Sometimes, we need the “bigger picture “ and many small intraoral dental x-rays do not give us all of the information that we want. For example, if we need to see roots or angles of teeth that the smaller dental x-rays simply do not show. Other times we need to evaluate the angulations of teeth for orthodontics or for extractions. In these cases, we need a dental panoramic x ray. Panoramic X-rays show the big picture, without all of the detail of the small ones.
