- 11 min read
Ask ten people what they fear most about the dentist, and nine of them will say root canals. That fear is understandable, but it is also almost entirely based on outdated information and dental horror stories passed down like folklore. The truth is that root canal therapy today is routinely no more uncomfortable than getting a filling, and avoiding it is what actually causes serious, lasting pain. For patients searching for a root canal St. John's provider, knowing what the procedure actually involves strips away the anxiety and puts you back in control of your oral health decisions.

Key Insight
Explanation
Root canals do not cause pain, they relieve it
The procedure removes the infected pulp that is actually causing the throbbing pain patients experience before treatment.
Modern anesthesia makes the procedure comfortable
Local anesthetics used today are highly effective; most patients report feeling pressure, not pain, during the procedure.
Avoiding a root canal is almost always the worse choice
An untreated infected tooth can spread infection to the jaw, neck, and surrounding teeth, leading to tooth loss and serious health complications.
The procedure typically takes one to two appointments
Straightforward cases are often completed in a single visit of 60 to 90 minutes at a clinic like Stavanger Dental in St. John's.
A crown usually follows root canal therapy
After the pulp is removed, the tooth becomes more brittle and a dental crown protects it from fracturing under biting pressure.
Root canal therapy NL is covered under many plans
Stavanger Dental accepts the Canadian Dental Care Plan, which can significantly offset the cost of endodontic treatment for eligible patients.
Fear, not the procedure, causes most avoidance
Studies consistently show that patients who have had a root canal rate the experience as no worse than having a tooth extracted, and often better.
What Root Canal Therapy Actually Is
Root canal therapy, technically called endodontic treatment, is a procedure that removes the infected or inflamed soft tissue inside a tooth called the pulp. The pulp contains nerves and blood vessels that helped the tooth develop, but a fully grown adult tooth does not need the pulp to survive. Once the pulp is removed, cleaned, shaped, and sealed, the tooth can function normally for many years with a crown placed on top.
The term "root canal" actually refers to the natural hollow channel inside each tooth root where the pulp sits. There are typically one to four of these canals per tooth depending on the tooth type. Molars at the back of the mouth tend to have more canals than front teeth, which is part of why molar root canals take a bit longer to complete.
In practice, the procedure is performed under local anesthetic. The dentist creates a small access opening through the top of the tooth, uses specialized files to remove the pulp tissue, irrigates the canals thoroughly to eliminate bacteria, and then fills and seals the space with a rubber-like material called gutta-percha. The tooth is then restored, usually with a crown.
The Biggest Myths About Root Canals
The misinformation surrounding root canals is staggering, and it genuinely causes people to delay treatment until a minor infection becomes a dental emergency. Here are the myths that come up most often, and why the evidence does not support them.
Myth 1: Root Canals Are Extremely Painful
This is the most persistent myth, and it is rooted in what root canals used to involve decades ago before modern anesthetics and rotary instrumentation. According to the American Association of Endodontists, patients who have experienced root canal treatment are six times more likely to describe it as painless than those who have never had one. The pain people associate with root canals is the pain of the infection before treatment, not the treatment itself.
A common mistake is that patients wait until they are in severe pain before calling a dentist, then associate that pain with the upcoming procedure. The procedure is actually what ends the pain.
Myth 2: It Is Better to Just Pull the Tooth
Extraction seems simpler and cheaper upfront, but the long-term costs are significant. Removing a tooth without replacing it leads to bone loss in the jaw, shifting of surrounding teeth, bite problems, and an eventual need for an implant or bridge that costs considerably more than the root canal would have. Saving your natural tooth should always be the first priority, and root canal therapy is the primary tool for doing exactly that.
Myth 3: Root Canals Cause Illness
This myth traces back to debunked research from the early 1900s by Weston Price, who claimed that root-canaled teeth caused systemic disease. Major dental and medical organizations, including the Canadian Dental Association and the American Association of Endodontists, have thoroughly reviewed and dismissed this claim. There is no credible peer-reviewed evidence linking properly performed root canal therapy to any systemic disease.
"Decades of research and clinical evidence support the safety and efficacy of root canal treatment. Patients can be confident in choosing endodontic therapy to preserve their natural teeth." - American Association of Endodontists
Myth 4: If the Tooth Does Not Hurt, It Does Not Need Treatment
This one is dangerous. A tooth with a dead or dying pulp may stop hurting because the nerve tissue has been destroyed by the infection. The infection, however, continues to spread. Patients often present with large abscesses and bone loss around teeth they describe as completely pain-free. Diagnostic tools like X-rays and pulp vitality tests are how your dentist at Stavanger Dental identifies these silent infections before they become emergencies.
