tells us whether muscle function is part of your picture at all. If a full myofunctional programme is indicated, we set out the pathway and the onward referral clearly, in writing, before you commit to anything — so you are never paying for a course you do not need. Where orthodontic treatment is part of the plan, we cost that transparently too, against our published ranges.
Frequently asked questions
Does myofunctional therapy work for adults?
It may support specific things in adults — orthodontic stability, resting breathing and tongue patterns, and as an adjunct within wider airway care. It will not reshape adult bone or work as a stand-alone fix. The honest answer depends on whether muscle function is genuinely part of your picture, which is what an assessment establishes.
Can myofunctional therapy change my face shape?
Not the bone. In adults the facial skeleton is set. The exercises change how the muscles work and rest, which can affect posture and habit, but claims of "facial transformation" overstate what is possible. We are careful not to promise that.
Is it the same as mewing?
No. "Mewing" is an internet term for tongue-posture habits, often oversold. Myofunctional therapy is a structured clinical discipline delivered by trained therapists, covering tongue posture but also swallowing, lip seal, and breathing, with assessment and progression. We have a separate page, mewing explained by a dentist, that covers it honestly.
Can it help my child avoid braces?
In growing children, muscle function and airway are genuinely influential, and myofunctional input is increasingly part of early, airway-aware care. Whether it reduces the need for orthodontics depends entirely on the individual child — it is an adjunct, not a guarantee. We would assess rather than promise.
Do you provide the therapy yourselves?
We provide the dental and airway-aware assessment and coordinate your care; a dedicated myofunctional course is delivered by a qualified myofunctional therapist, to whom we refer where it is indicated. We are honest about who does what so the care actually joins up.
If you want an honest assessment
If you have read about myofunctional therapy and want to know whether it is relevant to you — or to your orthodontic plan — the useful next step is an assessment that looks at how your mouth actually functions, set against your teeth, bite, and breathing. From there we can tell you honestly whether it would help, and coordinate the right care if it would.
