Expansion appliances
What is it?
Expansion appliances are orthodontic devices used to gradually widen the upper or lower jaw to create proper space for teeth alignment and improve bite function. These appliances are commonly used in growing children and teens, but in some cases can also benefit adults as part of a comprehensive orthodontic treatment plan.
​
At our Calgary dental clinic, expansion appliances are carefully selected and customized to support healthy jaw development and long-term orthodontic success.
Who it’s for:
Expansion appliances may be recommended for:
-
Children and teens with narrow dental arches
-
Patients with crowding or lack of space for teeth
-
Bite issues such as crossbite
-
Jaw alignment concerns
-
Patients preparing for braces or Invisalign
-
Anyone seeking orthodontic care in Calgary
Early intervention with expansion appliances can help guide proper jaw growth and reduce the need for more complex treatments later.
How the procedure works:
-
Orthodontic evaluation
We assess jaw width, bite alignment, and tooth spacing using exams and digital imaging.
-
Custom appliance design
A personalized expansion appliance is created to fit comfortably and effectively.
-
Gradual expansion phase
The appliance gently widens the jaw over time through controlled adjustments.
-
Stabilization & next steps
Once expansion is complete, the appliance is stabilized and followed by braces or aligners if needed.
Comfort and safety
Expansion appliances are designed to apply gentle, gradual pressure for safe and effective results. Patients may experience mild pressure or tightness during adjustments, which typically resolves quickly.

Our clinic uses modern orthodontic techniques and follows strict sterilization and infection control protocols to ensure patient safety and comfort throughout treatment.
