A previously root-treated tooth sometimes needs further care. Retreatment aims to address a problem inside the canals when preserving the tooth remains reasonable.

Reassess the whole tooth

The endodontist considers the previous treatment, restoration and remaining tooth structure. Persistent infection or a new problem may prompt reassessment. Pain alone does not identify which procedure is needed.

How retreatment differs

The tooth is reopened so previous canal materials can be removed and the canals reassessed, cleaned and sealed again. Access through or removal of an existing restoration may be necessary.

Compare the complete options

Ask why nonsurgical retreatment, root-end surgery or extraction is being discussed in your case. Have the estimate identify the endodontic work and the final restoration, including who coordinates follow-up.

Costs and coverage in Canada

Your cost depends on the proposed plan and your situation. Request a written estimate showing each stage, laboratory fees and follow-up. CDCP coverage depends on program rules, eligibility and the exact service. Confirm your share before treatment.
