RCT Retreatment in Houston, TX

RCT Retreatment in Houston, TX

RCT retreatment, or root canal retreatment, is a procedure we perform at A+ Dental Specialists when a tooth that has previously undergone root canal treatment has developed new problems or complications. Root canal treatment (RCT) is a dental procedure used to treat an infected or damaged tooth by removing the infected pulp and filling the root canals with dental material.

Reasons for RCT Retreatment

Complicated Root Canal Anatomy 

Teeth can have complex root canal systems with variations in the canals' number, size, and shape. If the dentist misses any of these canals during the initial treatment, the tooth may require retreatment. 

Recurrent Decay 

If new decay develops around or underneath a tooth that has undergone RCT, it can cause reinfection and the need for retreatment. 

Cracked or Fractured Tooth 

A tooth treated with RCT can become cracked or fractured over time, allowing bacteria to re-enter the root canal system and cause infection. 

Persistent Symptoms 

If a tooth continues to exhibit symptoms such as pain, swelling, or sensitivity even after the completion of RCT, retreatment may be necessary to address the underlying cause. 

The Process of RCT Retreatment 

The dentist will examine the tooth and review your symptoms and history. X-rays or other imaging may be taken to assess the tooth's condition. Local anesthesia will be administered to numb the area around the tooth, ensuring your comfort during the procedure.

The dentist will then create an access cavity by removing any existing fillings or restorations to gain access to the root canals. The dentist will remove the existing filling material and carefully clean and disinfect the root canals using special instruments and irrigation solutions. 

In some cases, the canals may require reshaping to ensure thorough cleaning and removal of any remaining infected tissue. After cleaning and shaping them, the dentist will fill them with a biocompatible material called gutta-percha and a sealer to prevent reinfection. Once the canals are filled, the access cavity will be restored with a temporary or permanent filling.

A dental crown may sometimes be necessary to strengthen and protect the tooth. After the retreatment, you will likely be prescribed antibiotics or other medications to promote healing. You may also need to schedule a follow-up visit to monitor the tooth's progress. 

It's important to note that not all teeth that have previously undergone RCT will require retreatment. The initial treatment is often successful, and the tooth remains healthy for a lifetime.
