1. A root canal filling composition for placement in a tooth root canal, the root canal filling composition comprising an elongate glass-fibre post with a first end and a second end, an apical stop which is made of a physiological material and is arranged at the first end, and a filling material, which surrounds the glass-fibre post over its entire surface at least in some regions, wherein the filling material comprises a dentine-adhesive filling material, further wherein the apical stop has a length of not more than 1/10 of the length of the glass-fibre post to thereby allow limiting of cavity formation adjacent the apical stop and allow the tooth to be stabilized by the elongate glass-fibre post adjacent the apical stop.
