How Does an Orthodontic Expander Work?
An orthodontic expander gradually widens the upper jaw by applying gentle pressure to the two halves of the bone, which don’t fully fuse until after adolescence. The device is typically placed against the roof of the mouth and includes a small screw that can be turned daily with a special key. This slow, steady pressure encourages the jaw to widen over time, creating more space for proper tooth alignment.
Expanders are most often recommended for children and young teens because their jawbones are still growing. However, in some cases, adults may also benefit from this treatment.
Benefits of an Orthodontic Expander
The tooth expander offers several key benefits for patients:
- Prevents overcrowding: By widening the jaw, the expander creates more room for incoming adult teeth, reducing the likelihood of crowding and the need for tooth extractions.
- Correct crossbites: When the upper teeth sit inside the lower teeth due to a narrow upper jaw, an expander can help correct this misalignment.
- Improves breathing: Expanding the upper jaw can improve airflow and help with breathing issues, particularly in children who suffer from obstructive sleep apnea.
- Supports a better bite: A wider jaw helps align the upper and lower teeth properly, leading to a more comfortable and functional bite.
How Do I Know If I Need an Orthodontic Expander?
Your orthodontist may recommend an expander if you or your child are experiencing one or more of the following issues:
Severe crowding
If there’s not enough room in the jaw for all the teeth to come in properly, an expander may be used to create more space.
Crossbite
If the upper teeth sit inside the lower teeth, it may indicate the need for jaw expansion.
Impacted teeth
In some cases, teeth may not erupt because they’re blocked by other teeth. Widening the jaw can help create room for impacted teeth to come in naturally.
If you’re unsure whether you need an expander, consult your orthodontist to determine the best course of action.
How Long Will You Need to Wear an Expander?
How long you will need to wear a mouth expander depends on the individual’s needs and the severity of the condition being treated. In most cases, the active expansion phase lasts about three to six months. After the desired expansion is achieved, the expander will remain in place for several more months to allow new bone to grow and stabilize the widened jaw.
Our experienced orthodontists will guide you through the process and determine the exact timeline for your treatment.
Caring for Your Expander
Taking proper care of your expander is essential for both comfort and effectiveness. Here are a few tips to help:
- Keep it clean: Brush around the expander thoroughly, as food particles can get trapped inside. Your orthodontist will provide specific cleaning instructions.
- Be mindful of food choices: Stick to soft foods, especially in the first few days, and avoid hard, sticky, or chewy foods that can damage the expander.
- Report any issues: If you experience discomfort beyond the normal adjustment period or notice any problems with the appliance, contact your orthodontist promptly.
Following these care guidelines will help your treatment progress smoothly and keep your expander in good condition.
