Smile Solutions: The Root Canal Procedure Step by Step — What Happens During Endodontic Treatment

Most patients arrive at a specialist endodontic practice carrying some version of the same worry: they know they need a root canal, but they have no clear picture of what will actually happen to them in the chair. That uncertainty, more than any specific dread of pain, is usually what drives the anxiety. When you understand what a specialist endodontist does at each stage, and why they do it, the procedure stops feeling vaguely threatening and becomes what it actually is: a logical, highly controlled sequence of clinical steps with one goal — saving your natural tooth.

Smile Solutions is Melbourne's specialist dental destination, and this guide walks you through exactly what happens during a root canal appointment at a specialist endodontic practice like Smile Solutions Melbourne. It covers every stage from your first diagnostic examination through to the placement of a temporary restoration, explaining the clinical rationale behind each step, the sensations you can expect, and how specialist-grade technique and current technology make each phase more precise and more comfortable than what was possible even a decade ago.

What Is a Root Canal, Clinically Speaking?

Before the steps, the concept.

Root canal therapy (RCT) removes infectious agents, treats the disease, and preserves natural teeth. More specifically, a root canal removes infected pulp from inside your tooth, after which the dentist cleans and seals the canals to prevent further damage and save the tooth.

The primary objective of endodontic treatment is to preserve the natural dentition through the prevention and treatment of pulpal and periradicular pathosis. Every step in the procedure below serves that objective, and at Smile Solutions, every step is carried out with that goal firmly in focus.

How Long Does a Root Canal Take? A Quick Reference

Before diving into the steps, it helps to anchor your expectations around time. The answer depends primarily on which tooth is being treated and how many canals it contains.

In most cases, a root canal takes 60 to 90 minutes to complete. Some straightforward cases wrap up in a single visit, while more complex situations may require two or more appointments. Endodontists are often able to complete treatment in one visit, but anatomy, infections, or calcifications can make two appointments the better clinical choice.

Specialist endodontists generally complete cases more quickly than general dentists, particularly on difficult or complex teeth, and at Smile Solutions our experienced specialists are equipped with the technology and training to do exactly that.

Stage 1: Pre-Treatment Examination and Diagnosis

What the endodontist assesses before touching the tooth

Your appointment begins before any instrument enters your mouth. At a specialist practice, the diagnostic phase is thorough and methodical, because every subsequent decision depends on an accurate understanding of your tooth's anatomy, the extent of infection, and the case's complexity.

The Australian Society of Endodontology (ASE) identifies diagnosis and case difficulty assessment as foundational to what a competent practitioner does before commencing treatment. At Smile Solutions, this assessment includes:

• Clinical examination: percussion testing (tapping the tooth), palpation of surrounding gum tissue, probing for periodontal involvement, and pulp vitality testing using cold or electric stimulation
• Periapical radiographs: two-dimensional images taken at different angles to assess root length, canal curvature, periapical bone status, and existing restorations
• Cone Beam CT (CBCT) imaging where indicated: three-dimensional imaging that reveals anatomy invisible on conventional X-rays, including extra canals, root fractures, and the precise extent of periapical pathology

With CBCT, clinicians gain a clearer understanding of root canal anatomy and the technique sensitivity of root canal therapy, which contributes directly to treatment efficacy.

Your endodontist will assign a formal diagnosis, for example symptomatic irreversible pulpitis or pulp necrosis with symptomatic apical periodontitis, and explain the personalised treatment plan, the expected number of appointments, and what you will experience at each stage. (For a full explanation of the symptoms that lead to this appointment, see our guide on Signs You Need a Root Canal: Symptoms, Causes, and When to See a Specialist.)

Stage 2: Local Anaesthesia — Achieving Profound Numbness

What you will feel (and what you won't)

Once the diagnosis is confirmed and treatment is consented, the first clinical act is anaesthesia. This stage is the single most important determinant of your comfort, and it is where specialist technique diverges most clearly from routine general dental practice.

Your endodontist administers a local anaesthetic, most commonly lignocaine (lidocaine) with adrenaline, via inferior alveolar nerve block for lower teeth or infiltration for upper teeth. The injection itself involves a brief sting as the needle enters the soft tissue; the anaesthetic is then deposited slowly to minimise discomfort.

