1. A non-transitory computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
generating one or more parametric functions associated with tooth color based on color data for teeth from a first image of a mouth, wherein each of the one or more parametric functions comprises a first variable for a first image axis and a second variable for a second image axis;
receiving image data comprising new contours of the mouth, wherein one or more of the teeth have a different position in the image data than in the first image; and
generating a new image based on the image data and the one or more parametric functions, wherein a shape of the teeth is based on the image data and a color of the teeth is based on applying the one or more parametric functions to at least a portion of the image data.
