A dental post consisting of fibre-reinforced material with substantially uniformly directed fibers (8) and mountable in a tooth root canal for fixing a dental prosthetic structure on a tooth stump and a method for its fabrication. For improving the light conduction properties within the post, at least a fraction of said fibers (8) are adapted for light conduction within said post and said post comprises a tapered portion extending towards its second end (4), wherein at least a fraction of said light conducting fibers (8) extend from the first end (3) of said post to the circumferential surface (2) of said tapered portion. An advantageous fabrication method of the dental post comprises forming of a composite structure (1) of uniform cross-section with substantially uniformly directed light conducting fibers (8) in a pultrusion process and shaping of at least a portion of the circumferential surface of said composite structure (1) in order to provide a tapered portion extending towards the second end (4) of said composite structure.
