Orthodontic expanders are devices used to widen the upper jaw, helping to correct dental crowding, narrow arches, and bite problems like crossbites. These appliances gradually expand the palate, allowing more space for the teeth to align properly.

The expander is typically fitted to the upper molars and works by applying gentle pressure to the bones of the upper jaw, encouraging them to widen. The treatment is most effective during childhood and adolescence when the bones are more malleable.

Orthodontic expanders can be fixed or removable. Fixed expanders are worn 24/7, while removable ones can be taken out for cleaning and eating. Patients are instructed to use the appliance as directed to achieve the best results.

With proper use, orthodontic expanders can create the space needed for proper alignment and ensure a functional bite, enhancing both appearance and oral health.
