In the vast majority of cases, endodontic treatment is performed because of extensive tooth decay that reaches the nerve and causes severe pain.
In other cases, the treatment is applied to teeth with a chronic pulp condition, that is, teeth in which the nerve has already been lost due to infection (necrosis) but where there is no pain. In these cases, a fistula is sometimes produced, a small lump that can occasionally appear at about 10 mm above the crown of the affected tooth. Blows and gum infections can also lead to the need for endodontic treatment.
This treatment may also be performed if there is a phlegmon, in fact, it’s the ideal treatment for sorting out this problem, as phlegmons are produced by an infectious process in the tissues surrounding the tooth. This can sometimes be caused by a diseased pulp and this treatment eliminates the affected pulp and removes infection from the tooth canals.
Endodontic treatment is the best option as the top priority is to try to save the natural teeth, although if this isn’t possible, the tooth will have to be removed and replaced with a suitable prosthetic.
