An Expander for teeth is an orthodontic device that is used to expand the jaw. The device is used widely in dentistry, especially for orthodontic treatment purposes. The main aim of the device is to correct different orthodontic problems.

So, a question may arise as to why the expansion of the jaw is required. Sometimes, for the constricted upper or lower jaw, different types of malocclusions, mainly crossbites, occur. A crossbite is the malalignment of upper and lower teeth and the inability of an individual to have a proper bite.

The dental expander is used to correct this problem mechanically without the help of any surgery. This is the most convenient way to correct posterior crossbites and help a patient have a correct tooth alignment.

Dental Expander is an active orthodontic appliance. An active orthodontic appliance is any appliance that produces force into the south to bring certain changes. There are many active orthodontic appliances including Hawley’s appliances, Springs, Expanders ETX.

The expander is fit into the palate of the patient. When it is well adapted, the dentist activates the dental expander through a screw. As a result, the expander starts giving force to the jaw. With optimal orthodontic force, the dental expander succeeds in bringing the desired expansion in the jaw.
