The invention relates to a multi-part tooth implant with at least a proximal implant part and a distal implant part that are to be connected to each other such that a connection site is obtained when the two implant parts are in the connected state. An annular sealing element is arranged at this connection site and, in the fully assembled state of the tooth implant, is clamped between mutually opposite sealing surfaces, namely a sealing surface of the proximal implant part and a sealing surface of the distal implant part, such that the sealing element has an outer surface portion that forms part of the outer contour of the tooth implant. The two sealing surfaces initially approach each other in a direction oriented outwards from a central longitudinal axis of the tooth implant. The sealing surfaces merge into outer surfaces of the tooth implant at the place where, in the outer contour of the fully assembled tooth implant, a surface portion formed by the sealing element in each case adjoins a surface portion formed by the respective implant part. These outer surfaces move away from each other in the outwardly oriented direction.
