Pain & emergency
Root canal therapy — save a tooth from the inside.
When decay or trauma reaches the nerve, root canal treatment is what saves the tooth. Modern techniques mean it's far more comfortable than its reputation. Single-canal cases happen here; complex cases go to a specialist we work with.
What root canal therapy is
Inside every tooth is a soft tissue called the pulp — nerves, blood vessels, connective tissue. When decay reaches the pulp, or a tooth is cracked deeply, the pulp becomes inflamed or infected. Untreated, this leads to constant pain, abscess, and eventually losing the tooth.
Root canal therapy (sometimes shortened to RCT or endodontic treatment) removes the infected pulp, cleans and shapes the canals inside the roots, and seals them. The tooth itself stays — it's the inside of the tooth that's treated. After RCT, the tooth is usually restored with a crown to protect what's left of the structure.
How we work — single-canal in-house, complex referred
Oracare does single-canal root canals on anterior and bicuspid teeth (front teeth and the small teeth just behind them) in-house. This is the scope we handle here day to day; Dr Thao has performed these cases throughout her 20+ years of practice. Some straightforward molar cases may also be treated here when imaging shows accessible canals.
For complex cases — most molar root canals (multi-canal with difficult curvature), calcified canals that won't accept instruments, broken-instrument retrieval, and retreatment of failed prior RCT — we refer to Camp Hill Specialist Centre. The endodontists there focus exclusively on root canal work and have specialist equipment (operating microscopes, CBCT-guided navigation) that we don't have in general practice.
We make the in-house vs refer call at the consultation, based on the X-ray and clinical exam. If you're in pain right now, we can stabilise the tooth (pain relief, sometimes opening the pulp chamber to release pressure) at the first visit before any decision on who does the definitive treatment.
What to expect — in-house single-canal
-
Visit 1
Consultation + pain relief. We take an X-ray, examine the tooth, and discuss findings. If you're in active pain, we can start treatment at this visit — opening the pulp chamber under local anaesthetic, removing the inflamed tissue, and dressing the canal with antibacterial medication. You leave with the pain settling.
-
Visit 2
Canal cleaning and shaping. Under local anaesthetic, we fully clean and shape the canal — removing all infected tissue, irrigating with antibacterial solution. The canal is then sealed with a biocompatible filling material called gutta-percha, and the access cavity in the top of the tooth is closed with a temporary or interim filling.
-
Follow-up
Crown or final restoration. Root-canal-treated teeth become more brittle over time without their internal blood supply. For most cases we recommend a crown within a few months to protect the tooth from fracture. We'll plan this with you at the end of treatment.
Some single-canal cases can be completed in one visit if you're not in active infection at the start. Multi-canal molar cases — when referred to the specialist — typically run 1–2 longer appointments at the specialist's clinic.
Common questions
Does it hurt?
The reputation that root canals are painful is decades out of date. The pain that brings most patients in — from infected pulp pressing on the nerve — is usually the worst part; in most cases, treatment addresses that pain once the infection is removed. Local anaesthetic is standard throughout the procedure, and most patients describe the experience as comparable to having a deep filling: pressure rather than sharp pain. Mild soreness for a few days afterwards is normal and settles with over-the-counter pain relief.
Why not just pull the tooth instead?
Extracting a tooth is faster and usually cheaper up front — but it leaves a gap. Gaps allow neighbouring teeth to drift, change your bite, and over time put pressure on the rest of your dentition. Keeping your own tooth is often the preferred outcome when the tooth can be saved — root canal is one way to do that. Replacing a missing tooth later (with an implant, bridge or partial denture) can cost more overall than saving the tooth, depending on the replacement option and your situation.
How long does the treatment take?
Single-canal cases at Oracare typically take 1–2 visits of 60–90 minutes each. Multi-canal molar cases referred to the specialist usually take 1–2 longer appointments at their clinic. Either way, we aim to settle pain at the first visit if you're in active discomfort.
Will I need a crown after?
For most root-canal-treated teeth — particularly molars and premolars that take heavy bite force — yes. Without their internal blood supply, treated teeth become more brittle and prone to fracture. A crown protects the tooth and is typically fitted within a few months of completing the RCT. Some front-tooth single-canal cases can be restored with a filling instead of a crown — we'll advise based on how much tooth structure is left.
When would you refer me to a specialist?
We refer when the case is outside what's safely done in general practice — most molar root canals (multiple canals with curvature), calcified canals that won't accept instruments, broken-instrument retrieval, or retreatment of a previously-failed RCT. Camp Hill Specialist Centre handles our referrals; they focus exclusively on endodontic work with specialist equipment we don't have in general practice. We make the call at consultation based on the X-ray.
What if the root canal fails?
Root canal failure is uncommon but possible — usually from re-infection, a missed canal, or fracture of the tooth structure. If failure looks likely (persistent pain, X-ray changes), we'd refer to the specialist for assessment. Options include retreatment, endodontic surgery (if appropriate), or — if the tooth is no longer salvageable — extraction with a bridge or implant plan.
Will my health fund cover it?
Most extras policies rebate part of root canal treatment because it's a clinically-driven (not cosmetic) procedure. The portion covered depends on your fund, level of cover, and whether the case is single- or multi-canal. We claim through HICAPS at the chair so you only pay the gap. If your case is referred to the specialist, the specialist bills you and their clinic; we coordinate the case but the financial relationship is between you and them at that point. See Payment options.
Cost & funding
HICAPS on the spot. Health funds typically rebate part of root canal treatment. We claim at the chair — you only pay the gap. Interest-free in-house payment plans are available for larger plans. If your case is referred to a specialist, their fee is billed and paid directly to their clinic. Full detail on Payment options.
