1. A system comprising:
a memory; and
a processing device operatively connected to the memory, the processing device to:
make a comparison between a current image of an oral cavity of a patient and one or more previously received images of the oral cavity of the patient, the current image and the one or more previously received images having been generated by an intraoral scanner;
determine an amount of overlap between a current field of view of the intraoral scanner and topography scans of the oral cavity based on the comparison; and
output a warning indicator associated with a positioning of the current field of view of the intraoral scanner responsive to determining that the amount of overlap fails to meet or exceed an overlap threshold.
