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.

  • As the tooth is discolored and it is infected for long the infection has become chronic. In such cases single sitting root canal is not effective. Moreso ever if resorption of the apex has taken place then apicectomy has to be done. In that the apical part of the root is cut . whether the tooth can be saved or not depends upon the clinical examination and radiographic evaluation. If the tooth has sufficient bone support then it is practical to save the tooth . If the dentist thinks that it can not be saved then it should be pulled out and you can go for dental implant or bridge in such cases. For more info on apicectomy you can visit the following
