Few phrases in dentistry inspire as much dread as "you need a root canal." The mere mention of the procedure conjures images of excruciating pain and prolonged suffering. But here is the reality: modern root canal treatment is nothing like its reputation. As a dentist at Purple Ice Consults Dental Clinic in Port Harcourt, I have performed numerous root canal procedures, and the response from patients afterward is almost always the same — "That was not nearly as bad as I expected."
The myths surrounding root canal treatment have persisted for decades, largely based on outdated techniques and anecdotal horror stories. It is time to set the record straight.
Myth 1: Root Canal Treatment Is Extremely Painful
This is the most pervasive myth, and it is simply false. The purpose of root canal treatment is to eliminate pain, not cause it. By the time a patient needs a root canal, they are usually already in significant pain due to an infected or inflamed pulp inside the tooth. The procedure removes the source of that pain.
Modern root canal treatment is performed under effective local anesthesia. Patients should feel no pain during the procedure — only pressure and vibration from the instruments. The experience is comparable to having a filling done. After the procedure, some mild soreness is normal for a few days, but this is easily managed with over-the-counter pain medication.
The idea that root canals are painful comes from an era before modern anesthetic techniques and instruments. With today's technology, including flexible nickel-titanium rotary files, electronic apex locators, and advanced local anesthetics, the procedure is efficient, precise, and comfortable.
Myth 2: It Is Better to Just Extract the Tooth
Some patients, driven by fear of root canal treatment or the perceived simplicity of extraction, ask to have the tooth removed instead. While extraction is sometimes necessary, preserving the natural tooth is almost always the better option when it is feasible.
Your natural teeth are irreplaceable. No artificial replacement — whether implant, bridge, or denture — can fully replicate the function, feel, and proprioception of a natural tooth. Extraction also leads to bone loss in the area, potential shifting of adjacent teeth, and the cost of a replacement restoration.
A root canal-treated tooth, when properly restored with a crown, can function normally for many years, often for the rest of the patient's life. The success rate of root canal treatment is approximately ninety to ninety-five percent, making it one of the most predictable procedures in dentistry.
Myth 3: Root Canal Treatment Causes Illness
This myth originates from long-debunked research from the early twentieth century. Dr. Weston Price proposed in the 1920s that root canal-treated teeth harbored bacteria that could cause systemic diseases. This theory has been thoroughly discredited by modern science. Extensive research by the American Association of Endodontists and other reputable organizations has found no valid scientific evidence linking root canal treatment to disease elsewhere in the body.
In fact, the opposite is true — leaving an infected tooth untreated poses a genuine risk of the infection spreading to other areas, including the surrounding bone, the fascial spaces of the face and neck, and in rare but documented cases, the bloodstream and brain.
What Exactly Happens During a Root Canal?
Understanding the procedure demystifies it. Here is what happens step by step:
Diagnosis. The dentist examines the tooth clinically and takes X-rays to assess the extent of infection and the anatomy of the root canals.
Anesthesia. Local anesthesia is administered to numb the tooth and surrounding area completely.
Access Opening. A small opening is made in the crown of the tooth to access the pulp chamber.
Pulp Removal. The infected or inflamed pulp tissue is carefully removed from the pulp chamber and root canals using specialized instruments.
Cleaning and Shaping. The empty canals are cleaned, disinfected, and shaped to receive a filling material. Irrigating solutions such as sodium hypochlorite are used to flush out bacteria and debris.
Filling. The canals are filled with a biocompatible material called gutta-percha, which seals the space and prevents reinfection.
Restoration. The access opening is sealed, and in most cases, a crown is placed over the tooth to protect it and restore its full function. A root canal-treated tooth is more brittle than a vital tooth, so a crown is essential for long-term success.
Signs You May Need a Root Canal
Not every toothache means you need a root canal, but certain symptoms should prompt an immediate dental visit. These include severe, spontaneous toothache that may wake you at night, prolonged sensitivity to hot or cold that lingers after the stimulus is removed, pain when biting or chewing, swelling of the gum near the affected tooth, a pimple-like bump on the gum that may drain pus, and darkening or discoloration of the tooth.
Some teeth that need root canals show no symptoms at all and are discovered during routine X-rays. This is yet another reason why regular dental check-ups are so important.
After the Root Canal
Recovery after root canal treatment is typically straightforward. You may experience some tenderness for a few days, which can be managed with ibuprofen or acetaminophen. Avoid chewing on the treated tooth until the final restoration (crown) is placed. Maintain your regular oral hygiene routine and attend your follow-up appointments.
At Purple Ice Consults Dental Clinic, we use modern techniques and materials to ensure every root canal treatment is as comfortable and effective as possible. If you are experiencing tooth pain, please do not let fear prevent you from seeking treatment. The sooner an infected tooth is treated, the better the outcome — and I promise, it is not as bad as you think.
