2 Root Canals on Same Tooth Still Pain: Seeking Solutions for Relief

April 1, 2024


Have you recently undergone not one, but two root canals on the same tooth, yet continue to experience discomfort? Dealing with persistent pain can be frustrating and confusing, especially after going through the process of root canal treatment. This blog unravels the mystery behind why you may still be feeling pain despite having had two root canals on the same tooth. Let’s delve deeper into this dental dilemma.

What is a Root Canal?

A root canal is an oral care process designed to save a tooth that has been severely damaged by decay, disease, or injury. During the method, the dentist removes the infected or inflamed pulp from inside the tooth, cleans and disinfects the inner chambers, and then fills and seals the space to avoid further infection.

Understanding Root Canal Treatment

Root canal treatment in Houston is a common dental procedure aimed at saving a severely infected or damaged tooth. During a root canal, the infected pulp lying inside the tooth is taken out, and the root canal is cleaned, disinfected, and then sealed to prevent further infection. While this treatment is typically successful in alleviating pain and restoring the health of the tooth, there are instances where patients may continue to experience discomfort even after undergoing a root canal.

Why Do You Still Feel Pain After 2 Root Canals?

  1. Incomplete Removal of Infected Tissue: If not all of the infected tissue is removed during the root canal procedure, it can lead to persistent pain and discomfort.
  2. Undetected Cracks or Fractures: Cracks or fractures in the tooth that were not identified or addressed during the root canal can also cause ongoing pain.
  3. Reinfection of the Tooth: In some cases, the tooth may become reinfected due to a new infection entering the root canal system, causing pain to persist.
  4. Nerve Damage: Damage to the nerve during the root canal procedure or inflammation of the surrounding tissues can result in lingering pain.
  5. Failed Seal: Over time, the sealant used to fill the tooth after a root canal can break down, allowing bacteria to re-enter the tooth and cause infection.
  6. Recurrent Decay: Decay can develop under or around the restoration, compromising the tooth’s integrity and causing pain.

What Can Be Done About Persistent Pain?

If you are still experiencing pain after having two root canals on the same tooth, it is vital to consult with your dentist to determine the underlying cause of the discomfort. Your dentist may recommend the following steps to address the issue:

  • Diagnostic Imaging: X-rays or other imaging techniques can help find out any underlying issues such as cracks, fractures, or infection.
  • Root Canal Retreatment: In cases where the previous root canals were unsuccessful, retreatment may be necessary to address the persistent pain.
  • Apicoectomy: If the root of the tooth is still causing pain, an apicoectomy, which involves the removal of the tooth’s root tip, may be recommended.
  • Tooth Extraction: In extremee cases where the tooth cannot be saved, extraction may be necessary to relieve pain and prevent further complications.


  1. Is it common to have pain after a root canal treatment?

Though some discomfort is normal immediately after the procedure, but persistent or increasing pain warrants a follow-up with your dentist.

  1. Can a tooth be treated more than once with a root canal?

Yes, a tooth can undergo root canal retreatment if necessary, depending on the condition of the tooth and the complexity of its root system.

  1. What are the signs that a root canal has failed?

Signs include persistent pain, swelling, and sensitivity to heat or cold, indicating that the tooth may still be infected.
