A dental camera is an intraoral viewing device, mostly including a handle and a mirror, fixed to a distal end of the handle, for insertion into the mouth of a patient, such that a first image of the inside of the mouth is viewed by reflection from a surface of the mirror. An image sensor inside the handle receives a second image of the inside of the mouth along a beam axis passing through a plane defined by the surface of the mirror, and the dental camera generates an electronic image responsive thereto.
