This disclosure discloses an oral cavity observation instrument, relating to the field of dental examination technology. The specific implementation scheme is as follows: a chamber and a working surface are formed within the outer shell of the main body of the oral cavity observation instrument, with the working surface located on one surface of the chamber; it also includes a camera module and at least one light source; the at least one light source includes a violet light source; the camera module and the at least one light source are respectively disposed within the chamber at positions where they intersect with the working surface, the acquisition window of the camera module faces outwards from the chamber to ensure that the camera module can acquire images outside the chamber; the illumination direction of the at least one light source faces outwards from the chamber to ensure that the at least one light source can emit illumination light outwards from the chamber; a controller is also disposed within the chamber, the controller being used to suppress the original blue pixel information in the original tooth image acquired by the camera module under violet light illumination; and to regenerate a target tooth image based on the information of the original red and green pixels in the original tooth image.
