When a previous root canal does not heal as expected, retreatment can resolve the infection and preserve your tooth. At Drs. Nicolas & Asp Centers, we use advanced imaging, magnification, and precise techniques to manage even complex retreatment cases with care and predictability.
Root canal retreatment is performed when a tooth that has already had a root canal develops persistent infection or symptoms.
The tooth is reopened, the previous filling is removed, and the canals are cleaned and sealed again — giving the tooth another opportunity to heal and function normally.
Our specialist endodontists across Jumeirah, Dubai Marina, The Springs, and Uptown Mirdif provide root canal retreatment—an advanced procedure to address persistent infection, preserve your natural tooth, and restore long-term oral health.
Even well-performed treatments can fail over time. Our focus is always to identify the exact cause before retreatment. Common reasons include:
Some patients have no symptoms — which is why regular check-ups are important.
We assess the tooth and, when needed, use CBCT imaging to understand the full root structure.
The original root canal material is carefully removed to access the canals.
The canals are cleaned, disinfected, and refined. Hidden canals and complex anatomy are addressed using an endodontic microscope.
The canals are sealed again, and the tooth is restored — usually with a crown for long-term protection.
Treatment is performed under local anaesthesia, so the procedure itself is comfortable.Afterwards, mild soreness is possible for a few days, but this is usually manageable with simple medication and settles quickly.
Root canal retreatment is a predictable procedure when carefully planned.Success depends on:
With the right approach, many retreated teeth remain functional for years.
Whenever possible, saving your natural tooth is the preferred option.
Retreatment helps you:
If the tooth cannot be saved and has to be extracted, we will guide you through suitable replacement options such as dental implants or bridges.
Root canal retreatment is performed by dental specialists with advanced training in endodontics, experienced in managing complex and previously treated teeth with precision and care.
Accurate diagnosis is essential — especially for retreatment cases. CBCT imaging allows us to identify hidden canals, complex anatomy, and areas of infection in detail.
Treatment is performed using a high-power dental microscope, which is standard in modern endodontic care. This level of magnification allows precise identification of fine canal structures, missed anatomy, and previous treatment challenges — improving accuracy and outcomes.
From diagnosis to final restoration, your treatment is fully coordinated — ensuring continuity and quality at every stage.
Over 30 years of experience caring for patients across Dubai, with a strong reputation for specialist-led, patient-focused care.
It has a high success rate, but outcomes depend on the specific condition of the tooth.
Each visit typically lasts about 60 to 90 minutes, depending on the complexity of the tooth and the treatment required. Some cases may be completed in a single visit, while others may need more than one visit to ensure the infection is fully managed.
Surgical endodontic treatment (apicoectomy) may be recommended if retreatment is not sufficient to resolve the infection. If the tooth cannot be saved and requires extraction, suitable replacement options — such as a dental implant or bridge — will be discussed to restore function and protect your oral health.
In many cases, yes — a new crown helps protect the tooth after retreatment and reduces the risk of infection coming back.
Research from the American Association of Endodontists shows that properly sealing and protecting the tooth after treatment is important for long-term success. A crown also strengthens the tooth, so you can bite and chew comfortably again.
The procedure is performed under local anaesthesia, and most patients find it comfortable. Mild soreness afterwards is normal and temporary.
Many dental insurance plans provide partial coverage for root canal retreatment. Coverage depends on your specific policy, including limits, exclusions, and pre-approval requirements. Our team will guide you through your benefits, assist with pre-approvals, and support you throughout the process.
If you are experiencing symptoms after a previous root canal, early assessment can help save your tooth.
