If a dental nerve has died because of a deep caries or an injury, the remainingcanal is closed with a root filling. On this occasion, aim is to avoid a penetration of bacteria by the highway root canal in the surrounding bone.
Unfortunately, this root treatment must be looked by dead teeth as acompromise and can be always only one attempt to hold the tooth further more usable. The root canal system is often branched out so strongly that one cannot succeed in holding this canalsystem on a continuing basis aseptic. Nevertheless, in most cases the bodycan handle with it, which is why the treatment of dead teeth is for many decades a firm component of the dentalmedicine. Not every root-treated tooth is immediately a problem what must beremoved.
However, germs and dead fabric canstay behind in such a tooth or immigrateby leaking fillings new germs. On this occasion, originates sulphur hydrogen (Methylmercaptan, Thioether) which causes an inflammation charm and towhich the body immunological as well as toxicologisch can react.
In the biological consideration is the best result of treatment what can be reached, that which is so low that the dead tooth is tolerated by the organism further more.
Hence, it must be met in the agreement between dentist and patient the consideration whether a root treatment should be carried out and how high the biological risks linked with it are to be estimated. However, a forecast is difficult because of many not foreseeable dimensions of influence toput.
For patients ill hard and chronically the possibility of an influencing control of aroot-treated tooth on the illness should be only already a reason enough to separate from him.
