When you think of orthodontic treatments, you probably think of braces.
While this is one of the most common solutions for a misaligned bite, less well-known options like palate expanders still have their place in select treatment plans.
If you think you might need to explore this avenue, you’re probably wondering about the average cost of a palate expander.
Let’s talk about expander braces cost, factors that impact the final bill, and how Ortho Co. can help you achieve the smile you’ve always wanted.
What is a palate expander?
A jaw expander is a metal or acrylic appliance that expands the upper palate to create more room for impacted or crowded teeth.
This is an alternative to removing teeth, and often sees excellent results in children, although palate expanders may be recommended for adults on a case-by-case basis.
Palate expanders are usually recommended for children with:
- Crossbites (a scissor-like bite that can increase tooth wear, strain jaw muscles, and disrupt proper biting function)
- Crowding
- Impacted Teeth (when teeth are blocked by others and unable to emerge)
- Facial asymmetry (Crooked smile due to small upper jaw)
The dental expander is placed by an orthodontist. Each day or week throughout the treatment process, a “key” is used (either by the parent or the patient) to widen the expander, forcing the dental arch outward.
This treatment method takes an average of nine months.

- Treatment Complexity : Cases involving severe crowding, crossbites, or impacted teeth may necessitate more complex treatment plans, increasing costs.

Additional expenses & hidden costs of jaw expander
Like most orthodontic treatments, jaw expanders are a financial undertaking. The best thing you can do for yourself (and your wallet) is to go in with a clear head and eyes wide open.
Not all orthodontists will list prices upfront. When you’re receiving projected costs, make sure you have a clear idea of what is included in palate expander dental cost and what will be an additional expense.
Here’s what you can expect to pay for the aspects of treatment that are sometimes left off the initial bill:
- Consultation and diagnostic records : Initial exams, X-rays, and impressions can cost between $90 to $300.
- Adjustment visits : Regular checkups during the expansion phase often included in the overall price, but some offices may charge extra, averaging $50–$150 per visit (at Ortho Co. we offer an all-inclusive package so no additional hidden fees for extra visits).
- Removal of expander : Some providers charge a fee for removal, typically $200–$400 (we do not charge at Ortho Co.,)- it’s all part of your treatment fee.
- Retainers and follow-up care : After expansion, retainers might be necessary to maintain results, costing $200–$500.