For teeth with hot pulpitis (active, inflamed pulps that are notoriously difficult to numb), a specialist endodontist has access to supplemental techniques including:

• Intraligamentary (periodontal ligament) injection: anaesthetic delivered directly into the space between the tooth root and bone
• Intraosseous injection: anaesthetic delivered directly into the surrounding bone
• Intrapulpal injection: a small volume of anaesthetic deposited directly into the pulp chamber once access is established

Because they are performed under local anaesthesia, root canals are generally no more painful than other routine dental procedures. The goal at Smile Solutions is complete, verified anaesthesia before any instrumentation begins. (For a comprehensive discussion of pain science and anaesthesia protocols, see our guide on Root Canal Pain and Anaesthesia: Does Root Canal Treatment Hurt in 2025?)

Stage 3: Rubber Dam Placement — Isolating the Operative Field

A non-negotiable safety and quality step

Once your tooth is numb, the endodontist places a rubber dam, a thin sheet of latex or latex-free material that isolates the tooth being treated from the rest of your oral cavity.

To keep the area clean and free of saliva, the dentist places a small protective sheet called a dental dam around the tooth, which keeps the area isolated and dry throughout the procedure.

The rubber dam serves multiple critical functions:

• Infection control: prevents oral bacteria from contaminating the sterile canal system during treatment
• Airway protection: prevents small instruments, irrigants, and debris from being swallowed or inhaled
• Moisture control: keeps the tooth dry, which is essential for irrigant efficacy and material adhesion
• Visibility: retracts soft tissue and provides a clean operative field

Rubber dam use is a standard of care in specialist endodontics. The ASE's 2024 guidelines for non-surgical root canal treatment identify isolation as a core competency requirement, and at Smile Solutions, it is a step we never skip.

Stage 4: Access Cavity Preparation — Opening the Tooth

Creating the gateway to the canal system

With your tooth isolated, the endodontist uses a high-speed dental drill to create an opening through the crown of the tooth, through enamel and dentine, into the pulp chamber below. The dentist removes the decay and makes an opening through the crown to reach the pulp chamber.

The design of this access cavity is more considered than it appears. Modern specialist practice favours a conservative (ninja/truss) access design that preserves as much tooth structure as possible while still allowing straight-line access to all canal orifices. Under the operating microscope, standard equipment at Smile Solutions, your endodontist can precisely locate every canal opening in the pulp chamber floor, including additional canals that are easily missed without magnification.

Over the past two decades, significant advances in technology and materials have shaped endodontic practice, including the operating microscope, engine-driven nickel-titanium instruments, ultrasonics, enhanced irrigation technologies, digital radiography, cone-beam computed tomography, and calcium silicate (bioceramic) materials.

You will feel pressure and vibration during this stage but no sharp pain. If you feel anything uncomfortable, simply raise your hand and your endodontist will administer supplemental anaesthesia straight away.

Stage 5: Working Length Determination — Mapping the Canal

Precision measurement before instrumentation

Before any shaping begins, your endodontist must determine the precise length of each canal, specifically the working length, which is the distance from a reference point on the crown to a point 0.5–1.0 mm short of the anatomical apex (root tip).

This is achieved using an electronic apex locator, a device that measures the electrical resistance between the file tip and the periodontal ligament, providing a real-time reading of file position within the canal. This measurement is confirmed with a periapical radiograph.

Specialist practices use a computerised drill with an electronic apex locator that gives a precise location for the end of the root, and torque sensing that automatically adjusts the rotation of the super-elastic files to ensure precise, safe, and efficient shaping. This improves both treatment effectiveness and safety while reducing chair time.

Accurate working length determination is non-negotiable: over-instrumentation risks damaging the periapical tissues; under-instrumentation leaves infected tissue in the apical portion of the canal, one of the primary causes of treatment failure. (For more on failure causes, see our guide on Root Canal Retreatment: When and Why a Previous Root Canal Fails and How Specialists Fix It.)

Stage 6: Canal Shaping — Mechanical Debridement with Rotary Files

Removing infected tissue and preparing the canal for filling

This is the mechanical core of the procedure. Your endodontist uses a series of nickel-titanium (NiTi) rotary files, flexible, tapered instruments driven by a motor-controlled handpiece, to progressively enlarge and shape each canal from its orifice to its working length.

