Don't Let a Missing Tooth Hold You Back in Life

Root Canal Retreatment: What To Do If Your Previous Root Canal Procedure Fails

by Wyatt Morgan

Root canal retreatment is a dental procedure that involves removing the filling material and restoring a previously treated tooth that has failed to heal or has developed new problems. Root canals are generally a very effective treatment for infected or damaged teeth, but in some cases, the initial procedure may not be successful. If you have had a previous root canal procedure that has failed, retreatment may be necessary. Here's what you need to know:

Signs That You Need Retreatment

The signs that you may need root canal retreatment are similar to those that you experienced before the initial root canal procedure. Some of the signs to look out for include pain, swelling, and sensitivity to hot and cold temperatures. If you notice any of these signs, it is important to see your dentist or endodontist as soon as possible.

The Retreatment Procedure

The retreatment procedure is similar to the initial root canal procedure, but it is generally more complex and may take longer to complete. The first step is to remove the filling material from the tooth, and then the endodontist will clean and disinfect the root canal. If there is an infection, antibiotics may be prescribed to help clear it up. Once the root canal is clean, the endodontist will refill and seal the tooth.


After root canal retreatment, it is important to take care of your tooth and follow your endodontist's instructions for aftercare. You may experience some discomfort and sensitivity for a few days, but this should subside. It is important to continue brushing and flossing regularly and to avoid chewing on hard or sticky foods for a few days.


The best way to prevent the need for root canal retreatment is to take good care of your teeth and gums. This includes brushing twice a day, flossing regularly, and visiting your dentist or endodontist for regular checkups and cleanings. It is also important to avoid chewing on hard objects or using your teeth as tools, as this can cause damage and infection.

If you experience any signs of pain or infection after a root canal procedure, it is important to see your dentist or endodontist as soon as possible. With proper aftercare and prevention, you can reduce the risk of needing retreatment and maintain good oral health for years to come.

If you suspect that a previous root canal procedure has failed, it's important to schedule an appointment with your dentist as soon as possible — like most dental health issues, this condition will progressively get worse if not treated.
