A fiber optics dental post includes a resin body and plural fiber optics center shafts wherein the resin body includes an outer peripheral face, a receiving irradiation portion, and a bottom each of the fiber optics center shafts pierces through and is fixed in the resin body, and has a receiving irradiation end and a light-guide irradiation end each receiving irradiation end placed on the receiving irradiation portion of the resin body is used to receive the light irradiating on the receiving irradiation portion, and each light-guide irradiation end is respectively placed on the outer peripheral face and at the bottom of the resin body, thus the light received by each receiving irradiation end is propagated to the outer peripheral face and the bottom of the resin body through the light-guide irradiation end for irradiation, so as to effectively enhance the adhesion strength of the dental post.
