Understanding Root Canal Retreatment
Sometimes, the teeth don’t heal properly after a root canal procedure. When this occurs, the patient may experience pain and reinfection of the tooth. A root canal or endodontic retreatment can be done to remove this new infection and save the natural tooth.
Can A Root Canal Be Redone?
Yes, a root canal retreatment can be redone. In the case of a complication, such as reinfection, the retreatment can involve removing the infection and sealing the area again. With that said, additional canals are uncommon, and most root canal treatments are successful (97% in the first ten years).
Top Reasons Why Root Canals Need To Be Redone
A root canal is typically redone due to tooth decay or trauma that causes reinfection. Bacteria may seep into the root canal through decay or exposure, leading to the development of the infection.
The most common reasons for root canal retreatment include:
- New tooth decay
- Trauma
- Reinfection from bacteria
- Undetected canals
- Cracked tooth
The Process Of Root Canal Retreatment
During the root canal retreatment, a dental professional (a dentist or endodontist) will remove any original root canal filling material from the last procedure to access the canal. They will thoroughly clean the area and examine it for other problems that may have occurred.
Following this, your dentist will refill the area with a special sealing material and seal the top of the tooth. After the infection is dealt with and the area is filled and sealed, your dentist will place a new custom-designed crown over the tooth to restore it to its original form.
Tips On How To Properly Care For Your Root Canal
After your procedure, your doctor can prescribe medication to help with the short-term pain and will recommend that you avoid hard and crunchy foods. It’s important to maintain good oral health to keep your root canal and the rest of your teeth and gums in good shape. This means brushing twice daily, flossing once a day, and continuing to schedule regular dentist visits.
Root Canal Retreatment FAQ
Yes, tooth decay or trauma can allow plaque and bacteria to seep into the root canal, reinfecting the area. In this case, you can have a root canal retreatment to remove the infection.
A failed root canal may result in prolonged tooth sensitivity, especially when biting down, a pimple or boil on the jaw, tooth discoloration, or pain and pressure on the previously treated tooth. If you suspect you may have a failed root canal, consult with your dentist to discuss next steps.
It’s normal to experience some pain and discomfort in the first few days after being treated with a root canal. If the pain lasts longer than this, contact your dentist for an evaluation. Pain months or even years after a root canal can also suggest a reinfection that needs treatment.
Root canal treatment typically hurts no more than a routine filling with local anesthesia. You might experience some discomfort or soreness post-procedure, but this can be managed with over-the-counter pain relievers.
Depending on the tooth, it usually takes about 1-2 hours, as molars may take longer than a front tooth. More complex teeth may take a couple of visits to complete.
The common alternative is tooth extraction, typically followed by a dental implant or dental bridge.
A treated tooth can last a lifetime if you practice good oral hygiene and have regular dental visits. Crowns or fillings help further protect the tooth.
