The process usually takes 60–90 minutes and may span 1–3 visits, depending on infection severity. Local anesthesia is administered first to ensure complete comfort throughout the procedure.
X-rays confirm the issue. A rubber dam isolates the tooth, and the dentist drills an access hole through the crown to reach the pulp chamber and root canals.
Infected or dead pulp tissue is removed using specialized files. If there's an abscess, it is carefully drained at this stage.
Canals are cleaned, disinfected with sodium hypochlorite, and shaped using files to remove debris and bacteria. Irrigation and medicaments may be used in multi-visit cases.
Canals are dried and filled with biocompatible gutta-percha and sealer. A temporary filling seals the access hole between visits.
At follow-up, the temporary filling is replaced with a permanent one or crown to strengthen and protect the tooth long-term.
