I recently had my wisdom teeth removed 8 days ago.  The top, inner left side of my mouth is still numb and Im getting a little worried.  How can I tell if the damaged nerves are healing?  I have been feeling tingling sensations in the roof of my mouth for the past four days.  Is that a good sign?
Thanks for using Chat Doctor. Read your query. The numbness is due to prolonged anesthesia which usually happens due to any injury to the nerve during injection or due to trauma to nerve during the extraction. This numbness usually gets better with time, and you just have to relax. Usually the time cannot be predicted for this as it takes its own course. Just relax, take a healthy diet, and you can consult your local doctor and take vitamin B and C supplement, or Erosion tablet. Massage the gums and use warm saline gargling. You will have your senses back and will have a normal feeling. Do continue with salt water gargling. Hope this was helpful. Thanks and regards.
