I am quite happy that I belong to the persons who had to google endodontic therapy. I feel sorry for every person who knows details about that because of their own experience. Every tooth contains nerves and blood vessels. They are coming through the root and are filling the pulp (the “hole” below the hard surface of the crown). Tooth damage (e.g. by cavity) can damage of the tooth or bacterial infection can lead to an infection of the nerves in the then unprotected pulp. In order to protect the tooth, the dentist removes all nerve tissue and the blood vessels (and other organic material). Desinfection secures that no bacterial infection will occur (again) in this tooth and then the holed tooth is filled with some material and protected by a crown. Herbert Schilder published a paper in 2006, in which he describes the problem of the three dimensional filling of the holed tooth. Filling material can be e.g. solid cores of gutta percha or silver which are connected to the tooth by cementing material. The problem is the complete sealing of the whole hole. The solid core needs to be adapted to the hole form and even then it is hard to guarantee that besides the main root canals all lateral accessory canals are sealed and protected from infection. Therefore, in addition to a solid gutta percha core, gutta percha (according to wikipedia: “a natural polymer prepared from latex from the percha (Palaquium gutta) tree”) can heated up. While gutta percha is heated up its get softer and helps to fill the gap between the the solid core and the tooth and so reduces the amount of cement which is needed. Lets hope we will never need that knowledge. "Filling root canals in three dimensions."
