A root canal is one of the most common dental procedures, yet many patients—and even some dentists—have questions about why it’s needed, how it works, and what recovery looks like. If you’re a dentist in North America, understanding these details helps you educate patients and improve case acceptance.
We’ll also discuss related treatments, such as pulpotomy vs. pulpectomy, and key factors affecting tooth canal cost and recovery.
What Is a Root Canal?
A root canal is a dental procedure that removes infected or damaged pulp inside a tooth, cleans the tooth canals, and seals them to prevent reinfection. This treatment saves natural teeth and avoids extraction. We need dental root or tooth canal for this treatment
Common reasons for needing a tooth canal include:
- Deep decay (untreated cavities reaching the pulp)
- Cracked or chipped teeth (exposing the pulp)
- Trauma (impact injuries damaging the nerve)
- Repeated dental procedures (weakening the tooth)
The infection can spread if left untreated, leading to abscesses, bone loss, or systemic issues.
Is a Root Canal Considered Surgery?
While a root or tooth canal is a minimally invasive procedure, it’s technically endodontic therapy, not traditional surgery. Unlike extractions or implants, it preserves the natural tooth structure.
However, a surgical approach may be needed in complex cases (like retreatment or apicoectomy). Most standard tooth canals are performed in-office with local anaesthesia.
Pulpectomy vs. Root Canal
Patients (and even some dentists) often confuse pulpectomy with a root or tooth canal. Here’s the breakdown:
- Purpose
- Pulpectomy: Removes all pulp tissue (both coronal and radicular) to eliminate infection in primary or severely damaged permanent teeth.
- Tooth Canal: Focuses on cleaning, shaping, and sealing the canals after pulp removal to preserve the natural tooth structure in permanent teeth.
- Common Use Cases
- Pulpectomy: Preferred for baby teeth with irreversible pulpitis or abscesses or as a temporary measure in young permanent teeth.
- Tooth Canal: Standard treatment for infected permanent teeth with necrotic pulp or irreversible inflammation.
- Procedure Steps
- Pulpectomy:
- Extirpates entire pulp (chamber + canals).
- Fills canals with resorbable material (e.g., zinc oxide-eugenol) for primary teeth.
- Tooth Canal:
- Uses files and irrigants to clean/shape canals.
- Obturates with gutta-percha and permanent sealer.
- Pulpectomy:
- Material Differences
- Pulpectomy: Uses biocompatible, resorbable fillers (to avoid interfering with permanent tooth eruption).
- Tooth Canal: Requires non-resorbable materials (gutta-percha) for long-term sealing.
- Outcome & Follow-Up
- Pulpectomy: Buys time until primary tooth exfoliates; no crown typically needed.
- Tooth Canal: Requires final restoration (crown) to prevent fracture in permanent teeth.
- Pain & Recovery
- Both procedures are low-pain with modern anaesthesia.
- Pulpectomy recovery is faster (no crown placement needed).
Conversely, a pulpotomy removes only the coronal pulp, leaving the roots intact (common in baby teeth).
How Long Does a Root Canal Take?
A typical root or tooth canal takes 60-90 minutes, but complex cases (molars, curved canals) may require two visits. Factors affecting duration include:
- Tooth location (front teeth are faster)
- Infection severity (abscesses need drainage)
- Number of canals (molars have 3-4 canals)
Patients often ask, “How much is a dental filling canal?“ Costs range from $700-$1,500 (depending on tooth type, location, and specialist involvement).
Root Canal Recovery
Most patients recover within a few days. Here’s what to advise:
- Mild discomfort (manageable with OTC painkillers)
- Avoid chewing on the treated tooth until it is fully restored
- Follow-up crown placement (essential for long-term success)
If pain persists beyond a week, retreatment or further evaluation may be needed.
Final Thoughts
A root or tooth canal is a highly effective way to save infected teeth by dental root canal. While pulpectomy and pulpotomy serve different purposes, understanding when to recommend each ensures better patient outcomes.
For dentists in North America, educating patients on tooth canal treatment, recovery, and cost improves case acceptance and trust.

FAQ’s:
What is a root canal?
A root or tooth canal is a dental procedure that removes infected or damaged pulp inside a tooth. It cleans and seals the canals to prevent infection while saving the natural tooth.
How long does a root canal take?
A standard tooth canal takes 60-90 minutes, but complex cases (like molars) may require two visits. The duration depends on tooth location and infection severity.
How much is a root canal?
A root or tooth canal costs $700 to $1,500, depending on the tooth and the dentist’s expertise. Molars and specialists typically cost more than front teeth.
Do root canals hurt?
Modern anaesthesia ensures tooth canals are not painful. Patients may feel mild pressure, but severe pain is rare. Discomfort after the procedure is usually manageable with OTC painkillers.
Are root canals bad for you?
No, tooth canals are safe and effective for saving infected teeth. They prevent tooth loss and stop infections from spreading to other body parts.
Are root canals painful?
With proper anaesthesia, most patients report minimal pain during the procedure. Post-treatment soreness is normal but fades within a few days with appropriate care.
What causes a root canal?
Deep decay, cracks, trauma, or repeated dental work can damage the tooth pulp, leading to infection. Without treatment, this can cause abscesses or bone loss.
Can a root canal raise body temperature?
A severe tooth infection before treatment may cause fever, but the tooth canal does not raise body temperature. Proper treatment eliminates the infection and reduces systemic risks.
