1. A system comprising:
an optical probe with a sensing face, the optical probe to emit optical signals and receive reflected optical signals; and
a computing device, coupled to the optical probe, to:
receive intraoral scan data of a tooth, the intraoral scan data comprising first optical scan data and second optical scan data;
process the received intraoral scan data to adjust the first optical scan data associated with a sub-gingival surface of the tooth based on the second optical scan data associated with a material covering the sub-gingival surface of the tooth; and
generate a three-dimensional model that includes the sub-gingival surface of the tooth using the adjusted first optical scan data that is associated with the sub-gingival surface of the tooth.
