What Is Endodontic Retreatment?

Simply put, endodontic retreatment is a procedure performed on a tooth that has already undergone root canal therapy. It involves re-opening the tooth so that we can check for the underlying source of the issue. Normally, this means looking for additional root canals that may have been missed during the initial treatment or any other unusual aspects of the tooth’s anatomy. With endodontic retreatment, we can make it more likely that you’ll be able to keep your tooth for years to come.
Why Would I Need Endodontic Retreatment?
One of the biggest signs that you need endodontic retreatment is if you start experiencing pain in a tooth that previously received root canal treatment. Additionally, the procedure may be necessary if there are any telltale signs of a new infection, such as an abscess forming near the tooth in question. It’s best to call our dental office immediately if you suspect endodontic retreatment is necessary; the longer you wait, the more likely it is that the entire tooth will be compromised.
The Endodontic Retreatment Process
Just like with root canal therapy, we will numb your mouth to keep you comfortable during your endodontic retreatment. Your dental crown will be removed, and the biocompatible filling material will be taken out of the tooth. After a careful examination, we will remove any infection we find and give the inside of your tooth a thorough cleaning. Afterward, the tooth will be refilled. We may schedule a follow-up appointment to make sure your mouth is recovering properly.
Root Canal Retreatment FAQs
Why do root canals fail?
Even though root canal treatments are designed to preserve your tooth for a lifetime, there are several factors that could cause it to become reinfected or to develop other complications, including:
- Incomplete cleaning of the root canals during the initial treatment.
- New infection, decay, or damage.
- Waiting too long to place the crown or filling can allow bacteria back into the root canals.
- Fractured tooth roots can allow bacteria to bypass the treated area, causing reinfection.
What are the warning signs that I may need a root canal retreatment?
A failed root canal may not always cause immediate symptoms, however there are some warning signs to look out for, including:
- Persistent or recurring pain in the previously treated tooth.
- Gum swelling or tenderness surrounding the treated tooth.
- A dental abscess on the gums.
- Sudden sensitivity to hot or cold.
- Discoloration of the previously treated tooth.
Should you notice any of these signs, please contact your dentist as soon as possible.
What will happen during a root canal retreatment?
A root canal retreatment is very similar to an initial root canal, but it involves a few extra steps to remove any remaining infection from the tooth.
First, your dentist will reopen the tooth by removing the existing crown or filling. Then, the old filling materials will be cleared out so the root canals can be thoroughly re-cleaned. Next, the tooth will be disinfected, filled with new sealing materials, and a new crown or filling will be placed to restore and protect it.
Is a tooth extraction better than a root canal retreatment?
Although it might seem like a waste of time and money to get a root canal retreatment, the truth is that it may actually be easier and more affordable to have the tooth retreated. That’s because if given the option, it’s always best to preserve your natural teeth. Not only will real teeth continue to stimulate the jaw and protect your other teeth, but having the infected tooth removed will require additional costs such as replacement, which can be very expensive.
