Dental expanders are orthodontic devices used to widen the arch of the mouth. They are typically recommended when patients do not qualify for conventional orthodontic braces. Expanders are usually worn for several months before braces are applied.

Expanders gently widen your upper or lower jaw. They do this by separating your two upper molars, which will give the other teeth in your jaw room to breathe and move. They apply gradual pressure on the roof of the mouth/palate. This widens the arch and creates more space for teeth to move into. 

What Procedures Require the Use of an Expander?

Expanders are often required in orthodontic treatment to set the stage for future orthodontic treatment. An expander is often required in orthodontic treatment when a child’s upper and lower jaw do not align well with each other. This misalignment can be the result of a narrow upper jaw, a narrow lower jaw, or both. For children, expansion is usually carried out between the ages of 7 and 9. For adults, expansion is typically carried out between the ages of 18 and 22. To determine if this option is right for you, please get yourself thoroughly examined by our dentist.

By expanding the upper jaw, we are able to create more space for crowded teeth. Similarly, by widening the lower jaw, we can create room for teeth that are protruding.

What to Expect From Treatment With an Expander?

Once the expander has been put into place, the dentist will instruct the patient on how to use the appliance. The patient will need to place the expander in between the upper and lower teeth with the metal arms extending outwards. Then, the tray needs to be filled with a small amount of pressure for 15 to 20 minutes each day. The patient should continue with this treatment plan until their expanders are removed.

The length of time needed for treatment will vary from patient to patient, but the average length of time needed is six months. Once the treatment is complete, the patient will have a wider smile.

How Long Does It Take to Recover From the Procedure?

The recovery time for dental expanders varies. However, most patients can return to their normal activities immediately. If you’re at all worried about recovery time, it’s a good idea to ask our dentist what to expect and what you can do to help yourself heal faster.
