Number 25 has been discolored for two decades. Three years ago, a dentist suggested a root canal and I ignored it. In August a draining sore appeared between 21 and 22. A DDS prescribed Clendamycyin for 10 days and said it could probably be attributed to number 25. The sore went away. In September a similar sore appeared between 26 and 27. Both sores appeared between the lower incisors and canines. I went to a Periodontist who put me on Amoxicillin and referred me to a root canal specialist. The sore reappeared within days of the end of the amoxicillin.
The specialist drilled and treated 25 and added a temporary plug and said we would wait one month to see how the tooth responded. The sore did not drain for three days - - the longest it had remained dry in weeks. Late on the fourth day, the pus started draining again.
I guess this is a paradigm of why they used to pack root canals with arsenic; it was a good antibiotic. This root canal specialist says that other than the bleach and tetracycline that they clean the canal with, he will not be adding any long-term antibiotic to the tooth.
I am reluctant to keep this tooth unless I see the infection go away. I understand that there are doxycycline products that can be buried under the gum to provide long-term protection against infection. Please also note that I have proven extra-suseptable to obligate intracellular parasites in the past in which doxycyline has proven viable. The fact that tetracycline seems to have ameliorated the infection for a few days gives me hope that a long-term implant may save the tooth.
Any suggestions from the dental community would be appreciated.
