Q. Hello, I had an accident on ll5 and porcellain crown i bit down hard and i think i trapped a nerve…..had ll5 removed and same pain went to ll4 – sensitive to hot and cold and my ear pops and clicks, after 2 x colds the symptoms i experience are a sucking sound, toxins, blocked ear and a sensitive ear and tooth…i take 2 x antibiotics and it helps but do you think root treatment would help? nothing shows on xray but the tooth cracks on biting….I am seeing a specialist but they don’t do anything either Thanks
