How long takes a alveolar nerve damage to heal?

Nerve damage heal: There are different type of nerve damage. If it is just demyelinating injury (damage the peel of nerve), it would need a few weeks to heal after the etiology removal. If axonal damage, the nerve need regrowth from spine about 2-3 mm per day if the pathway soft tissue (frame of nerve) is still intact. It is almost impossible to full recovery nerve function if both axon and frame are messed up.
