Root canal treatment has a disproportionate reputation for pain — a reputation built almost entirely on how the procedure felt decades ago, before modern anaesthesia, nickel-titanium rotary instrumentation, and apex locators changed the clinical reality. The procedure itself is not painful when performed properly. The infection it treats is painful. The root canal relieves that pain; it does not create it.
At Dazzle Dental Clinic, root canal treatment (endodontic therapy) is performed by experienced clinicians using rotary NiTi instrumentation, sodium hypochlorite irrigation, and electronic apex locators — the current standard of care. Sedation options are available for anxious patients.
What the Procedure Involves
When bacteria penetrate through a cavity, crack, or failing restoration into the pulp — the nerve and blood supply inside the tooth — infection develops. Root canal treatment removes the infected pulp (pulpectomy), shapes the canal system with rotary NiTi files, irrigates with sodium hypochlorite, applies an intracanal medicament (calcium hydroxide) between appointments where indicated, and obturates the cleaned canal with gutta-percha and a biocompatible sealer. The access cavity is sealed with a durable restorative material or a post-core if tooth structure is insufficient. Following obturation, a crown is recommended for posterior teeth to protect against fracture.
Why It Is Not Painful
Adequate local anaesthesia is the key variable. Inflamed tissue has a lower pH, which can reduce the efficacy of conventional inferior alveolar nerve block — known as hot tooth anaesthesia failure. At Dazzle, supplemental techniques (intraligamentary injection, intrapulpal injection) are used when standard block does not achieve full anaesthesia. The rule: the procedure does not proceed if the patient is feeling pain. Additional anaesthesia is administered until the tooth is fully numb.
For patients with dental anxiety, nitrous oxide (conscious sedation) or oral sedatives can be added alongside local anaesthesia. IV sedation is available for patients who prefer to be unaware of the procedure entirely. For a detailed overview of sedation options, see our sedation safety guide.
Number of Appointments and Timeline
Single-rooted teeth (incisors, canines) with straightforward anatomy and no acute abscess: typically one appointment, 60–90 minutes. Multi-rooted posterior teeth (molars, premolars) with complex anatomy or active acute infection: two appointments. First appointment: pulpectomy and calcium hydroxide dressing. Second appointment (1–2 weeks later): obturation and restoration planning. Crown preparation and delivery: separate appointment(s) at Dazzle’s in-house laboratory, typically within 1–3 weeks of canal obturation.
When Root Canal Treatment Is and Is Not the Right Decision
Root canal treatment is appropriate when: the tooth has a restorable crown structure; the root is sound without untreatable vertical fracture; and the periapical pathology is the primary cause of symptoms. It is the treatment that saves the tooth.
It is not always the right decision. A tooth with a vertical root fracture extending below the bone level cannot be saved by root canal treatment. A tooth with less than 1.5–2mm of sound dentine for ferrule effect cannot support a crown regardless of endodontic status. A tooth with advanced bone loss from periodontitis has a poor long-term prognosis regardless of the endodontic outcome. In these situations, extraction and implant replacement produces a more predictable long-term result. At Dazzle, the assessment is honest about prognosis.

FAQs
Q1: What is a root canal retreatment and when is it needed?
If a previously root canal treated tooth develops new or persistent periapical infection, retreatment involves reopening the canal, removing the old gutta-percha, re-cleaning and re-obturating. Published healing rates at 2–4 years: 70–85% periapical resolution — lower than initial treatment (90–95%) but still the preferred option over extraction in most cases. If retreatment fails, apicoectomy (surgical root-end resection) is the next option.
Q2: Will the tooth be discoloured after root canal treatment?
Tooth discolouration after root canal treatment is caused by blood breakdown products left in the pulp chamber. Modern endodontic protocols include thorough pulp chamber irrigation to minimise this. If discolouration occurs, internal bleaching or a ceramic crown can address the shade change.
Q3: How long does a root canal treated tooth last?
Published 10-year survival rates for root canal treated and crowned posterior teeth: approximately 80–90%. The crown quality, occlusal load, and oral hygiene maintenance are the primary determinants. A properly treated and crowned tooth can function for the patient’s lifetime in many cases.
Q4: What if I choose not to have root canal treatment?
The infection will not resolve without treatment. Options: root canal treatment (saves the tooth), or extraction. Without either, the infection progresses — potentially to facial swelling, bone destruction, and systemic spread in severe cases. Delaying the decision does not create a third option; it narrows the choices and may make eventual extraction more complex.
