Hi From your symptoms,it seems one of your tooth on the lower side may be infected.Pain in the lower teeth may be felt in the upper teeth as well and is called as referred pain. Do you also have sensitivity to hot /cold? You need to get check up and x rays done to pinpoint the causative tooth. Don't wait for it to get worse! Good luck.

You probably have a deep cavity in a tooth that needs immediate attention for complete resolution of your symptoms.... nonetheless, a dentist who performs a proper clinical examination will be in the best position to make the correct diagnosis and advise you with the right treatment options..... Regards....

Hello..broken tooth may be due to decay or to the extent of vital tissue(pulp) which is causing pain.kindly visit nearby dentist to locate the pain by clinical and radiographic examination and treatment.

Broken teeth need attention as to why the tooth got broken .generally posterior or back teeth get broken because they are weak due to dental caries.ur case seems to be the same. tooth got weakened by caries n broke off .if u had shown it to the dentist back then,pain would not be there now.but now also its not too late go n consult a dentist in your area who would give u the right treatment option based on the clinical examination.

From what you have explained it looks like some of your teeth is decayed and the infection has reached the pulp..kindly show to the dentist and get it treated..so that it can be saved..do not delay..tc
