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.
The tooth expander offers several key benefits for patients:
Your orthodontist may recommend an expander if you or your child are experiencing one or more of the following issues:
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.
If the upper teeth sit inside the lower teeth, it may indicate the need for jaw expansion.
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 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.