The goals of shaping are threefold:

1. Debridement: physical removal of infected pulp tissue, bacteria, and necrotic material
2. Shaping: creating a smooth, tapered canal form that allows irrigants to penetrate the full length of the canal and facilitates complete obturation
3. Patency: maintaining the natural curvature of the canal while ensuring the apical foramen remains unblocked

Common endodontic treatment concepts are based on removing inflamed or necrotic pulp tissue and replacing it with gutta-percha; however, thorough debridement of the root canal system and prevention of bacterial reinfection after treatment are equally essential to success.

NiTi rotary files are significantly more flexible than older stainless-steel instruments, allowing them to negotiate curved canals without straightening them, a critical advantage in molars with complex anatomy. The degree of bacterial infection, the root canal anatomy, the instruments chosen, and the treatment techniques employed are all closely tied to treatment outcomes.

During this stage, you will feel vibration and some pressure but no sharp pain. The procedure is systematic: files are used in a sequence, either crown-down or smaller to larger depending on the protocol, with copious irrigation between each instrument change.

Stage 7: Irrigation and Disinfection — The Chemical Dimension of Cleaning

Why this stage matters as much as the mechanical shaping

Mechanical shaping alone cannot sterilise a root canal system. The complex internal anatomy of teeth, including lateral canals, fins, isthmuses, and dentinal tubules, harbours bacteria that files cannot physically reach. Chemical irrigation addresses this reality, and it is a stage your Smile Solutions endodontist approaches with the same rigour as every other.

Sodium hypochlorite (household bleach) is the most commonly used root canal irrigant; it is an antiseptic and inexpensive lubricant used in dilutions ranging from 0.5% to 5.25%. NaOCl has excellent antimicrobial properties and dissolves vital or necrotic tissues effectively, while EDTA is used as an adjuvant to remove the smear layer.

The standard irrigation protocol at a specialist practice involves:

• Sodium hypochlorite (NaOCl): delivered throughout shaping to dissolve organic tissue and kill bacteria
• EDTA (ethylenediaminetetraacetic acid): a chelating agent used in the final irrigation sequence to remove the smear layer, a film of debris that coats the canal walls after instrumentation and can harbour bacteria
• Ultrasonic or sonic activation: agitation of the irrigant using ultrasonic tips or sonic devices to drive the solution into anatomical spaces that passive syringe irrigation cannot reach

Both irrigants showed considerable antimicrobial effect, but NaOCl achieved a 96% reduction in bacterial load, compared to alternative irrigants' 86% (Prasad et al., Journal of Pharmacy and Bioallied Sciences, 2025). Research published in the Journal of Endodontics (Silva et al., 2025) found that an extended protocol of NaOCl contact time with periodic renewal produced significantly greater microbial reduction compared with standard continuous irrigation.

Successful endodontic treatment requires debridement through mechanical instrumentation and chemical disinfection followed by sealing with appropriate materials; irrigation is essential because it cleans irregularly shaped canals and isthmuses that instruments cannot reach.

Specialist endodontists at Smile Solutions calibrate their NaOCl concentration carefully. Research published in the International Endodontic Journal (Xu et al., 2022) confirmed that higher NaOCl concentrations have greater effects on dentine structure; endodontists should follow the principles of minimally invasive dentistry and avoid unnecessarily high concentrations, as this helps prevent root fracture after treatment.

This evidence-based, calibrated approach to irrigation is what distinguishes specialist endodontic care from general dental practice. (For a detailed breakdown of the technology used during irrigation and shaping, see our guide on Root Canal Technology at Smile Solutions: Cone Beam CT, Rotary Instrumentation, and Dental Microscopes.)

Stage 8: Intracanal Medication (If a Second Appointment Is Needed)

When the endodontist decides to defer obturation

In cases involving severe infection, large periapical abscesses, or persistent bacterial contamination, your endodontist may place an intracanal medicament, most commonly calcium hydroxide (Ca(OH)₂), and defer obturation to a second appointment, typically one to four weeks later.

Intracanal medicaments are used to disinfect root canals between appointments and reduce interappointment pain; calcium hydroxide remains the most widely used option in current endodontic practice.

A temporary restoration seals the access cavity between appointments. If this applies to your treatment, it is not a sign that anything has gone wrong. It is a deliberate clinical decision to optimise the disinfection environment before permanent obturation, and your endodontist will explain exactly why it is the right approach for your situation.

