Myth 2: Extraction is Better Than a Root Canal

Another common misconception is that pulling out a problematic tooth is a simpler and more effective solution than undergoing a root canal.

The Truth:

Saving your natural tooth through a root canal is almost always preferable to extraction. Natural teeth function better for chewing, speaking, and maintaining jawbone structure. Extracting a tooth and replacing it with a bridge or implant can be more costly, time-consuming, and invasive. Learn more about saving your natural teeth: Root Canal Treatment vs Extraction

Myth 3: Root Canals Cause Illness

This myth originates from outdated and debunked research in the early 1900s, suggesting that root canal-treated teeth could harbour harmful bacteria and lead to systemic illnesses.

The Truth:

There is no scientific evidence linking root canals to systemic diseases. Advances in sterilisation techniques and dental materials ensure that the procedure is safe and effective. According to the NHS, a root canal eliminates infection from the tooth while maintaining oral and overall health. 

Myth 4: Root Canals Kill the Tooth

Some people mistakenly believe that a root canal kills the tooth, leaving it brittle and prone to breaking.

The Truth:

While the root canal removes the tooth’s nerve and pulp to eliminate infection, the tooth itself remains alive through surrounding tissues and ligaments. Proper restoration, such as a crown, can reinforce the tooth’s structure and longevity by protecting it from fractures and decay. The crown acts as a protective barrier, restoring the tooth’s functionality and appearance. Treated teeth, when paired with consistent dental care and routine check-ups, can last a lifetime with good oral hygiene practices. Regular brushing, flossing, and avoiding excessive pressure, like grinding, are essential to ensure the long-term success of the treated tooth.

Myth 5: Root Canals Take Multiple Visits

The idea that root canal treatment requires numerous visits deters many patients.

The Truth:

While complex cases may need additional visits, most root canals can be completed in one or two appointments.

Modern root canal treatments have benefited immensely from cutting-edge technology. One such innovation is the use of dental operating microscopes, which provide magnification and illumination, allowing dentists to identify complex root structures and hidden canals that would otherwise be missed. This enhances the precision and success rates of the procedure.

Another game-changer is cone-beam computed tomography (CBCT) imaging. CBCT scans produce 3D images of the tooth and surrounding structures, offering unparalleled detail. This advanced imaging helps in diagnosing complicated cases, planning treatment, and avoiding potential complications. These technologies ensure a more thorough and efficient root canal treatment, reducing the likelihood of reinfection and ensuring optimal outcomes. Your dentist or endodontist will evaluate your specific case to minimise treatment time without compromising quality.

Myth 6: Root Canals Have Low Success Rates

Patients sometimes worry that a root canal might fail, leading to further complications or even tooth loss.

The Truth:

Root canal treatments have a success rate of over 95% when performed by experienced Endodontists. The key to a successful outcome lies in proper diagnosis, skilful execution, and adequate post-procedure care. Modern dental technology, such as digital imaging and rotary instruments, enhances precision and outcomes. Root canal treatments are highly successful, with studies indicating success rates ranging from 85% to 97%. The NHS reports that approximately 9 out of 10 root-treated teeth survive for 8 to 10 years Root Canal Treatment – Information for Patients

Factors influencing these rates include the tooth’s condition, the dentist’s expertise, and adherence to post-treatment care. Advancements in dental technology, such as dental operating microscopes and cone-beam computed tomography (CBCT) imaging, have further enhanced the precision and outcomes of root canal procedures. These tools allow for better visualization and treatment of complex root structures, contributing to higher success rates. It’s essential to consult with a qualified endodontist to assess individual cases and ensure optimal treatment outcomes.

Myth 7: Root Canals Lead to Recurring Infections

Some individuals fear that root canal-treated teeth are more susceptible to reinfection.

The Truth:

A properly done root canal effectively seals the tooth to prevent future infections. However, reinfection can occur if the restoration (e.g., crown) is delayed or improperly fitted. Additionally, inadequate oral hygiene or the presence of an untreated crack in the tooth can increase the risk of reinfection. Regular dental check-ups and timely restorations, such as crowns, are crucial in maintaining the integrity of the treated tooth. Following your dentist’s recommendations for aftercare significantly reduces this risk and ensures the long-term success of the procedure.

Myth 8: Root Canals Are Too Expensive

Cost is a significant concern for many patients, leading to the belief that root canals are prohibitively expensive compared to extractions.

The Truth:

While root canal treatments involve an upfront cost, they are a long-term investment in oral health. Extraction and replacement options like implants often cost significantly more over time. Dental insurance frequently covers part of the expense, making root canals an affordable choice for preserving natural teeth.

Root canal treatment is a vital procedure that saves millions of teeth annually. By debunking these myths, understanding technological advancements, and recognising the reality, patients can make informed decisions about their oral health without unnecessary fear or hesitation. If you have concerns, consult your dentist or endodontist to explore the most suitable options for your dental concern. Root canals are a well-established, safe, and effective treatment that preserves natural teeth and enhances oral health outcomes.
