The interior chamber of a tooth, known as the root canal, is filled with loose tissue (pulp) and a dense network of blood, lymphatic, and nerve arteries. Its intricacy can range from 1 to 4 distinct or interconnected canals, depending on the type of tooth.
Contrary to popular assumption, discomfort is not usually a sign of a canal injury. There is very little pain or discomfort in more than 90% of situations involving damaging activities in the pulp chamber. When a patient visits the dentist for a caries problem, video diagnostics are frequently used to determine whether root canal therapy is required.
Based on unique considerations such as tooth anatomy, the degree of damage, and the patient’s age, the dentist chooses the best endodontic treatment strategy.
The tight gap that restricts full access and makes floor examination challenging makes treating the canal in anterior teeth difficult. The existence of a projection (“shoulder”) adds to the difficulty by preventing the endodontic post from entering directly. As a result, access is gained from the crown’s back.
When the nerve is irritated, wisdom teeth, which are not frequently utilized for chewing, are typically not filled. Instead, the root canal is removed.

Therapy is administered to young patients with primary teeth as the root system is developing. Iodoform and zinc oxide eugenol are two examples of specialized pastes that are used to protect the developing permanent teeth. These pastes are easily absorbed by the body and have no harmful effects.
The steps in dental canal therapy often include cleaning out cavities, removing pulp, measuring the length of the root canals, contouring the canals, and then filling them.
