1. A system for taking images of a patient's teeth for tracking a progress of an orthodontic procedure, the system comprising:
a mobile device holder comprising one or more adjustable stops configured to provide a compressive force on a mobile device placed in the mobile device holder in order to prevent movement of the mobile device within the holder;
a cheek retractor coupled to the mobile device holder;
a non-transitory computing device readable medium having executable instructions that are executed by a processor to cause the mobile device to perform a method comprising:
providing, via the mobile device, a user interface; and
outputting an indicator, from the user interface, indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.
