Palatal Expander



The palatal expansion procedure is used to widen or expand the upper jaw in the transverse direction. It is one of the craniofacial growth modifying techniques that can be used to treat a variety of issues in a growing patient.  A palatal expander is most often used for the correction of crossbites, but it can also be used to create adequate space for the eruption of crowded permanent teeth, thereby reducing the need for permanent tooth extractions.  Very importantly, widening of the upper jaw also has been shown to improve the airway which can significantly improve the quality of the child’s sleep and quality of life . Widening of the upper jaw also creates more space for the tongue, thus reducing tongue habits,  and in some cases improving speech.  It is most effective when used from ages  7-12, with earlier age deeming better results. It’s non-invasive and has very little to no discomfort.
