Root Canal Retreatment

What is root canal retreatment?

Root canal retreatment is a procedure performed on a tooth that has already received root canal treatment but has developed problems. Sometimes, a tooth that was successfully treated initially can fail months or even years later due to a new infection, incomplete healing, or a new crack that allows bacteria to enter. Retreatment removes the previous filling material, carefully cleans the canals again, and reseals them with fresh material to eliminate the problem.

Our endodontists use advanced imaging and specialized techniques during retreatment to identify issues that may have prevented healing from the initial treatment. By addressing the root cause of the problem, we give your natural tooth the best opportunity to heal and function properly for many more years to come. And if you're unsure whether retreatment is right for you, we're always happy to provide a second opinion and walk you through your options.

Why choose specialist retreatment?

Benefits of root canal retreatment

Save Your Natural Tooth

Gives a previously treated tooth a second opportunity to heal and function, avoiding the need for extraction and replacement.

Eliminate Persistent Pain

Removes the source of discomfort in a tooth that continues to cause problems after initial treatment, restoring your quality of life.

Avoid Tooth Loss

Preserves your natural tooth structure and prevents bone loss that occurs after extraction, maintaining your long-term oral health.

Cost-Effective Solution

Costs significantly less than extracting the tooth and replacing it with an implant or bridge while saving your original tooth.

The Procedure

Our step-by-step
retreatment process

When a tooth needs a second chance, our careful approach identifies the problem and gives your natural tooth the opportunity to heal.

01

Comprehensive Evaluation

We examine your tooth with advanced 3D imaging to identify why the previous treatment may have failed. Understanding the problem guides our retreatment strategy.

02

Access and Removal

We carefully create access to your tooth's interior and remove the previous filling material. This allows us to thoroughly inspect all canals and identify any issues.

03

Thorough Cleaning

We meticulously clean and reshape the root canals using specialized instruments and antimicrobial solutions. This removes any remaining infection or debris from the previous treatment.

04

Disinfection Protocol

We disinfect the canals with powerful antimicrobial agents to ensure all bacteria and infection are eliminated. This step is critical for successful retreatment.

05

Final Sealing

The canals are filled with fresh biocompatible material and sealed to prevent reinfection. This creates a complete seal that allows your tooth to heal.

  • Zeiss Microscopes Operating microscopes provide magnified visualization of your tooth's interior, allowing our endodontists to work with exceptional precision and accuracy.
  • Gentlewave Technology Gentlewave uses fluid dynamics and acoustic waves to gently clean and shape root canals, resulting in more thorough disinfection and faster healing.
  • Digital Radiography Digital X-ray imaging delivers clearer, more detailed images than traditional film while exposing you to significantly lower levels of radiation.

Symptoms & Indications

When retreatment is needed

Returning Pain

Pain that develops in a previously treated tooth may indicate a new infection or incomplete healing requiring professional retreatment.

Swelling or Abscess

Facial swelling or a pimple-like bump on your gums near a treated tooth may signal that the tooth needs retreatment to eliminate infection.

Treatment Failure

If a treated tooth fails to heal properly or develops problems months or years after initial treatment, retreatment offers a solution.

New Decay or Cracks

New cavities or cracks in a previously treated tooth can allow bacteria to reenter the canal system, necessitating retreatment.

Patient Reviews

What our patients say

★★★★★

“Dr Jonsson is the best doctor in the world. I've been to a handful of doctors in my life and never have I met a doctor with such amazing bedside manners and care and patience towards his patients. I went in for an emergency root canal and was crying because I was so nervous. He treated me with such care from the moment he started until he ended. I felt no pain and not even the numbing shot.”

“Starting with the consultation, the staff were all very professional and patient. Dr. Jonsson spent the time to explain everything clearly and really made me feel like I was in good hands. My procedure was quick and painless. Dr. Jonsson made sure that comfort was a top priority and also explained every step of the process as we went. After the procedure, Dr. Jonsson followed up later that day to check on how I was feeling.”

Well they didn't lie. It wasn't even close. It was literally the BEST dental experience of my life. I would highly recommend Dr. Jonsson and his team for any endodontic needs. Best of the best!!”

“Dr. Jonsson took the time to explain every step of the procedure, answered all my questions, and ensured I was comfortable throughout the entire process. What impressed me most was their gentle touch and precise technique — I barely felt a thing! I had minimal discomfort afterward and I love that he followed up with me the same day to see how I was feeling.”

“I came to Saddleback Valley Endodontics with a very complex case involving inflammation and bone loss, and what I experienced was nothing short of miraculous. I never thought I would say this about a root canal, but I almost fell asleep in the chair. There was zero tension and absolutely zero pain. It wasn't general anesthesia — it was simply the result of Dr. Chu's incredible skill and the stress-free environment he creates.”

“I needed a root canal. I was treated by Dr. Wayland Chu and let me tell you He is TRULY AMAZING!!! I did not feel anything and could have fallen asleep there. The most pleasant experience ever in a Dentist/Endodontic office. If I need anything in the future, this is my go-to place! 10/10!!!”

“I was having an after hours emergency this weekend. I was called Monday morning with no appointment and advised to come right in. Dr. Jonsson immediately brought me back, managed my pain and then gave me the root canal, expanding what he was doing every step to make sure I was comfortable. I cannot express enough gratitude to the compassion and swiftness Dr. Jonsson provided me with no appointment first thing on a Monday morning.”

★★★★★

“Every step of my root canal went smoothly and comfortably. From the admin staff and professional set up of my appointment, to Dr. Jonsson and his very calming demeanor, thorough explanation, and truly gifted skills. Literally the only discomfort during the entire process was the tiny bit during numbing and then a bit of soreness a few hours later. Dr. Jonsson even followed up later that night to see how I was feeling.”

Tammy Skenderian

★★★★★

“Dr. Jonsson is THE BEST endodontist! He successfully resolved a problem with an old root canal that had been done a few years ago by a previous dentist. It had been giving me pain for over a year, and other dentists were unable to solve the problem. Thanks to Dr. Jonsson's expertise, I am finally pain-free.”

“I do biopsies for a living as a physician and I can tell you good from bad almost immediately. I noticed when Dr Jonsson stepped in the room he just looks capable. The procedure was explained very clearly and honestly I never felt anything. I can't imagine his procedure being any better than it was — no pain, I can eat fine. I give this guy a 10.”

William Smith

“Dr. Jonsson was very thorough and explained all aspects. There were no surprises. He even apologized for a long appointment but I was thrilled to have it accomplished in 1 visit. He texted me that night and the next morning to follow up on my status. I felt very well cared for!”

“I am notoriously difficult to numb and have a tremendous level of anxiety related to even routine dental procedures. This particular tooth was one of the most difficult to numb and treat. I can say with some certainty that if I had to have this done, I'm very glad it was done here. Dr. Jonsson was exceptional in every way.”

Chris Siino

Courtney Vogel

“My tooth with a 20-year-old root canal needed additional attention. Dr. Jonsson explained the benefits of a new root canal procedure using today's technologies and was able to do that immediately.

Raymond Fenwick

★★★★★

“I have had two root canals here. Everyone is really nice and Dr. Jonsson is just amazing. Pain free and so easy. I have dental fears and TMJ which can make dental work challenging. Both root canals went so well I was shocked. They deserve more than 5 stars!”

Brenda Whitney

★★★★★

“Dr. Jonsson is outstanding! He thoroughly explained every step of the procedure and made me feel completely comfortable. He made sure I wasn't in pain, and he was perfect at giving the numbing shots (which are usually a painful experience for me). His assistant Emily was also great, and the front desk staff were very friendly and professional.”
