Reasons Why a Root Canal Treatment Might Fail

Millions of people globally have benefited from root canal treatment and secured their teeth in crisis. It is a vital dental procedure that halts advanced tooth decay from further infection and destruction. You can extend the tooth’s life for decades by undergoing a root canal treatment. Although the success rate of a root canal is high, there is still a chance that the treated tooth might become re-infected.

The feeling of discomfort is normal when you are recovering, but how would you determine if there is anything you should be concerned about? Here, we will discuss the possible reasons for the failure of a root canal treatment.

Common Symptoms for a Failed Root Canal Treatment

Even if the root canal treatment produces satisfactory results, the common aftereffects that a patient endures include the feeling of tenderness or irritation in the surrounding areas of the tooth and tissues. However, in a failed root canal treatment, an individual will display signs like:

  • Severe pain while chewing or biting
  • Swelling or soreness in treated tooth and neighboring areas
  • Lose tooth
  • A blister or bump in surrounding areas of the treated tooth

Reasons for an Unsuccessful Root Canal Treatment

In most cases, this endodontic treatment proves to be effective and provides longevity to the tooth. Unfortunately, few cases reflect its rate of failure as well. The most prevalent causes of unsuccessful root canal treatment include:

  • Coronal Leakage

When the substance of the crown is not of high-quality, it allows the bacteria to seep back into the teeth. Moreover, a dislodged dental filing is also alarming, as your tooth is providing a clear way for the bacteria to re-infiltrate into the tooth. It indicates that the dental crown serves as the most significant part that prevents bacterial leakage; therefore, a high-quality crown curtails the risks of root canal failure.

  • The Intricacy of Tooth Roots

In some cases, root canals are treated incompletely because of the complexity of the tooth roots and is explained as a justification for a failed root canal treatment. It happens because, the roots, in few teeth, are hidden to the extent that they are left undiscovered during the root canal, and are not likely to show up on conventional angles in x-rays. Thereby, left untreated roots trigger pain even after the treatment.

  • Crack or Fracture in Tooth

The age of the patient’s tooth plays a substantial part when a root canal treatment is being performed, as the therapy makes older teeth vulnerable to fractures or hairline cracks. Consequently, the cracked tooth is at a greater risk of catching infection with the re-penetration of bacteria into the tooth.

  • Perforation in Tooth Root

A root canal is performed in small quarters, which point towards the probability of accidental perforation. While cleaning the tooth roots, the untreated, unnoticed, or unsealed punctures permit the bacteria to re-enter and form decay. The perforation is another prime aspect that determines why a root canal treatment can fail.

If you feel severe pain and discomfort in your root canal-treated tooth for longer periods, you must consult your dentist on an immediate basis. Delays in re-retreating the failed root canal will lead to further deterioration in the jawbone and tooth.
