It may go away, and it may not. You are going to have to wait to see if your nerve repairs itself, which is possible. I'm sorry about this happening to you and hope for the best.
The following regimen may help resume normal nerve function:
Nutritional supplements:
vitamin B1,B6,B12,folic acid, omega3 fatty acid, alpha lipoid acid.
Pharmacologic management:
Amitriptyline and/or gabapentin
Seeing a neurologist or Orofacial pain specialist who is experienced in managing traumatic trigeminal neuropathy is advised.
