Root Canal Treatment in Mount Lawley

Relieving severe toothache and saving natural teeth — with sedation options available for patients who find dental treatment difficult.

Root canal treatment relieves pain — it doesn't cause it

Inside every tooth is a soft core of nerve tissue and blood vessels called the pulp. When deep decay, a crack or a heavy knock allows bacteria to reach that pulp, it becomes inflamed and then infected — and because the pulp is sealed inside a rigid chamber, the pressure has nowhere to go. That is what produces the deep, throbbing, keeps-you-awake toothache people describe. Root canal treatment removes the infected tissue, disinfects and seals the canal system, and allows you to keep a tooth that would otherwise have to come out.

The old reputation of root canals belongs to a different era of dentistry. Today the procedure is done under profound local anaesthetic, and the honest experience for most patients is that it feels much like having a large filling — with the enormous relief of the pain finally stopping. What people remember as agonising is almost always the infected tooth beforehand, not the treatment itself. At Dental On Railway we also offer Penthrox inhaled sedation and, through a visiting anaesthetist, twilight IV sedation — an option that is rare in the Mount Lawley area and genuinely transformative for anxious patients.

Dr Simon Frame brings over twenty years of clinical experience and digital imaging to every case, so you can see exactly what's happening inside your tooth. Nothing about your care is rushed, and you'll see the same dentist from diagnosis through to the final crown. Free parking sits directly across Railway Parade and ACROD accessible parking is at our front door.

What We Offer

Treatments & what to expect

Click any treatment to see the step-by-step process we'll take you through.

Root Canal Therapy

The complete procedure to remove infected pulp, clean and shape the canal system, and seal the tooth so it can stay in function for many more years.

Emergency Pain Relief

If you're in acute pain we can often open and drain the tooth on the day, releasing pressure and settling the infection so you can sleep, with the full treatment completed at a planned appointment.

Re-Treatment of Failed Root Canals

Occasionally a previously treated tooth becomes symptomatic again. We can remove the old filling material, re-clean the canal system and re-seal it, or refer to an endodontist for complex cases.

Crowns After Root Canal

A custom crown restores full chewing strength and protects the tooth from fracture. We use digital scanning for a precise fit and shade-matched ceramics for a natural result.

Sedation for Root Canal Treatment

Penthrox inhaled sedation for rapid relaxation, or twilight IV sedation with a visiting anaesthetist for patients with significant dental anxiety — a rare offering locally.

Cracked Tooth Assessment

Pain on biting and release often signals a crack rather than decay. We diagnose the extent of the crack and advise whether a bonded onlay, crown, root canal or extraction is the right answer.

Extraction & Replacement Options

When a tooth truly cannot be saved, we remove it gently and talk you through implant, bridge or denture options so there's a clear plan for what comes next.

Common Questions

Frequently asked questions

This is the question we're asked most, and the answer surprises people. The procedure is carried out under local anaesthetic, and the overwhelming majority of patients report it feels like having a large filling placed. The severe pain associated with root canals in the public imagination is the pain of the infected tooth beforehand — root canal treatment is what stops it. Afterwards the tooth may feel tender to bite on for a few days as the surrounding ligament settles, which normally responds well to over-the-counter anti-inflammatories. If you're worried, tell us and we'll discuss Penthrox or twilight IV sedation.

Common indicators include a lingering ache after hot or cold drinks, spontaneous throbbing pain that worsens at night or when lying down, pain on biting, swelling or tenderness in the gum near a tooth, a pimple-like bump on the gum that comes and goes, or a tooth that has darkened. That said, some infected teeth cause no symptoms at all and are only picked up on a routine X-ray — one more reason regular check-ups matter. If a painful tooth suddenly goes quiet, don't assume it has healed; the nerve may simply have died.

Cost depends heavily on which tooth is involved. A front tooth has a single canal and is a comparatively straightforward procedure; a molar can have three or four curved canals and takes considerably longer, sometimes over two visits. You also need to factor in the crown that usually follows a back-tooth root canal. Fees for root canal therapy typically span a wide range in Australia depending on tooth type and complexity, and private health extras generally contribute. We will always assess the tooth, take X-rays and give you a written quote covering both the root canal and the final restoration before starting, so you can weigh it against the alternatives.

Extraction is cheaper on the day, but it's rarely cheaper over a lifetime. Losing a tooth means neighbouring teeth drift, the opposing tooth over-erupts, chewing efficiency drops and the jawbone in that area gradually resorbs. Replacing the tooth with an implant or bridge typically costs substantially more than saving it. Nothing functions quite like your own tooth, and a well-treated, properly crowned root-filled tooth can last decades. There are situations where extraction is genuinely the better call — severe fracture, extensive decay below the gum, or poor bone support — and Dr Frame will tell you honestly when that's the case.

Many straightforward cases can be completed in a single longer visit. Teeth with active infection, significant swelling or complex canal anatomy are often better managed across two appointments, with a medicated dressing in between to allow the infection to settle. The crown, when needed, is usually fitted a few weeks after the root canal is complete, once we're confident the tooth is comfortable and stable. We'll outline the expected number of visits at your consultation.

A tooth needing root canal treatment has usually already lost a lot of structure to decay or fracture, and the access cavity removes more. Root-filled teeth are also drier and more brittle. Research consistently shows that back teeth restored with a cusp-covering crown or onlay survive far longer than those left with a filling alone — the crown holds the remaining walls together and prevents the vertical fracture that would otherwise mean losing the tooth. Front teeth with minimal damage can sometimes be restored with a bonded filling instead.

Success rates for well-performed root canal therapy are high — generally in the region of 85 to 95 per cent for teeth restored promptly with an appropriate crown. Outcomes are best when the tooth is treated before extensive infection develops, when the canals can be cleaned to their full length, and when the final restoration is placed without long delay. We review the tooth clinically and radiographically at your regular check-ups to make sure the bone around the root tip is healing as expected.
