hi blicero: here is some info from the DAMS news letter on root canals : you have a couple of options a safer root canal treatment through a holistic dentist oxygen zone injections to sterilize the dead tooth then they use a less toxic root canal filling material called endocal-10 this material is thought to greatly expand into detin tubules,sealing them and killing off any bacteria that is encountered the other option is safe extraction ,as for my own experience I 've only had one root canal and the dentist that did the work did not do the root canal correctly and had problems from the start and had to have it extracted 14 months later , if she does get it extracted there is always the option of a dental implant or bridge work down the road to fill the empty space of the missing tooth
