Root canal treatment is a common dental procedure that saves millions of teeth each year. However, it's often surrounded by misconceptions that can cause unnecessary fear and anxiety. In this article, we'll address the most common myths about root canal treatment and provide you with accurate, evidence-based information to help you make informed decisions about your dental health.
Myth 1: Root Canal Treatment is Extremely Painful
This is perhaps the most pervasive myth about root canal treatment. In reality:
- Modern anaesthesia techniques ensure you'll be comfortable during the procedure
- Most patients report that root canal treatment is no more uncomfortable than getting a filling
- The treatment actually relieves pain caused by infected or inflamed pulp
According to the British Endodontic Society, root canal treatment is designed to eliminate pain, not cause it.
Myth 2: Root Canal Treatment Causes Illness
This myth originates from discredited research in the 1920s. Current scientific evidence shows:
- There's no valid scientific evidence linking root canal treatment to disease elsewhere in the body
- The myth has been thoroughly debunked by dental and medical communities worldwide
- Root canal treatment actually helps eliminate harmful bacteria from the infected tooth
The National Health Service (NHS) and the British Dental Association confirm the safety and importance of root canal treatment in maintaining overall health.
Myth 3: It's Better to Extract the Tooth Than Have a Root Canal
Saving your natural tooth through root canal treatment is almost always the best option. Here's why:
- Natural teeth are better for chewing and maintaining proper bite alignment
- Root canal treated teeth can last a lifetime with proper care
- Tooth extraction can lead to other dental problems and may require more extensive, costly treatments
The General Dental Council advises that preserving natural teeth should be a priority when possible.
Myth 4: Root Canal Treatment is Only Needed When There's Pain
While pain can be a sign that you need root canal treatment, it's not the only indicator:
- Some teeth needing root canal treatment may not cause any pain
- Regular dental check-ups can identify problems before they become painful
- Early intervention often leads to better outcomes and simpler treatments
The NHS recommends regular dental check-ups to catch potential issues early, even before symptoms appear.
Myth 5: Root Canal Treatment Kills the Tooth
This myth misunderstands the nature of tooth vitality:
- A tooth's vitality comes from the supporting tissues, not just the inner pulp
- After root canal treatment, the tooth continues to receive nourishment from surrounding tissues
- Treated teeth can function effectively for many years, often for a lifetime
The British Endodontic Society emphasises that root canal treatment is a tooth-saving procedure, not a tooth-killing one.
Myth 6: Root Canal Treatment Takes Multiple Appointments
Advancements in dental technology have streamlined the root canal process:
- Many root canal treatments can be completed in a single visit
- The number of appointments depends on the complexity of the case and the tooth's condition
- Modern techniques and equipment have significantly reduced treatment time
Your dentist can provide a more accurate timeline based on your specific case.
Myth 7: Root Canal Treatment is Expensive
While costs can vary, root canal treatment is often a cost-effective option:
- NHS dental charges for root canal treatment fall under Band 2, currently £65.20 (as of 2023)
- Private treatment costs vary but are often less expensive than tooth extraction followed by implant or bridge placement
- Saving a natural tooth can prevent future dental problems and expenses

Myth 8: Root Canals Often Fail
Root canal treatment has a high success rate:
- According to the British Endodontic Society, success rates for initial root canal treatment are up to 90%
- Proper restoration (e.g., crown placement) after treatment significantly improves long-term success
- Following good oral hygiene practices helps ensure the longevity of treated teeth
Regular follow-ups with your dentist can help monitor the health of treated teeth.
Myth 9: Pregnant Women Can't Have Root Canal Treatment
Root canal treatment is safe during pregnancy:
- The procedure can be performed safely at any stage of pregnancy
- Treating dental infections is crucial for the health of both mother and baby
- Special precautions, such as limiting X-rays, are taken for pregnant patients
The NHS advises that necessary dental treatments should not be delayed due to pregnancy.
Myth 10: You Don't Need a Crown After Root Canal Treatment
In most cases, a crown is essential after root canal treatment:
- Crowns protect the treated tooth from fracture and reinfection
- Back teeth (molars and premolars) almost always require crown placement
- Front teeth may sometimes be restored with less extensive restorations
Your dentist will recommend the most appropriate type of restoration for your specific case.
The Importance of Evidence-Based Dentistry
Evidence-based dentistry is crucial in combating misinformation:
- It relies on the most current and comprehensive scientific evidence
- The General Dental Council requires UK dentists to practice evidence-based dentistry
- Ongoing research continues to improve root canal techniques and outcomes
This approach ensures that dental treatments, including root canals, are both safe and effective.
How to Find Reliable Information About Root Canal Treatment
To ensure you're getting accurate information:

Remember, your dentist is your best resource for personalised advice about your dental health.