When Do You Actually Need a Root Canal?
Root canal therapy is indicated when the pulp of a tooth becomes irreversibly inflamed or infected. This happens through a specific set of circumstances, and recognizing them early gives you the best chance at a straightforward treatment rather than a complicated one.
Signs That Point to Pulp Involvement
Severe spontaneous toothache, pain that lingers for more than a few seconds after exposure to hot or cold, darkening of a tooth, swelling or tenderness in the gums near a tooth, and a persistent pimple-like bump on the gum are the most reliable warning signs. Not every case presents all of these, which is why routine dental visits that include bitewing X-rays are non-negotiable for catching problems early.
The causes of pulp infection typically include deep decay that has reached the pulp chamber, a cracked or fractured tooth that allows bacteria to penetrate, repeated dental procedures on the same tooth, or trauma to a tooth, even if the tooth looks intact from the outside. A front tooth that took a hard hit years ago during a hockey game can develop pulp death slowly and silently.
Pro tip: If you have a tooth that was sensitive to cold for weeks and then suddenly stopped being sensitive at all, do not assume it healed. That cessation of sensitivity can mean the pulp has died. Get it checked at Stavanger Dental before infection spreads to the surrounding bone.
The Modern Root Canal Procedure Step by Step
Understanding exactly what happens during the appointment removes the fear of the unknown, which is honestly where most dental anxiety lives. Here is what a painless root canal dentist appointment at a modern St. John's practice like Stavanger Dental looks like from start to finish.
Step 1: Diagnosis and Treatment Planning
Before anything else, a thorough clinical examination and X-ray assessment confirms the diagnosis. In some cases, a CBCT scan provides a three-dimensional view of the root canal anatomy, which is particularly useful for complex molar cases or teeth with unusual root curvature.
Step 2: Anesthesia Administration
Local anesthetic is administered to completely numb the tooth and surrounding tissue. For anxious patients, Stavanger Dental also offers sedation options, meaning there is no reason to white-knuckle through any part of this process. The dentist waits until the area is fully numb before beginning. This step is non-negotiable and nothing proceeds until you are comfortable.
Step 3: Access Opening and Pulp Removal
A rubber dam is placed around the tooth to keep it dry and free from saliva-borne bacteria. A small opening is made through the top of the tooth. Using a series of specialized rotary files, the dentist removes the pulp tissue from each canal, progressively shaping the canal to receive the filling material.
Step 4: Irrigation and Disinfection
The canals are irrigated repeatedly with antimicrobial solutions, typically sodium hypochlorite, to flush out bacteria, debris, and any remaining pulp tissue. This disinfection step is critical to the long-term success of the treatment and takes a significant portion of the appointment time.
Step 5: Obturation and Sealing
Once the canals are clean, dry, and shaped, they are filled with gutta-percha and sealed with a dental cement. A temporary or permanent filling closes the access opening. A crown is then fabricated and placed, typically at a follow-up appointment, to protect the treated tooth from fracture.
Comparing Your Treatment Options
When a tooth's pulp is infected or irreversibly inflamed, you realistically have three paths forward. Understanding the honest trade-offs of each helps you make an informed decision rather than a fear-based one.
Option
What It Involves
Long-Term Outcome
Root Canal Therapy followed by Crown
Pulp removal, canal cleaning and sealing, crown placement over one to two appointments
Tooth preserved; high success rate of 85 to 97 percent with proper restoration; no bone loss; maintains bite integrity
Tooth Extraction Only
Single appointment removal of the entire tooth under local anesthetic
Tooth lost permanently; surrounding teeth shift; jawbone resorbs; bite and aesthetics affected; requires replacement to avoid further problems
Extraction followed by Dental Implant
Tooth removed, bone healed, implant surgically placed, crown attached over several months
Excellent long-term result but significantly higher total cost and treatment time than root canal therapy; good option when the tooth cannot be saved
The data consistently shows that root canal therapy is the most cost-effective and biologically conservative option when a tooth is restorable. Extraction and implant is the right choice only when the tooth cannot structurally support a crown or when bone loss has made retention impossible.
Pro tip: Ask your Stavanger Dental provider directly whether your tooth is restorable before agreeing to an extraction. A second opinion is always your right, and a good dentist will support that decision rather than discourage it.
Recovery and What to Expect After Treatment
Recovery from a root canal is typically straightforward. Some mild soreness in the jaw and sensitivity around the treated tooth for two to three days after the appointment is normal, particularly if there was significant pre-existing infection or inflammation. Over-the-counter anti-inflammatories like ibuprofen manage this well in most cases.
