What Is A Palate Expander?

A teeth expander is an instrument that widens your mouth. It creates more room by gradually extending the jaw. It may sound a bit scary, but do not stress! Expanders can get used to fixing issues early on, so they do not become a bigger problem.

When Do I Need An Expander?

You will require a palate expander when your mouth falls into one of these three categories:

  • Crossbite
  • Crowding
  • Impacted teeth


You will require to wear an expander if you have a crossbite. When your upper jaw is narrower than the lower jaw, push the top back teeth inside the lower back teeth. The expander makes room for your teeth and helps get rid of the crossbite.

Crossbites get confused with underbites often. Crossbites are when the upper and bottom rows of teeth do not line up with each other. It can occur when adult teeth develop before your baby teeth fall out, or you sucked your thumb a lot when you were a kid.


One mote reason you may need an expander is if your teeth are overcrowded. It is when your teeth do not have sufficient room in your mouth. They may overlap or push on each other. Teeth expanders get used to creating space in your mouth. An orthodontist can inform by looking at your baby teeth if you have enough room for your incoming adult ones. Broadening the upper jaw with a palate expander ensure your teeth will come in without generating any problems.

Impacted Teeth

Teeth get impacted when a growing tooth gets blocked by other teeth. Expanders make room for that new tooth. Canines are the most commonly impacted teeth because of their position in your mouth.

What’s the Best Age for a Palate Expander?

Teeth expanders are most useful in a window. Children not completely grown can get the most advantage out of expanders, as they can adjust the jaw easier. The age limit is 13 – 14 for girls and 14– 16 for boys. Older children can also use an expander, but they may not be as compelling. If teeth do not have sufficient room to develop, this may drive other dental problems later on. It is best to detect and rectify these problems early in children so that the expander can be more effective.

Expanders For The Upper Jaw

There are two types of teeth expanders- one for the upper jaw and one for the lower. An upper jaw expander gradually expands the space in the top of your mouth by expanding your palate. Over time, the palate expander gets broad. Do not worry! Our orthodontists won’t enlarge it too much at one time! After the expander treatment is complete, sometimes there is a gap between teeth. It gets easily fixed with a retainer.

Expanders For The Lower Jaw

A lower jaw expander works a little differently. The expander moves your teeth directly instead. Lower expanders can also fix teeth that are overcrowded or tilting in too much by spreading out your lower teeth.

How Long Do I Wear It?

Typically, 1-3 weeks. Some patients need a longer, but not usually longer than six months. Sometimes the bones in your mouth take longer to adjust and need time to form.
