How Long Does a Root Canal Last?

Root canal treatment is designed to treat an infection in a tooth’s pulp. If you’ve just had a root canal filling or you’re currently dealing with a tooth infection, you might have a few unanswered questions about root canal treatment, including how long root canals last.

As well as explaining how long a root canal lasts, we’ll cover some commonly asked questions about root canal therapy.

The quick answer is that the effects of a root canal procedure could last from a few years to a lifetime. However, several factors can influence the longevity or success of your treatment. We’ll explain more about this later.

If you think you might have an infection and need dental treatment, don’t delay. Getting seen as soon as possible by an endodontist could preserve your natural tooth and avoid more complex treatment in the future.

What is a Root Canal Treatment?

A root canal is a dental procedure to treat an infected tooth. It’s necessary when the infection is deep within the tooth pulp. This infection can arise due to decay, repeated dental procedures on the tooth, or trauma that has caused damage to the area.

Treatment involves removing the infected or damaged pulp tissue from inside the tooth and cleaning and disinfecting the root canals.

Once the infected pulp is removed and the space has been thoroughly cleaned and shaped, the tooth will be sealed with a biocompatible material. This helps prevent further infection and allows for restoration of function through subsequent treatments, such as a dental crown or filling.

Average Lifespan of a Root Canal: What to Expect Over Time

The success rate of root canal treatments is impressively high, often cited at around 85% to 97%. For most patients, root canal treatment effectively alleviates pain and addresses infection within the tooth.

Generally speaking, a root canal can last anywhere from 10 to 15 years, although many patients report their treated teeth remaining functional for much longer with proper care.

The longevity of a root canal treatment can be influenced by several key factors that contribute to the overall health of the tooth and surrounding tissues.

Factors Influencing the Longevity of a Root Canal Treatment

When it comes to the average lifespan of a root canal, several factors come into play that can influence how long the treatment will last and the overall health of the treated tooth.

Quality of Materials

First and foremost, the quality of materials used during the procedure plays a significant role. High-quality filling materials and sealants can create a more effective barrier against bacterial invasion, reducing the risk of reinfection.

Oral Hygiene

Your oral hygiene practices are critical in maintaining tooth health post-treatment. Routine brushing, flossing, and regular dental checkups help prevent complications that could compromise the integrity of the treated tooth.

Poor oral hygiene can lead to gum disease or decay around adjacent teeth, which may ultimately affect the longevity of the root canal.

Type of Treatment

Specialist endodontic treatment of a damaged tooth typically has a higher success rate and a longer lifespan for the treated tooth than a root canal carried out by a general dentist.

Location of the Affected Tooth

Where the tooth is, such as the front or back teeth, can also affect the lifespan of treatment. Front teeth have only one root canal and tend to last longer due to less pressure and bite force.

Lifestyle Choices

Dental care habits also extend to lifestyle choices such as diet and smoking. A balanced diet rich in nutrients supports oral health, while smoking has been shown to negatively impact healing processes and increase susceptibility to infections.

Preventative Dental Care

Your ongoing dental care habits play an essential role in ensuring long-term success after a root canal procedure. Engaging in preventive care measures—such as using fluoride toothpaste or mouth rinses—can further protect against decay.

Biological Factors

Your age and overall health may influence how well your body responds post-treatment. Understanding these multifaceted influences is vital for patients and practitioners aiming for optimal outcomes.

What happens if I don’t treat an infected tooth?

If left untreated, the infected tooth pulp could lead to severe pain and the formation of an abscess. When this happens, you may need to have the tooth removed.

Early prevention or root canal treatment could preserve your natural teeth. This is the best-case scenario because retaining the tooth will help to maintain the alignment of your other teeth as well as help you to chew properly. It’s also beneficial for your overall oral health.

I need a root canal, will it be painful?

Advancements in dentistry have made procedures like root canals much more comfortable. You will be given an anaesthetic to alleviate any pain and modern techniques also minimise discomfort.

Don’t let the thought of pain put you off caring for your dental health. Many dentists including those at Vogue Dental are specialists in treating nervous patients and offer conscious sedation as an option.

Signs of Root Canal Fails

If you are experiencing sensitivity to hot or cold liquids, pain or swelling around a root canal-treated tooth, it could be a sign that root canal treatment has been unsuccessful.

Any dental crowns that have been placed may need to be removed so that the tooth root can be cleaned and any remaining dental pulp tissue removed.

If you think you have a failed root canal, contact your dentist right away. They will be able to check on the success of your endodontic treatment and take the necessary steps to correct any issues.
