After amoxicillin and endo retreating tooth, it felt better and fever gone, but 2 days after ending antibiotics, infection returned with intensity, spread along jawline into nearby tooth, causing that tooth to then also need a root canal. I was put back on the same dose of amoxicillin, then tried
clindamycin for a few days, but infection continued to spread - a large red hot lump (tablespoon sized) formed on my jawline, just under the 2 affected teeth.
