  We study the pairing dynamics of polar states in a single species p-wave
superfluid Fermi gas following a sudden change of the interaction strength. The
anisotropy of pair interaction together with the presence of the centrifugal
barrier results in profoundly different pairing dynamics compared to the s-wave
case. Depending on the direction of quenches, quench to the BCS regime results
in a large oscillatory depletion of momentum occupation inside the Fermi sea or
a large filling of momentum occupation. We elucidate a crucial role of the
resonant state supported by the centrifugal barrier in the pairing dynamics.
