Did you recently have a root canal performed on your tooth, thinking it would last a lifetime but re-infected in days? Such failure can be concerning, but your teeth have a complex web of canals, so give your dentist the benefit of the doubt. For example, lower incisors with a single canal can possess two, a hidden second canal perhaps your dentist could not see.

Root Canal Failure Symptoms

The symptoms of a failed root canal can be:

  • Sharp pain while chewing down
  • A blister on the jaw
  • Tooth discoloration
  • Swelling in the gum tissue at the root canal site
  • Pain in the affected tooth
  • Fluid-filled abscess formation around the site of the root canal
  • Swelling in the face or lymph nodes

It is advised that you immediately seek medical attention. Dr. Sea at Dynamic Dental Solutions is a qualified endodontist you need for this problem.

Possible Causes of a Failed Root Canal

A failed root canal means that your treatment failed to address the underlying issue or infection in the tooth. This can be due to:

  • Incomplete Cleaning and Shaping: If the dentist fails to thoroughly clean and shape the root canals, bacteria can stay in the tooth, resulting in recurring infection.
  • Missed Canals: Some teeth have complicated root canal systems, and if a dentist mistakenly skips one or more canals during the treatment, it can lead to an incomplete procedure and root canal disaster.
  • Inadequate Sealing of the Canal: Proper sealing of the cleaned root canals is crucial to prevent bacteria from re-entering. Infection can persist if the seal is not tight or there are gaps.
  • Fractured Tooth: A cracked tooth can let bacteria re-enter the root canal system. The crack can be hard to detect in certain cases due to low visibility.
  • Persistent infection: If the tooth has a rigorous infection that extends beyond the root canal system, the root canal cannot properly kill all bacteria.
  • Recontamination: Bacteria can re-enter the treated tooth if a temporary or permanent restoration is not placed immediately after the root canal. Delay in fixing a crown or filling can leave the tooth vulnerable to contamination.
  • Coronal leakage: If there is leakage around the restoration, bacteria from the oral cavity can seep into the treated tooth, causing reinfection.
  • Poor oral hygiene: Improper oral hygiene habits can lead to the recurrence of infection. Patients must maintain proper oral health to avoid it.
  • Systemic health issues: Systemic health problems, like poor immune function, can negatively influence the body’s ability to battle infection, failing a root canal.
  • Undetected canal anomalies: Some teeth can have anatomical variations, like excessive canals or different configurations, which can be hard to identify and treat. Failure to tackle these anomalies can cause treatment failure.

Root Canal Failure Treatment

Remember that although root canal treatments have the highest success rate, no dental treatments come with a 100% guarantee. Retreatment or alternative procedures can be considered in case of a failed root canal. An apicoectomy or tooth extraction can resolve the issue.
