A dead tooth should be root-treated, or it develops adverse long-term effects on the entire body (tooth focus or focus).

We process all canals with break-resistant hand files, not with mechanical systems. We do without unbiological disinfection procedures and hygiene achieve with the Nd-YAG laser (www.dekalaser.de) and the 3-D hot-pressing-filling (thermoplastic root filling after Prof. Schilder, Boston), the best current technology.

Proven and new materials often allow the rehabilitation of apparently hopeless teeth. In severely ill people, especially cancer patients, in very old people and poor prevention willingness root treatments, however, should be avoided.
