1. An intraoral scanning system, the system comprising:
a hand-held wand having at least one camera image sensor and a plurality of light sources, wherein the light sources are configured to emit light at a first spectral range and a second spectral range, wherein the second spectral range is within near-infrared (near-IR) range of wavelengths; and
one or more processors operably connected to the hand-held wand, the one or more processors configured to:
receive scan data of a patient's dentition taken with the hand-held wand, wherein the scan data comprises surface scan data and near-IR scan data;
generate a three-dimensional (3D) model of one or more teeth using the surface scan data;
detect, from at least the near-IR scan data, one or more caries;
correlate the one or more caries to the 3D model to associate a location of the one or more caries with a corresponding location in the 3D model; and
display the 3D model and one or more near-IR images correlated with the 3D model showing one or more internal features including the one or more caries.
