Sometimes, even after a root canal, lingering pain or infection can indicate the need for further care. However, if your tooth begins to ache again after a root canal, it doesn’t mean all hope is lost. Root canal retreatments give patients a second chance to save their natural teeth, restore comfort, and address unresolved or new infections.


Root canal retreatment is a highly effective solution when previous treatments fail to completely resolve an infection or other complications. At Liv Endodontics Summit, NJ, we use advanced techniques and technology to ensure the process is effective and as comfortable as possible. We’re an excellent choice if you want to give your tooth its best chance to stick with your smile for a lifetime.

What Is a Root Canal Retreatment?

Essentially, a root canal retreatment in Summit, NJ is similar to a typical root canal. However, the retreatment requires an endodontist to examine an already treated area to remove the old filling material. Then, the root canal is recleaned, re-filled, and closed again. 

Generally, root canal retreatments are necessary when a patient feels pain at the original site. This could indicate infection growing in the roots again, meaning the site may not have been sealed off, cleaned, or filled properly. By ensuring the area is treated properly, you can mitigate the possibility of getting more infections. These infections in the mouth can quickly enter the rest of the body, leading to potential health issues that are much more serious.

Root canal retreatment provides many patients peace of mind, allowing them another chance to save their natural teeth. This helps many patients avoid the costs associated with getting an artificial replacement while also enabling them to keep their natural tooth in their smile.

Signs You May Need a Root Canal Retreatment

Several symptoms may indicate you need to visit an endodontist and get a root canal retreatment, such as:

  • Pain, especially when you’re eating, biting down, or having food that is hot or cold
  • Swelling and inflammation around the treated tooth
  • Tenderness in the area, including possible pimple-like bumps in the gums
  • Increased sensitivity in your tooth, such as to cold, hot, or very sweet foods
  • Darkening and discoloration on the affected tooth
  • Discharge or pus coming from the gums
  • Loosened or more mobile tooth
  • Sinus problems, especially for patients who received a root canal in the upper arch of teeth


If you notice any signs that you think your dental team should see, we encourage you to seek out care as soon as possible. Our endodontists at Liv Endodontics can help assess whether you need a root canal retreatment and will guide you through the entire process. In the case a root canal retreatment is not the best option, we can also walk you through your other choices so you can find one that works well for you.

Benefits and Advantages of Getting a Root Canal Retreatment

Patients who receive a root canal retreatment under the correct circumstances can experience several benefits and improvements to their quality of life. The following are some of the positive aspects associated with root canal retreatment:

  • Pain and discomfort relief
  • Preservation of the natural tooth
  • Maintaining typical function while eating, speaking, and managing other daily tasks
  • Cost-effective solution
  • No food restrictions
  • Avoiding long-term replacement treatments

While getting a root canal retreatment can be helpful, patients should also be made aware of the potential downsides of failing to act. If you don’t get a root canal retreatment when one is necessary, you risk losing your tooth. This may mean having a smile that is not whole, experiencing difficulty while eating and speaking, and difficulty when cleaning your teeth. 

The positive impacts are significant, especially compared to the potential downsides of deprioritizing your dental health.