You should avoid chewing hard foods on the treated tooth until the permanent crown is placed, since the tooth is temporarily more vulnerable to fracture without the protective restoration. Most patients return to normal eating and activity within 24 to 48 hours. If you experience escalating pain, swelling, or a reaction to the temporary filling that does not settle within a few days, contact Stavanger Dental promptly. These situations are uncommon but straightforward to address when caught early.
The success rate of root canal therapy, defined as the tooth remaining functional and symptom-free, is documented between 85 and 97 percent when the tooth is properly restored with a crown afterward. The most common reason for failure is not the endodontic treatment itself but the absence of proper coronal restoration following the procedure.
Root Canal Therapy and Sedation at Stavanger Dental
Stavanger Dental in St. John's is structured as a family dental office that manages the full spectrum of dental needs without sending patients to a rotating cast of specialists. That means root canal therapy NL patients can receive their treatment in a familiar environment with a team that already knows their dental history and anxiety profile.
For patients with significant dental anxiety, sedation options are available. Sedation dentistry does not mean being unconscious. Options range from nitrous oxide, which creates a relaxed and calm state while you remain fully awake and responsive, to oral sedation for deeper relaxation. This is particularly valuable for patients whose fear of the procedure has caused them to delay treatment until the infection has become severe.
Stavanger Dental also accepts the Canadian Dental Care Plan. For eligible patients, this significantly reduces the out-of-pocket cost of endodontic treatment, which is a real barrier for many families in Newfoundland. Checking your eligibility before your appointment is a practical first step that the Stavanger Dental team can help walk you through.
The practice takes emergency appointments, which is directly relevant for root canal situations. Dental infections do not follow a Monday-to-Friday schedule, and severe toothache or swelling near a tooth needs prompt clinical assessment. Patients in St. John's with acute symptoms should not wait out a long referral queue to see the treatment addressed.
Frequently Asked Questions
How long does a root canal procedure take at a St. John's dental office?
Most root canal procedures at Stavanger Dental are completed in one to two appointments. A single-rooted tooth like a front incisor can often be treated in about 60 minutes. A molar with three or four canals may require 90 minutes or occasionally a second appointment to complete disinfection and obturation. Complex cases or teeth with very curved root anatomy take longer, but your dentist will give you a realistic time estimate after reviewing your X-rays.
Is a root canal more painful than a tooth extraction?
Research consistently shows that patients rate root canal therapy as comparable to or more comfortable than a simple tooth extraction. Both are performed under local anesthetic. The key difference is that a root canal preserves the tooth while an extraction removes it, requiring additional future treatment to address the gap. Pain after a root canal is typically mild and managed with over-the-counter medication, similar to post-extraction soreness.
Will my tooth look different after root canal therapy?
The tooth itself may darken slightly over time after the pulp is removed, particularly front teeth. However, this is addressed with tooth-coloured crowns or, in some front tooth cases, internal bleaching. Stavanger Dental offers cosmetic options including veneers and crowns that match surrounding teeth, so the final result is both functional and aesthetically natural.
Can root canal therapy fail, and what happens if it does?
Root canal therapy can fail, though it is uncommon when the tooth is properly restored afterward. Failure usually presents as a return of symptoms, a persistent lesion visible on X-ray, or a new infection. In these cases, endodontic retreatment, where the canals are reopened, cleaned again, and resealed, is the standard next step. The success rate of retreatment is somewhat lower than initial treatment but still clinically meaningful. Extraction becomes the option only when retreatment is not feasible.
Does the Canadian Dental Care Plan cover root canal therapy?
The Canadian Dental Care Plan covers a range of dental procedures for eligible Canadians, and endodontic treatments including root canal therapy are included for eligible patients. Coverage specifics depend on the tooth involved, the number of canals, and your eligibility tier. Stavanger Dental accepts the Canadian Dental Care Plan, and the administrative team can help you understand what is covered for your specific case before you commit to treatment.
How do I know if I need a root canal or just a filling?
A filling is appropriate when decay has not reached the pulp chamber. If decay or a fracture has allowed bacteria to reach the pulp, or if the pulp has become infected through other means, a filling alone will not resolve the problem. Your dentist determines this through clinical examination, symptom assessment, and X-ray analysis. If you are experiencing spontaneous tooth pain, sensitivity that lingers for more than a few seconds, or swelling near a tooth, have it assessed promptly. Early detection almost always means a simpler, less invasive treatment path.
