Hi Bryanna,

Thanks so much for your reply. I don't have any other root canals in the area (or in my mouth for that matter) although the tooth directly adjacent to the extraction has a shallow filling. Otherwise, there aren't any fillings on that upper half.

I will happily go back on antibiotics if that might help clear up the infection I guess my worry is just the thought of it spreading to other teeth. But if they are seemingly healthy teeth (as mine are), can an infection spread up through the jaw bone and down into a tooth with no opening (crack, fracture, etc)? And what would be the diagnosis/treatment for this?

The other thing I've read a little about is jaw cavitation, osteonecrosis and the concern over whether the periodontal ligament was removed with the extraction? Can you shed any light on this and whether or not I should be concerned?

Thanks again for your help!
