Many people may not be very familiar with secondary root canal treatment. Today, let me explain some related issues and introduce the doctors at Vickong Dental in Zhuhai who specialize in this procedure.
Indications for Secondary Root Canal Treatment
Secondary root canal treatment is usually required when apical periodontitis persists after the first treatment, reinfection occurs inside the root canal, or the previous root canal filling is incomplete. For example, if post-treatment X-rays show persistent dark shadows in the periapical area due to unresolved periapical lesions, the patient may be indicated for secondary root canal treatment.

Advantages of Secondary Root Canal Treatment
Eliminates Inflammatory Lesions:If chronic inflammation around the root tip is left untreated, it may act as a trigger for systemic diseases such as cardiovascular disease, diabetes, and may even lead to serious local conditions like jaw osteomyelitis. Secondary root canal treatment helps remove the source of infection and safeguards overall health.
Cost-Effective Option:Compared to tooth extraction followed by dental implants, secondary root canal treatment can be more cost-effective in certain cases. Dental implants tend to be expensive and require a longer treatment period. If secondary root canal treatment is successful, it can restore tooth function quickly, save on costs, and minimize patient discomfort and inconvenience.
Pricing for Secondary Root Canal Treatment in Macau and Zhuhai
In Macau, dentists typically quote based on the complexity of the root canals, the difficulty of the procedure, and the estimated number of treatment sessions. Generally, the cost ranges from MOP 15,000 to MOP 35,000.
In comparison, Vickong Dental in Zhuhai offers more affordable pricing:
Front tooth secondary root canal: RMB 1,200
Molar secondary root canal: RMB 2,250
The package includes a free consultation and a detailed treatment plan.
Recommended Dentists for Secondary Root Canal Treatment
Secondary root canal treatment is generally more challenging and complex than primary treatment. After a failed first attempt, residual infections, calcifications, fractured instruments, and altered canal structures can make identifying the root canal pathways much more difficult. This greatly increases the complexity of debridement and refilling. Moreover, delayed treatment may cause the inflammation around the root tip to worsen, even resulting in bone loss, which requires the dentist to have excellent microsurgical skills and clinical judgement.
At Vickong Dental, Dr. Leung Chi Ying, who holds a Master’s Degree in Dentistry from West China School of Stomatology, Sichuan University, specializes in complex root canal retreatments. Many patients who previously suffered from toothaches due to failed initial treatments have successfully preserved their teeth and regained normal chewing function under Dr. Leung's care. If you have dental issues, you may consider consulting Vickong Dental and let Dr. Leung design a personalized treatment plan to help you resolve your dental troubles with ease.
