Reinfection After a Root Canal: What You Need to Know
Feb 10, 2025
Getting a root canal is often a huge relief! It saves your tooth and ends your pain. But what happens when that familiar ache or discomfort begins again?
At LLanos Dental Group, experienced dentist Laura Llanos, DMD, knows that while root canals are highly effective, reinfection sometimes occurs. Understanding why reinfection happens and how it can be treated is key to resolving the issue and safeguarding your smile.
Here’s everything you need to know about managing reinfection after a root canal.
While a root canal removes bacteria and infected tissues from inside your tooth, certain factors can lead to reinfection. Here are just a few potential causes you should keep in mind — identifying these problems can help you get the timely treatment you need:
If all the bacteria or infected tissue isn’t fully removed during your procedure, the infection can resurface.
Tiny cracks can form over time, allowing bacteria to enter and cause reinfection.
If your filling or crown isn’t properly sealed, bacteria can seep in and reinfect your tooth.
A cavity near your treated tooth can introduce bacteria and compromise the initial work.
It’s important to recognize the symptoms of reinfection so you can act quickly. If you notice any of the following symptoms, don’t ignore them — call us immediately.
The good news is that reinfection after a root canal can usually be treated. Dr. Llanos will recommend the best course of action based on the severity of your infection and the condition of your tooth. Here’s how our team might address it:
Your tooth is reopened, cleaned again, and refilled to remove lingering bacteria and seal the canals.
If retreatment isn’t an option, an apicoectomy may be performed. During the procedure, the tip of the root is removed, and the area is sealed to prevent further infection.
In severe cases where your tooth cannot be saved, extraction may be necessary. This is followed by a replacement option like an implant or bridge.
Reinfection after a root canal can be frustrating, but don’t worry — it’s treatable! By understanding the causes, recognizing your symptoms, and seeking timely care, you can address the issue and preserve your smile.
