Intraoral Cameras. At Legacy Smiles of Southern Arizona, we understand how difficult it is sometimes for our patients to fully understand the condition of their teeth in the same way we do. To assist us in the diagnosis of our patients' dental health and as an educational tool, we use an intraoral camera. An intraoral camera is a small, state of the art dental device that looks like a pen. This "pen-like" device allows our patients to see exactly what we see is happening in their mouth.
