Peripheral nerves can re-grow (central ones can't).
No-- Nerve cells are one of the few kinds of cells that never regenerate or regrow.

Trigeminal nerve
Nerves are composed of a bunch of small fibers called axons. If that axon is allowed to regrow it will regrow at an average rate of 1-2mm per day. Some nerves have axons that may grow faster or slower. This is true only if the injured nerve is allowed to regrow, i.e. if is severed or compressed without any sort of decompression it may not be able to completely regrow. The 2 main factors that determine whether or not an axon will regrow are (1) if the soma (i.e. cell body) is still alive and attached to the axon, and (2) if the endoneuriium which forms the tube that the axons travel down is still intact. It it is allowed to regrow the length of time depends upon how much new regrowth is required. If you injured a nerve in your lumbar spine (i.e. your low back), that may be 1 meters worth of growth to get to the feet. At 1-2 mm per day, that may take up 500 to 1000 days. If you injured a nerve at your wrist (as occurs with carpal tunnel syndrome and the median nerve), that may be 5 cm and could take 25-50 days to completely regrow.
Stem cells have the potential to differentiate into various cell types, including nerve cells, which can help repair damaged nerves. When administered in the specific damaged area, stem cells can promote nerve regeneration and overall healing, aiding in the restoration of function in the affected area. However, the success of such treatments may vary and is still an area of ongoing research and clinical trials.
Damage to the facial nerve (cranial nerve VII) can result in drooping of the mouth on one side, a condition known as facial paralysis or Bell's palsy. This nerve controls the muscles of facial expression, including those involved in smiling, frowning, and closing the eyes.
Yes, the peroneal nerve has the capability to regenerate if it is injured. The rate of regeneration can vary depending on the extent of the injury and individual factors. Physical therapy and other treatments may be recommended to support the regrowth process.
Marginal mandibular branch of the facial nerve.
Yes, the lining of the mouth is damaged and that produces pain. The mouth and lips have a very large number of nerve endings.
The trigeminal nerve (cranial nerve V) is of particular interest to dentists and dental patients because it innervates the muscles of mastication and is responsible for providing sensation to the face, mouth, and teeth. Issues with the trigeminal nerve can lead to problems with chewing, swallowing, and feeling in the face and mouth.

Unfortunately, gum tissue lost due to recession or gum disease is generally permanent. In severe cases, surgery can be performed where tissue from another part of the mouth, typically the palate (roof of the mouth) is transplanted to replace lost gum tissue. This surgery requires a high level of skill from the surgeon.
