I had crown done following the root canal treatment on 14th tooth 3 years ago due to a regular recurring abscess. After the root canal treatment and crown, i used to get abscess at exactly the same location every now and then but that time with no pain. A month ago the abscess recurred again after a long while, so i went to a dentist (a different this time since i have moved places). He suggested that the previous root canal was not done properly and that the crown had to be removed. After removal of the crown, and second root canal treatment, we compared before-and-after x-ray that clearly indicated the difference.
However during my first visit to my new dentist, he had pushed and popped the abscess, the next day i got up with temprature, headache and ill feeling that lasted a week. since i could make no connection between the temrature, headache and my ongoing dental treatment, i did not complain. but yesterday i went for a visit again because of a recurring abscess again, and this morning for the 3rd time i got up with headache, slight temprature, swollen neck glands and ill feeling.
I fear of infection being spread far deep inside the bone or elsewhere, would that be possible? and what steps should i follow? and finally would a head scan will help to see whether the infection has spreaded far up?
