Orthodontic treatment is about more than creating a straight smile. The development of the upper and lower jaws, width of the dental arches, position of the teeth, tongue posture, and overall facial growth can all influence how the mouth functions.
At Dentistry of Hockessin, we take a comprehensive approach when evaluating growing patients with concerns involving narrow arches, crossbites, crowding, jaw development, and other functional issues.
When appropriate, orthodontic expansion may be incorporated into a patient’s treatment plan.
What Is Palatal Expansion?
A palatal expander is an orthodontic appliance designed to widen the upper dental arch.
Expansion is most commonly considered during childhood and adolescence, when the upper jaw is still developing. Depending on the patient’s age and anatomy, different types of expansion may be appropriate.
Expansion can be used to address certain orthodontic problems such as:
- Narrow upper arches
- Posterior crossbites
- Significant dental crowding
- Lack of space for erupting teeth
- Certain transverse jaw discrepancies
Why Consider Expansion?
A properly developed upper arch provides space for the teeth and allows the upper and lower arches to coordinate more appropriately.
For selected growing patients, expansion may:
- Correct certain crossbites
- Increase available arch width
- Create space for developing permanent teeth
- Improve coordination between the upper and lower arches
- Reduce dental crowding in certain situations
- Support more balanced dental and facial development
In some patients, expansion may also be considered as part of a broader evaluation of airway-related concerns.
Orthodontics & The Airway
Airway health is complex and involves much more than tooth position. Nasal anatomy, tonsils and adenoids, tongue posture, skeletal development, soft tissues, sleep habits, and other medical factors can all contribute to breathing and sleep-related problems.
Orthodontic treatment may be one component of a multidisciplinary approach for appropriately selected patients.
We do not view orthodontic expansion as a universal treatment for snoring, sleep-disordered breathing, or sleep apnea. Instead, we evaluate each patient individually and coordinate with appropriate medical professionals when additional evaluation is indicated.
Who May Benefit From An Expansion Evaluation?
An orthodontic evaluation may be appropriate for a child with:
- A narrow upper dental arch
- Posterior crossbite
- Significant crowding
- Lack of space for erupting permanent teeth
- Certain jaw development concerns
- Oral breathing concerns
- Other developmental or functional concerns identified during examination
The presence of one of these signs does not automatically mean expansion is necessary.
How Expansion Treatment Works
A palatal expander is typically attached to the upper teeth or other supporting structures and gradually applies pressure to widen the upper arch.
The exact appliance, activation schedule, and duration depend on the patient’s age, skeletal development, diagnosis, and treatment goals.
After the active expansion phase, the appliance may remain in place for a period of stabilization while the surrounding tissues adapt to the new position.
Airway-Focused Orthodontics In Hockessin, Delaware
Our goal is to evaluate the entire orthodontic picture, not simply straighten teeth.
For children and adolescents with developing jaw or arch-width concerns, early evaluation can provide valuable information about whether expansion or another orthodontic approach would be beneficial.
