Permanent numbness in lower chin following wisdom tooth extraction.

[belib]

I had a wisdom tooth removed about 30 years ago.  It was impacted and I was awake during the procedure.  A section of my chin and gum was affected by this procedure.  The numbness/ cold feeling subsided over the years, but never went away.  Recently, I had a cavity filled on the bottom back molar on the side where the numbness is.  The dentist gave me a shot in the back of my mouth to numb the area around the tooth he would be drilling.  This was about two weeks ago.  The sensations in my chin and gum area have intensified.  Feelings include numbness, coldness, and some pain after I eat.  Does anyone have any information about this?  Any assitance would be greatly appreciated.

Thank you for your advice.  I plan on calling the dentist this week and make him aware of the situation.  I hope that the intense sensations will decrease and the areas will feel like they use to (still numb).  In the past, I have had three fillings in other sections of my mouth.  These areas were never numb and were not affected by the block injections.  I never expected this.  I would have endured the drilling without the block.  Thanks again for the info.

Every dentist needs to make every patient aware of the possibility of a paresthesia whenever giving a mandibular block injection. The chances of it happening are usually slim but if the nerve running along the lower part of the jaw gets entangled with the root tips or if they should pierce the nerve or even graze it patients can have the numbness in the lip, cheek or tongue, or all of them. In some instances the paresthesia will gradually decrease and the patient will notice more feeling coming back in the area. Your dentist or Oral Surgeon should be made aware of your situation so they can monitor that for you, and if they have any recommendations for you, now would be the time
