Reverse overjet occurs  when the lower jaw is 'oversized', or the upper jaw is undersized or a combination of both.  This usually results in the front teeth biting the wrong way around.  Reverse overjet can cause excessive wear to the surfaces of the incisor teeth and may be potentially damaging to growth and long term function of the jaw joints. The jaw growth discrepancy often worsens in the late adolescence and definitive treatment for this problem is often deferred until growth has slowed or stopped. Excessive lower jaw growth is very commonly associated with facial asymmetry because the lower jaw tends to grow more on one side compared to the other
