Endodontics consists of cleaning the pulpar chamber and the root conducts and sealing it with plastic material in the form of orange sticks called gutta-percha. This technique enables us to hermetically seal the conducts throughout their length in order to avoid any future infection.

The conducts are cleaned with the very fine files (there is a conduct for each root of the tooth) to clean its walls well. We have flexible files to minimise their breakage in the conduct.

We progressively increase the thickness of the files until the conduct is clean and ready to be filled with the gutta-percha in plastic state to completely adapt to the morphology of the root conduct.

This is a treatment that requires great precision and the help of sophisticated methods to achieve it, such as x-rays and apex localisers, to ensure that the gutta-percha gets right to the tip of the root and seals its entrance.

This makes it lose water and means that it is more fragile than when it was a vital tooth, so very often we have to protect it with a sleeve to avoid crown fractures.

Sometimes it will be necessary to strengthen it with a bolt or screw that we insert in one of the treated conducts (generally the widest) on which tooth decay caused a large loss of enamel and dentin.

We will also see that these endodontic-treated teeth darken more than the others in the long-term, and become more fragile.
