Root Canal Retreatment vs. Apicoectomy: What’s the Difference?

A root canal is meant to save your tooth and end the pain, so it’s frustrating when problems come back months or even years later. You might notice tooth pain when you chew or bite down. Swollen gums or a small bump near the treated tooth can also mean an infection has returned. 

In many cases, you can still keep the tooth. The two most common options are retreatment and an apicoectomy. Retreatment redoes the root canal through the top of the tooth, while an apicoectomy is a minor surgery that treats the infection at the tip of the root. 

At Endodontic Associates of East Alabama in Auburn, AL, our team helps patients choose the right treatment to keep their natural teeth. Call today to schedule a consultation. 

How root canal retreatment works 

Root canal retreatment is usually the first option when a treated tooth becomes infected again. A root canal can fail for several reasons, such as a narrow or curved canal that was hard to find the first time, a crown that was placed too late, or new decay that lets bacteria back into the tooth. 

During treatment, the endodontist reopens the tooth through the crown or filling, removes the old filling material, and cleans the canals. Using magnification, they check for extra canals or cracks before refilling and sealing the tooth. You’ll then see your general dentist for a new crown or filling to protect it. Mild tooth sensitivity for a few days afterward is normal. 

When an apicoectomy procedure is the better choice 

Sometimes the problem can’t be reached from the top of the tooth. A canal may be blocked or too narrow, or the tooth may have a large crown that would be risky to remove. An apicoectomy may also be recommended when infection lingers after retreatment. 

During an apicoectomy procedure in Auburn, local anesthesia numbs the area, and a small opening is made in the gum near the root. The infected tissue and the very tip of the root are removed, and a small filling is placed to seal the end of the root. A few stitches help the gum heal. 

Recovery takes a little longer than with retreatment. Swollen gums and soreness are common and usually fade within about two weeks. Some tooth sensitivity is also normal while the area heals. Stitches are typically removed at a follow-up visit about a week later. 

What to expect at your consultation 

At your visit, we’ll find out why the tooth is still causing problems and which treatment makes the most sense. Your visit usually includes:  

  • Symptom review: We’ll ask about your tooth pain, when it started, and what makes it worse. 
  • Exam: The tooth and nearby gums are checked for tenderness, swollen gums, or signs of infection. 
  • X-rays: Images help show the shape of the roots and whether infection is present near the tip. 
  • Treatment plan: Once we know the cause, we’ll walk you through your options and what recovery will look like. 

Be sure to mention any tooth sensitivity to hot or cold, even if it seems minor. Our team can explain each step clearly before any treatment begins.

Great "bedside manner" - Dr. Looney was professional, kind and attentive. He listened so carefully that he addressed questions that I hadn't actually asked, but he intuitively knew I wanted answers to. He read my forms and asked questions about my prior career, showing interest. He was kind, proactive and made sure I left my appointment with everything I needed. The procedure was done efficiently with as little discimfort as possible. I strongly recommend Dr. Looney if you want a quality and caring experience. I drove 220 miles round trip and it was well worth it!

Dr. Looney took great care with this very anxious patient. I would definitely see him again.

This doctor is very caring. He went above and beyond to get my pain under control. I had one root canal and continued to have pain. He saw me (without a scheduled appointment) and did another root canal on a tooth next to the first infected one. I am praying this will resolve the issues but if not, it is certainly not a reflection on Dr. Looney. He has thorough, quick and most of all, compassionate. The office personnel were great as well.

My dentist did a root canal about 20 years ago and for some reason it went bad and he recommended that I see a specialist because of the difficulty of redoing one. I choose Dr. Looney from my dentist's recommendation and because his practice accepted my Southland Dental Insurance. The Dr. and his assistants did a great job, my root canal went fine, and my insurance covered the entire amount due, I was even refunded the co-pay. I hope I never need another one, but if I do I will see Dr Looney.
