Re-Root Canal Treatment (RCT Retreatment)
A root canal-treated tooth can sometimes develop persistent pain, sensitivity, swelling, or infection. In such cases, Re-Root Canal Treatment (RCT Retreatment) may be recommended to address problems that were not fully resolved during the initial procedure.
When Is RCT Retreatment Needed?
Root canal retreatment may be considered when infection returns or continues because of incomplete cleaning, untreated canals, leakage, or problems with an existing dental restoration. Common symptoms can include tooth pain while chewing, recurring swelling, tenderness, or sensitivity around the treated tooth.
What Does the Treatment Involve?
The dentist carefully examines the affected tooth and may recommend dental X-rays or other imaging. During retreatment, the previous filling material is removed, the root canals are thoroughly cleaned and disinfected, and the canals are sealed again. A suitable restoration or dental crown may then be recommended to protect the tooth.
