There are several things an orthodontist may suggest when seeing a child. They may suggest a palatal expander, early interceptive treatment, baby tooth removal, or other things. A palatal expander is often used when the patient is still growing. This device in younger patients may reduce the need for extraction of permanent teeth or prevent teeth from impacting. Cases that are not corrected in growing patients may require surgery down the road or lead to abnormal wear and tear on teeth.
