What Happens If a Root Canal Fails?


Posted on 2/2/2024 by Florida Smiles Dental
Root canal image. Following a successful root canal procedure, the tooth will settle and the pain will gradually go away. However, if you consistently feel the pain after treatment or it returns after you have recovered, then the root canal procedure has failed. In that case, it needs to be redone. Here are some common causes of root canal failure.

Causes of Root Canal Failure


A root canal failure occurs mainly because of the bacteria that remain present in the root canal. Such bacteria find a way of re-entering the tooth after treatment. There are several other causes of root canal failure. For instance, it could be due to a dislodged or leaking dental filling. This can lead to the entry of bacteria into the tooth. Dental crowns can lead to leakages that result in root canal failure. Similarly, a dislodged dental filling can leave spaces in your tooth, making it vulnerable to bacteria attack. When this happens, you will start experiencing symptoms of decay like toothaches and sensitivity.

Another common cause of root canal failure is a fractured or cracked tooth. A cracked tooth means its enamel is damaged. The enamel is a thick layer that protects your tooth from bacterial intrusion. When it is damaged, your tooth is exposed to bacteria and other pathogens. You are more likely to experience root canal failure with a fractured or cracked tooth.

Be On the Lookout


Cavities or dental decay can also cause root canal failure. These conditions affect the health of your teeth, canceling the gains made by a root canal procedure. Tooth decay can occur, especially if there are leakages or dislodged dental fillings. Keep in mind that other conditions like periodontal ligament can also cause root canal failure. While it is highly likely that the root canal procedure will be successful, you should put measures in place to ensure that remains the case. For instance, you should practice good oral hygiene and avoid interfering with the wound.

You should be on the lookout for signs of these dental issues and get them fixed immediately. Get in touch with us for more information on what happens when a root canal fails and how to rectify such anomalies.
