Informed Consent for Root Canal (Endodontic) Therapy

Patient and Treatment Information

Nature and Purpose of the Procedure

Root canal therapy (endodontic treatment) is performed to save a diseased, infected, or severely decayed tooth and relieve pain. The treatment involves removing the damaged or dead dental pulp (the nerve, blood vessels, and connective tissue inside the tooth). Under local anesthesia, a dental dam is placed to isolate the tooth and keep it sterile. The dentist drills an access opening through the crown of the tooth into the pulp chamber. The pulp is removed from the chamber and root canals using small instruments (files) and chemical disinfectants. The canals are shaped, cleaned, and then filled and sealed with a rubber-like material called gutta-percha. A temporary filling is placed in the access cavity. The procedure typically requires 1 or 2 appointments, taking 45 to 90 minutes per visit.

Material Risks and Potential Complications

Tooth discoloration: the tooth crown darkening or turning grey or yellow over time, which may require internal bleaching or cosmetic restoration (crown/veneer).
Infection recurrence: persistent or recurrent infection at the root tip (apical periodontitis) due to complex, hidden, or calcified canal pathways that could not be fully cleaned, which may require endodontic retreatment or apical surgery (apicoectomy).
Tooth fracture: the tooth becoming brittle and prone to cracking or fracturing after pulp removal, particularly if a final protective crown is not placed in a timely manner.
Need for extraction: vertical root fractures occurring during or after treatment, or severe infection that does not resolve, making the tooth unsavable and requiring extraction.
Instrument separation: a fine file breaking or separating inside a narrow root canal, which may be left in place and sealed if it cannot be retrieved, requiring regular monitoring.
Perforation: accidental puncture of the root wall or floor of the pulp chamber during drilling, which requires specialized repair materials or may compromise the tooth's long-term survival.

Reasonable Alternatives

Tooth extraction: complete removal of the diseased tooth, followed by replacement options such as a dental implant, bridge, or partial denture to prevent adjacent teeth shifting.
No treatment: delaying care, which will lead to worsening pain, dental abscess, bone loss around the root, and spread of infection into the facial spaces.

Critical Post-Endodontic Restoration Requirement

A root canal treated tooth is structurally weakened and highly vulnerable to fracture under normal chewing forces. The placement of a permanent restoration (typically a core build-up and a full-coverage crown) is critical to protect the tooth and seal it from oral bacteria. Failure to place the permanent restoration within 4 to 6 weeks following root canal completion increases the risk of tooth fracture or bacterial leakage, which can lead to treatment failure and require tooth extraction.

Questions and Understanding Confirmation

I confirm that I have had the opportunity to read this consent form and discuss it with my dentist. I understand that root canal therapy is not guaranteed to save the tooth, and that a permanent crown is required afterward. I believe I am making an informed and voluntary decision.
