<s>[INST] M y wife had tooth ach before . dentist cleaned and filled her tooth now there is not much pain she has sharp sensation arising out of her chin and face dentist says this is no more teeth problem this is nerve problem today I observed some of the nerves from inside chin are visible and sullen. Kindly advise and your phone no. is not given in internet thanks albert gomes [/INST] Hello and welcome to Chat Doctor forum, according to the history presented by you, I would like to inform you that your wife is experiencing pain or even sharp sensation due to a faulty restoration, sometimes the filling is too high that when the patient tries to close his /her mouth, sharp shooting pain occurs. But as you said that your dentist as already examined, then I would recommend you to get a second opinion also, because until I check the tooth clinically, i won't be able to give you an accurate diagnosis. Sometimes, even the infection within the tooth if not removed properly prior to the filling can cause pain n swelling, therefore kindly visit a specialist soon, i wish your wife good health, thank you for writing to Chat Doctor. </s>