Stage 9: Obturation — Filling and Sealing the Canal System

The step that locks in the result

Once the canals are clean, shaped, and dry, your endodontist obturates, filling and sealing the prepared canal system. The goal is a three-dimensional, hermetic seal that prevents recontamination from residual bacteria and blocks fluid ingress from the coronal direction.

The standard obturation material is gutta-percha, a natural rubber-like material available in standardised tapered cones, used alongside a root canal sealer. Modern specialist practices increasingly use bioceramic (calcium silicate-based) sealers, which offer excellent biocompatibility, dimensional stability, and chemical bonding to dentinal walls.

Warm gutta-percha technique combined with a bioceramic sealer produces high success rates in endodontically treated teeth. A 2024 systematic review and meta-analysis by Zamparini et al., published in the International Endodontic Journal, found that studies comparing bioceramic versus standard sealers reported similar outcomes for tooth survival, treatment outcome, post-operative pain, and periapical extrusion, with no significant differences between the two sealer types.

Common obturation techniques include:

• Warm vertical compaction (continuous wave): gutta-percha is heated and compacted vertically, flowing into lateral canals and anatomical complexities
• Cold lateral condensation: a master cone is placed to length and accessory cones are compacted laterally alongside it
• Single-cone with bioceramic sealer: a single matched cone is placed to working length with a hydraulic bioceramic sealer filling the remaining space

A post-obturation radiograph is taken immediately to confirm the quality of the fill, verifying that the obturation reaches the correct working length with no voids. This final quality check is part of the care you can expect at every Smile Solutions appointment.

Stage 10: Coronal Restoration — Sealing the Access Cavity

The final step in the chair that day

Your endodontist places a temporary restoration, typically a glass ionomer cement or composite, to seal the access cavity before you leave. This prevents coronal leakage: the ingress of oral bacteria through the crown that can recontaminate the now-clean canal system.

Patients should contact their dentist to arrange an appointment one to two weeks after endodontic treatment is complete, as the tooth can become reinfected or otherwise compromised without a timely restoration.

The temporary restoration is not the final step in your care. Within weeks, you will return to your referring dentist for a permanent restoration, in most cases a dental crown, which protects the structurally compromised tooth from fracture and ensures long-term survival. Your Smile Solutions endodontist will give you clear guidance on next steps before you leave the practice. (For guidance on this critical phase, see our guide on Root Canal Aftercare: Recovery Timeline, Restrictions, and Long-Term Tooth Survival.)

What You Will Experience During and After the Procedure

Sensations during treatment

• Pressure and vibration: normal throughout shaping and obturation
• Intermittent sounds: the rotary handpiece and ultrasonic devices produce noise; this is entirely expected
• A sensation of movement: particularly during working length measurement and obturation
• No sharp pain: if you feel sharp pain at any point, raise your hand and your endodontist will administer additional anaesthesia straight away

Post-procedure sensations

Some soreness, numbness, or mild discomfort may persist for 24–48 hours after treatment, which over-the-counter pain medications can usually manage, and nearly all patients return to normal activities the same day. For a few days you may notice sensitivity, so avoid chewing directly on the treated tooth until this resolves; after three to seven days, that sensitivity is usually gone.

Your Smile Solutions care team is always available to answer questions or address any concerns during your recovery.

Key Takeaways

• Root canal treatment is a multi-stage procedure, not a single act. Each stage, from diagnosis and anaesthesia through isolation, access, shaping, irrigation, obturation, and temporary restoration, serves a specific clinical purpose and must be executed in sequence.
• Appointment duration varies by tooth type: anterior teeth typically require 45–60 minutes; molars with three or four canals may require 90 minutes or more, sometimes across two visits.
• Irrigation is as important as mechanical shaping. Sodium hypochlorite achieves up to a 96% reduction in bacterial load and dissolves organic tissue that instruments cannot reach; EDTA removes the smear layer to optimise the seal.
• Modern specialist technique is minimally invasive: conservative access cavity design, NiTi rotary files, electronic apex locators, and operating microscopes preserve tooth structure while achieving superior canal cleanliness.
• Obturation is not the end of treatment. A timely permanent restoration, placed by your referring dentist within weeks, is essential to protect your tooth and ensure long-term success.

Conclusion

Understanding the root canal procedure step by step removes the most common source of patient anxiety: the unknown. What you are facing is a logical, well-sequenced clinical protocol, carried out by a specialist with years of advanced training, using instruments and materials specifically designed for this purpose.
