Had dental filling of left lower molar two weeks ago. Dentist had an extremely difficult time numbing me never got it fully numb. Hit live nerve while filling tooth. Two days later face swelled and severe pain followed. Saw dentist 4 days later filed down filling and placed me on antibiotics and pain killers. Going on 3 weeks swelling of face continues and now can't open mouth without severe pain following ears hurting sometimes and headaches and uncontrollable coughing dentist is very nonchalant .
