Why the Root Canal Treatment is Important: A Definitive Guide

For many years, root canal therapy has been associated with intense pain and long, uncomfortable dental appointments. This procedure is often misunderstood, but it is a cornerstone of modern dentistry, helping to relieve tooth pain and protect teeth. Many people are frightened and anxious about root canals, mainly because of outdated information and misconceptions. As a dental professional, I must demystify, explain, and explain the substantial benefits of this essential procedure. As we discuss root canal treatment, I hope to address common fears, explain the reason for root canal therapy, and explain each step of the procedure so you feel informed and at ease.

Addressing Common Anxieties

One of the most significant hurdles in root canal therapy is the anxiety many patients feel. This fear often stems from misconceptions and outdated information.

Root Canals Are Painful

The notion that root canals are excruciatingly painful is perhaps the most pervasive myth. While this may have been true decades ago, advancements in dental technology and anaesthesia mean that today's root canal procedures are virtually pain-free. The pain leading to the need for a root canal, usually due to an infected or abscessed tooth, is often far worse than any discomfort experienced during the procedure itself.

Root Canals Cause Illness

Another common myth is that root canals can cause illness elsewhere in the body. This misconception originated from outdated and debunked research from the early 20th century. Modern science and numerous studies have shown no correlation between root canal therapy and systemic diseases.

Why Root Canal Therapy Might Be Necessary

Root canal therapy becomes necessary when the pulp of the tooth, which contains nerves and blood vessels, becomes inflamed or infected. This can be caused by deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. Trauma to the face can also damage the pulp, even if the tooth has no visible chips or cracks.

If left untreated, an infected pulp can cause severe pain or lead to an abscess. The infection can spread, causing swelling of the face, neck, or head, bone loss around the tip of the root, and drainage problems extending outward from the root. In these cases, a root canal is the best option to eliminate the infection, alleviate pain, and save the natural tooth.

The Root Canal Procedure: A Step-by-Step Guide

Understanding the root canal procedure can help alleviate some of the anxiety associated with it. Here’s a simple breakdown:

  1. Consultation and Diagnosis: Your dentist will first conduct a thorough examination, which may include X-rays, to determine the extent of the infection and the condition of the tooth.
  2. Anaesthesia: Before starting the procedure, local anaesthesia is administered to numb the tooth and surrounding area, ensuring a pain-free experience.
  3. Access Opening: A small hole is drilled into the tooth to access the infected pulp.
  4. Removing the Infected Pulp: Using specialised instruments, the dentist will remove the infected or damaged pulp from the tooth's interior.
  5. Cleaning and Shaping the Canals: The empty root canals are then cleaned, disinfected, and shaped to prepare them for filling.
  6. Filling the Canals: The cleaned canals are filled with a biocompatible material, usually gutta-percha, to seal them and prevent future infection.
  7. Sealing the Tooth: A temporary filling is placed to close the access hole, and once the tooth heals, a permanent crown or filling is applied to restore the tooth’s function and appearance.



Benefits of Root Canal Therapy

  • Saving the Natural Tooth

One of the most significant advantages of root canal therapy is that it saves the natural tooth. Preserving your natural teeth is essential for maintaining proper chewing function, preventing other teeth from shifting, and ensuring a natural appearance. Artificial replacements, while effective, can never fully replicate the feel and function of a natural tooth.

  • Pain Relief

Root canal therapy not only eliminates the pain caused by the infection but also prevents future occurrences. Once the infected pulp is removed, the tooth is free from the source of pain, providing significant relief to the patient.

  • Efficient and Cost-Effective

Compared to tooth extraction and the subsequent need for a bridge or implant, root canal therapy is a more efficient and cost-effective solution. It allows for the preservation of the tooth structure and eliminates the need for more complex and expensive dental procedures.


  • Improved Oral Health

By treating the infection promptly, root canal therapy helps prevent the spread of bacteria to adjacent teeth and the rest of the body, promoting overall oral health. It also prevents the jawbone from deteriorating, which can happen when a tooth is missing.


Root canal therapy is a vital dental procedure that has been vastly improved over the years. It is designed to relieve pain, eliminate infection, and save natural teeth. By demystifying the procedure and addressing common anxieties, we hope to alleviate fears and encourage those in need to seek timely treatment.
