In this paper, we investigate the dynamical entanglement properties between an effective two-level atom and a field in generalized photon-added pair coherent state in the Jaynes-Cummings model under the influence of a damping effect. Besides, we introduce a field-atom entangled state applied for quantum teleportation of an unknown atomic state from a sender to a receiver which geographically distant. We use an average fidelity criterion to quantify this quantum teleportation process. In addition, we also compare the results in two cases with and without the damping effect. The results have shown that the dynamical entanglement and quantum teleportation process are influenced by the damping parameter.
