1. A non-transitory computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
making a comparison between first image data of at least a portion of a dental arch and second image data of at least the portion of the dental arch;
determining, by a processing device, a plurality of differences between a first representation of at least the portion of the dental arch in the first image data and a second representation of at least the portion of the dental arch in the second image data;
determining, by the processing device, that a first difference of the plurality of differences is attributable to tooth movement;
determining, by the processing device, that a second difference of the plurality of differences is attributable to tooth wear to one or more teeth on at least a portion of the dental arch; and
generating, by the processing device, a third representation of at least the portion of the dental arch that is a modified version of the second representation, wherein a visual indication of the tooth wear is provided in the third representation.
