Adult Expansion & Functional Orthodontics
Sometimes better function starts with more room.
Arch width, tongue space and bite relationship are structural questions, not cosmetic ones. For some adults, creating room is a meaningful part of a broader airway and function plan. For many others, it isn’t — and we would rather tell you that than treat around it.

Why room matters
Space, posture and function are connected.
01
Tongue space
The tongue needs somewhere to rest. A narrow arch gives it less room at the roof of the mouth, which can influence where it sits during the day and at night.
02
Arch width
Width affects crowding, bite relationship and how the upper and lower arches meet — structural factors, not cosmetic ones.
03
Function
Chewing, swallowing, lip seal and nasal breathing all interact with the shape of the arches and the position of the jaw.
04
One factor among several
Structure is part of the picture. It sits alongside nasal patency, soft tissue, weight, sleep position and medical factors — none of which expansion addresses on its own.
The distinction that matters
Dental expansion and skeletal expansion are not the same thing.
A great deal of confusion — and a fair amount of marketing — comes from blurring these two.
Dental (alveolar) expansion
Teeth and the bone immediately supporting them are moved outward. This changes arch form and tooth position. It does not widen the underlying skeletal base, and how much movement is appropriate depends on your bone, gum tissue and starting position.
Skeletal expansion
Approaches aimed at the bony base itself. In adults the midpalatal suture is typically fused, so skeletal change generally requires appliances and techniques beyond conventional orthodontics — and often specialist involvement.
Surgically assisted approaches
Some adults are candidates for surgically assisted or device-assisted skeletal expansion. These are directed by oral and maxillofacial surgeons and other specialists. Our role is evaluation, coordination and dental care around the procedure.
Clear aligners and conventional orthodontics
Aligners and braces move teeth. They can improve alignment and, within limits, arch form. They are not a skeletal expansion technique, and presenting them as one would be misleading.
Clear aligners
Dental Expansion with Candid Clear Aligners
- Aligner systems are one way to move teeth when tooth movement is what the plan calls for
- Expansion with aligners is possible even in adults, but there are limitations
- When a case is beyond what tooth movement can achieve, we say so and refer
Adult considerations
Adults come with history.
Treatment planning for an adult accounts for what has already happened to the mouth — not just where the teeth are today.
- Bone volume, gum tissue health and periodontal condition
- Existing restorations, missing teeth and overall dental stability
- Jaw joint and muscle comfort, evaluated before and during treatment
- How the bite will function at the end, not only how it will look
- Retention — arch changes need a plan for holding them
When we refer
Knowing the limits of what we provide.
Skeletal change in adults often calls for orthodontic specialists, oral and maxillofacial surgeons, or device-assisted techniques we do not provide. When that is what your situation needs, we say so and coordinate the referral.
We also refer for medical sleep evaluation, ENT assessment of nasal obstruction, and any concern that belongs outside a dental office.
How it goes
Five steps, at your pace.
01
Consultation
We listen to what you have noticed — breathing, sleep, jaw comfort, crowding, bite changes — and to any diagnosis or testing you already have.
02
Comprehensive evaluation
Arch form, bite relationship, tongue space and posture, nasal breathing, jaw joints and, where appropriate, imaging.
03
Discussion & coordination
We explain what dental movement can and cannot achieve for you, and coordinate with your physician, ENT or a specialist when the plan calls for it.
04
Treatment
Orthodontic or expansion care delivered at a pace guided by your tissue response and comfort, alongside supportive care such as myofunctional therapy where indicated.
05
Retention & reassessment
A plan for holding the result, with periodic review of bite, jaw comfort and function. Whether breathing or sleep improved is assessed with your physician.
Setting expectations
What we can and can’t promise.
We cannot promise a specific amount of width, a fixed timeline, a change in your sleep study, or a particular facial result. Response varies with bone, tissue, technique and individual biology.
What we commit to is an honest evaluation, a plain explanation of what tooth movement can and cannot accomplish for you, coordination with the right specialists, and a willingness to recommend no treatment when that is the right answer.
Costs & coverage
Reviewed before anything starts.
Orthodontic and expansion costs depend on the approach, the length of treatment and whether specialist care is involved. Coverage varies by plan.
Our team reviews your benefits and gives you expected costs in writing before treatment begins. We do not quote figures before we know your plan and your case.

Explore Myofunctional Therapy →TMJ & Jaw Pain
Jaw joint and muscle symptoms are evaluated before and during any change to the bite.
Explore TMJ Care →Alpine, Utah
Functional orthodontics for Utah County adults.
Alpine Airway Wellness serves adults from Alpine, Highland, American Fork, Lehi, Cedar Hills, Pleasant Grove, Draper and throughout Utah County who want orthodontic care considered in terms of function and breathing — with clear boundaries about what belongs with a physician or specialist.

Clinically reviewed by Dr. Brittany Johansen. This page is general education, not a diagnosis or a treatment plan.
We see patients at our Alpine, Utah office, including families from Highland, Cedar Hills, American Fork, Lehi and across Utah County.
