LRoot Canal work, commonly known as "killing the nerve" is a treatment which is carried out in the interior of the tooth or the dental pulp. This part of the tooth has various functions, one of which is to supply water, fundamental so the teeth don't break.
Root canal work has to be done when the destruction caused by tooth decay affects the internal material of the tooth and it isn't possible to do a filling or artificial reconstruction of the tooth as it would become inflamed and cause great pain. With root canal work the damaged tooth pulp is eliminated and the tooth can be reconstructed, which means that it doesn't have to be extracted. In this way, other, more expensive treatments can be avoided that require a still more complex operation, such as implants.
With current anaesthetic techniques root canal work can be performed without pain, although it a laborious and very complex treatment as the dentist has to perform a series of manoeuvres in an area which is difficult to reach, in a very reduced space and with limited vision. To make up for these spatial limitations, the dentist is guided by the x-rays which are taken regularly throughout the process. The treatment is carried out with fine needles which clean the interior of the tooth that is then sealed with pins made of a special material.
Once the treatment is finished, the tooth that has had the root canal work will be left without blood vessels and will lose the supply of water, which makes it necessary to reconstruct the tooth covering it with a porcelain crown, to preserve the tooth and guarantee its duration.
