What causes numbness in lip and chin while having tooth pain?
Patient: My bottom tooth 5th one from the left was hurting for a few days. The pain shot up into my neck and down into my shoulder where my arm was giving out. My jaw began hurting and now the pain is gone On and off but my bottom lip and chin are numb and have been for 3 days now:/ Doctor: helllooo....numbness is due to the infection at  the root surface of the tooth ..it is pressing ur nerve to the lower lip..actually nothng much to worry in this..take amoxicillin and metronidazoleand diclofenac ...for 5 days...go to dentist ...and get the root canal done....pain and numbness will be reduced within few days time...and dont wait for long..sometimes it can spread to ur neck n all below the tongue etc...meet dentist and get it done...dont get panic ..be cool and have a nice day!!!
