Hearing that you may need a palatal expander often raises questions. What does it do? Will it be uncomfortable? How long will it take?
At House of Orthodontia in Brooklyn, expansion appliances are a proven and effective option for adults and teens seeking to correct jaw imbalances, create space for proper alignment, or enhance breathing.
This treatment is not just for children. With advanced digital planning and precision appliances, jaw expansion can now be achieved comfortably for adults as well.
This guide explains what to expect during treatment and includes expert insights to help you feel confident and informed.
What Is a Palatal Expander?
A palatal expander, sometimes called a jaw widening device, is a small orthodontic appliance that gently broadens the upper jaw to improve bite alignment, balance, and symmetry. It corrects issues such as crowding, crossbite, or a narrow arch that prevents teeth from fitting properly.
The appliance works by applying light, steady pressure to the mid-palatal suture (the natural joint in the roof of the mouth). As new bone forms, the upper jaw becomes wider and more proportionate.
For adults, this type of expansion can improve nasal airflow, relieve jaw tension, and enhance the long-term results of braces or Invisalign.
What to Expect When Getting an Expander in Brooklyn, NY
At House of Orthodontia, treatment begins with a 3D digital scan of the mouth. This technology allows for precise measurements and a comfortable, custom fit without messy impressions.
Once the appliance is ready, your orthodontist will explain how it works, what each part does, and how to activate it at home if needed. The process is straightforward, and most patients adapt faster than expected.
Follow-up visits are scheduled to make sure the upper jaw expansion progresses evenly and comfortably.
How the Expansion Appliance Is Placed
Placing an upper jaw expander is quick and comfortable. The appliance is bonded to the upper molars with a dental adhesive during a short visit. Once in place, the orthodontist gently activates it to start the widening process.
Some patients receive a small key to make controlled turns at home. Each adjustment moves the two halves of the upper jaw slightly apart, creating a light pressure that fades within minutes.
Turn the key at the same time each day to maintain consistency and make progress easy to track.
What to Expect in the First Few Days
The first few days after placement involve a short adjustment period. It’s common to feel:
- Mild pressure in the upper jaw
- Temporary changes in speech
- A slight increase in saliva
These sensations are normal and fade within a week. Eating soft foods, staying hydrated, and practicing speech can help the mouth adapt faster.
Most patients stop noticing the appliance after the first week. Consistent hygiene and patience are key to comfort.
Aftercare and Cleaning Tips
Proper care keeps your expansion device clean, effective, and comfortable.
Daily Care Routine
- Brush carefully after every meal, focusing on the appliance.
- Rinse with water or a mild mouthwash to remove food particles.
- Use a water flosser to clean hard-to-reach areas.
- Avoid sticky or hard foods such as caramel, nuts, or gum that could loosen the appliance.
Use an interdental brush to clean under and around the expander. This small step prevents irritation and buildup.
How Long You’ll Need to Wear the Appliance
Every smile is unique, but most adults and teens wear an expansion appliance for about four to six months. The first few weeks involve active widening, followed by a stabilization phase that allows new bone to strengthen.
Once the desired expansion is achieved, the appliance remains in place briefly to secure results. Afterward, braces or aligners may be used to refine alignment.
Wearing the device for the full recommended time helps the new bone stabilize properly for lasting results.
Benefits Beyond Straighter Teeth
A palatal expander offers benefits that go far beyond straightening. Expansion can:
- Improve airflow and nasal breathing
- Correct crossbites and balance the bite
- Create space for proper tooth alignment
- Enhance facial symmetry and structure
- Reduce strain on the jaw joints
Many patients experience easier breathing, reduced tension, and improved comfort after treatment. Expansion also makes orthodontic adjustments more predictable and stable in the long term.
Even for adults, early evaluation can prevent complications and simplify future treatment.

No. A brief feeling of pressure or tingling is normal and fades quickly.
Can adults benefit from a jaw expander?
Yes. Modern orthodontic techniques make expansion safe and effective even after growth is complete.
