Last summer I had a crown put in my back upper molar due to the dentist repeatedly messing up my tooth.  It triggered a strange pain in my jaw, headache and a constant sharp pain in the back of my skull when I swallow, laugh, cough, chew...pretty much any time.  I went to local medical clinic and they gave me an antibiotic and anti-inflamatory.  It went away about 10 days later.  It is now back as of last Monday.  Not sure what to do, where to go, etc...  Pharmacist says possible triad facial neuropathy.
Hi! Welcome to Chat Doctor. I read your query. Did this pain start only after placing the crown or was it there before too? And was RCT of the tootChatDoctorplete before placing crown? If this started after crown, I would suggest you go to your dentist and get the high points of that crown checked. At times disturbed occlusion level of crown leads to pain (more while chewing). In case there are none, get the crown removed and check if pain goes. If it persists, do get a radiograph of the tooth done to rule out any infection there. And if the pain is still there, I would suggest you to consult a neurologist for further tests. Hope the answer helps. Thank you.
