Root canal treatment does not deserve its reputation for being painful. In reality, the procedure relieves the severe pain caused by an infected or inflamed tooth nerve, and with modern techniques and anesthesia, most patients report that the experience is no more uncomfortable than getting a filling. If you are looking for a trusted Dental Clinic in Barrie, understanding the facts about root canal treatment can remove the anxiety that leads many patients to delay care and allow problems to worsen.
This article addresses the most persistent myths about root canal treatment and replaces them with accurate information based on current dental practice.
Ardagh Family Dentistry, recognized as one of the best dental clinics in Barrie for comprehensive Dental Care in Barrie, approaches root canal treatment with patient comfort as a top priority, using updated techniques that make the procedure routine and well‑tolerated.
What Is a Root Canal?
A root canal (formally known as endodontic treatment) is a procedure that removes infected or inflamed pulp tissue from inside a tooth. The pulp is the soft inner core of the tooth containing nerves and blood vessels. When this tissue becomes infected due to deep decay, a crack, or repeated dental work on the same tooth, it causes significant pain and can lead to abscess formation if untreated.
During root canal treatment, the dental team:
-
Administers local anesthesia to completely numb the tooth and surrounding area
-
Creates a small access opening in the top of the tooth
-
Uses fine instruments called files to remove the infected pulp tissue and shape the root canals
-
Cleans and disinfects the canals thoroughly with antimicrobial solutions
-
Fills the canals with a biocompatible material called gutta‑percha
-
Seals the access opening with a temporary or permanent filling
In most cases, a crown is placed over the tooth following root canal treatment to restore its strength and protect it from fracture.
Common Root Canal Myths
Myth 1: Root Canals Are Extremely Painful
This is by far the most pervasive myth. The pain patients associate with a root canal is the pain they felt before the procedure, from the infected or inflamed nerve inside the tooth. The root canal itself eliminates that source of pain.
With modern local anesthetics, the procedure is comfortable for the vast majority of patients. Dentists can also offer supplemental anesthetic techniques for teeth that are more difficult to anesthetize due to severe infection. Some post‑procedure soreness is normal as the tissue heals, but this is managed easily with over‑the‑counter pain relief.
Myth 2: It Is Better to Have a Tooth Pulled Than Get a Root Canal
Tooth extraction is not a superior alternative to root canal treatment. Saving a natural tooth is almost always the better long‑term outcome. Extracting a tooth creates a gap that allows adjacent teeth to shift, alters your bite, and can lead to bone loss at the site of the missing tooth.
Replacing an extracted tooth with an implant, bridge, or denture adds additional procedures and cost. Root canal treatment followed by a crown preserves the natural tooth and its root, maintaining bone volume and function without requiring replacement.
Myth 3: Root Canals Cause Illness
An outdated and scientifically discredited theory from the early 1900s claimed that bacteria from root canal‑treated teeth could spread through the body and cause systemic disease. This theory has been thoroughly disproven by modern research. Root canal treatment removes infection from the tooth and the surrounding environment, it does not create or spread it. The procedure is safe and effective.

Myth 4: A Root Canal Kills the Tooth
A root canal removes the pulp tissue from inside the tooth, which does remove the nerve sensation. However, the tooth remains structurally intact and continues to function normally for chewing and speaking. It is attached to the jawbone via the periodontal ligament and is not dead in the functional sense. Teeth that have received root canal treatment can last a lifetime with proper care.
Myth 5: You Only Need a Root Canal If Your Tooth Hurts
Not all teeth that need root canal treatment cause noticeable pain. In some cases, the nerve has already died (pulp necrosis), and the patient has no acute pain even though an infection is present. The infection can show up on X‑rays as a darkening at the root tip, called a periapical lesion. Regular dental check‑ups and X‑rays are essential for catching these situations before they escalate.
Myth 6: Root Canal Treatment Requires Many Appointments
While complex cases may require two appointments, many root canals can be completed in a single visit that lasts approximately 60 to 90 minutes. Simple single‑rooted teeth with uncomplicated anatomy are often treated in one session. Multi‑rooted teeth such as upper molars may require two appointments to ensure thorough cleaning.
Signs You May Need a Root Canal
-
Persistent, severe toothache that throbs or intensifies when lying down
-
Sensitivity to heat or cold that lingers after the stimulus is removed
-
Swelling in the gums near a specific tooth, or a pimple‑like bump (fistula) on the gum
-
Darkening or discoloration of a tooth
-
Pain when biting or chewing on one specific tooth
-
A previous large filling that is failing or a tooth with repeated dental work
What to Expect After the Procedure
Some tenderness and sensitivity in the treated tooth and surrounding gum tissue for two to five days is normal. This reflects the body’s healing response to the procedure, not ongoing infection. Most patients can return to normal activities the same day and manage any discomfort with ibuprofen or acetaminophen.
The tooth will need a crown placement shortly after root canal treatment to prevent fracture and restore full function. Until the crown is placed, avoid chewing hard foods on the treated side.
Common Patient Mistakes
-
Delaying treatment for months after symptoms appear, leading to a more advanced infection and harder‑to‑treat abscess
-
Stopping antibiotics early when symptoms improve before completing the full course
-
Avoiding the dentist due to fear of pain based on outdated assumptions about the procedure
-
Not returning for crown placement after root canal treatment, leaving the tooth vulnerable to fracture
-
Assuming a painless tooth does not have an infection
Frequently Asked Questions
Q1: How long does a root canal appointment take? A typical root canal appointment lasts between 60 and 90 minutes for a single‑rooted tooth. Multi‑rooted teeth or cases with complex anatomy may take longer or require a second appointment.
Q2: Can I drive home after a root canal? If only local anesthesia was used, you can drive yourself home once the numbness begins to wear off and you feel comfortable. If sedation was used, arrange for someone to drive you.
Q3: How long does a root canal‑treated tooth last? With a properly placed crown and good oral hygiene, a root canal‑treated tooth can last the rest of your life. Regular check‑ups are important to monitor the tooth and the surrounding bone.
Q4: Is a root canal covered by dental insurance? Many insurance plans cover a portion of root canal treatment as it is classified as a restorative procedure. Coverage percentages and limitations vary by plan. Check with your insurer before treatment for specific details.
Q5: What happens if I do not get a root canal when I need one? The infection will progress, causing increasing pain, swelling, and abscess formation. Eventually, the tooth may need to be extracted, and the infection can potentially spread to surrounding bone or soft tissue if left untreated for an extended period.
Conclusion
Root canal treatment is one of the most effective and misunderstood procedures in dentistry. It saves natural teeth, eliminates infection, and relieves severe pain. The fear surrounding root canals is largely rooted in outdated information that does not reflect modern dental techniques and anesthesia.
