The single tooth (12) or several teeth are screwed to a rectangular base (112) provided at the top of a bridge (11) to be inserted in the gap left after the extraction of either one tooth or several teeth. A cap (111) in the shape of the rear of the tooth (2) adjacent to the gap is positioned at both ends of the bridge (11) for being attached to the teeth (2) which do not have to be filed into a cone for being covered with crowns. Small extensions (121) following the shape of the gum surface protrude from the lower end of the artificial tooth (12) and can be locked in the space provided between the gum and the narrow lower ends of the adjacent teeth (2), protecting the bridge (11) from being removed unintentionally.
