about 2 week ago I cracked a molar I was told I need to either have a root cannal if the crack is not too bad or have it pulled if it cannot be saved. about 4 hrs ago the lower half of my jaw started to fell numb and tingly can this also be a side effect of the tooth being cracked?
Dear Sir/ Madam, If there was a crack in the molar it needs an immediate attention as it is a primary tooth for mastication. Now you are feeling numbness and tingling sensation, this may be due to spread of infection to the nerve of the jaw passing near to the tooth. I suggest going to the dentist as soon as possible because it can be cured at this stage with proper investigations.
