Ask Dr. King: What to Know About Endodontic Retreatment

Why Didn’t My Root Canal Work?

There may be a variety of reasons. Some of the most common causes of a failed root canal include:

  • Complex canals may have been missed or were not able to be treated during your initial root canal procedure
  • There was a delay in placing a protective restoration after the original root canal was completed
  • A cracked tooth or broken crown or filling may have caused leakage into the initial root canal
  • New decay on the tooth

Can a Failed Root Canal Be Fixed?

If your tooth becomes infected after a first root canal, there are still options for fixing and saving the tooth. Depending on your unique situation, we may recommend redoing the root canal (endodontic retreatment) or an apicoectomy.

Can Antibiotics Heal an Infected Root Canal?

No. Unfortunately, antibiotics are not capable of eliminating root canal infections. Antibiotics may mask your symptoms for some time but they will not eliminate the infection.

What Happens During a Root Canal Retreatment?

During endodontic retreatment, Dr. King will remove the old root canal filling material and locate any untreated canals. We’ll address the underlying issue by disinfecting and then filling each of the canals in your tooth. Lastly, a temporary filling is placed in the top of the tooth until your dentist can place the final restoration.

If you have a crown on the tooth and it doesn’t need to be replaced, there’s no problem performing the retreatment through a small hole made in the top of the crown.

How Long Does a Retreatment Take?

Just like with a typical root canal treatment, endodontic retreatment can take anywhere from 30-90 minutes to complete. It’s possible that Dr. King may recommend medicating your tooth, in which case your treatment will be completed over two appointments at least one week apart.

If during your retreatment we discover that your canals are uncommonly narrow, curved, or impassable, we may recommend endodontic surgery to address the infection from the root end rather than through the top of the tooth. This may create the need for additional appointments.

How Much Does it Cost to Retreat a Root Canal?

Retreatment is an investment in your health and future. It’s also a more affordable option than the alternative, which is typically an extraction and implant. Our front office team will ensure you understand the cost associated with your treatment. We’re happy to work with your insurance company to maximize your benefits and make this process as seamless as possible. Additionally, we offer no-interest financing options through CareCredit.

Do You Provide Sedation During Retreatment?

Yes. We offer several sedation options to reduce any anxiety and improve your root canal experience. These options include nitrous oxide and oral anti-anxiety medications.

Also known as laughing gas, nitrous oxide helps you relax while allowing you to remain fully conscious and able to interact with our team. We use a comfortable breathing mask, allowing you to breathe in the nitrous oxide throughout treatment. Once we remove the mask the effects will wear off in minutes.

We also offer oral anxiolytics, or anti-anxiety, medications. Typically, these come in the form of a pill or tablet and are taken prior to treatment with us.

Dr. King will discuss your options with you and help you decide which option may be best suited for you and your anxiety.
