Root canals are a common dental procedure to save a tooth that is infected or badly decayed. However, like any medical treatment, there is a chance of root canal failure. In this article, we will explore the reasons behind root canal failure, how it can be diagnosed or treated, and the steps to take if you suspect your root canal has failed.
Understanding the Problem
When a root canal treatment fails, it means that the tooth is still causing pain or showing signs of infection. This can happen shortly after the initial treatment or even years later. Some patients may experience persistent pain, swelling, or sensitivity to hot or cold temperatures. These are common failed root canal symptoms that indicate a potential issue.
What Causes It
There are several reasons why a root canal may fail. In some cases, the initial treatment may not have effectively cleaned the infected area inside the tooth. Bacteria can remain, leading to reinfection. A new fracture in the tooth or a poorly placed crown can also cause failure. Additionally, undetected canals or complex canal systems may have been missed during the first treatment.
How It’s Diagnosed or Treated
If you are experiencing symptoms of a failed root canal, your dentist will evaluate your tooth using X-rays and other diagnostic tools. They will look for signs of infection, bone loss, or other issues that may be causing the symptoms. To confirm the diagnosis, they may perform tests to check the tooth’s responsiveness.
Root canal retreatment is often the next step to address a failed root canal. During this procedure, the filling material is removed, and the canals are cleaned and reshaped. The tooth is then filled with new material to prevent further infection. In some cases, endodontic surgery may be necessary to save the tooth.
What to Do Next
If you suspect that your root canal has failed, it is crucial to seek professional help promptly. Delaying treatment can lead to further complications and may result in the loss of the tooth. Contact your dentist to schedule an appointment for a thorough evaluation and appropriate treatment.
It’s important to note that the success rates of root canal retreatment are generally high. With advancements in technology and techniques, endodontists can often save a tooth that has experienced a failed root canal. Following the retreatment, proper oral hygiene practices and regular dental check-ups are essential to maintain the health of the treated tooth.
