I had a very bad toothache for about 3 days and didn t understand why because the tooth that was so painful was on that had a root canal and crown place over it over a year ago. So I went to the dentist and they found a huge infection in that tooth and that it had reinfected itself. They put me on clyndamiacin and Iv been taking that four about four days I m not sure if its helping my tooth gums and face are still very sore and swollen and its followed by a fever of 101 just feel very weak and tired and wanting to no if there is a possibility the infection is getting worse or spreading?
Since the tooth has got re infected it needs to be re treated. Since the area that is the tooth is closed. It must be opened through the canal i;e redo act so that Chat Doctor.  Trust me
