Root Canal Therapy
A root canal removes infected or dying tissue from inside a tooth so the tooth itself can stay in your mouth. It is one of the most common procedures in dentistry, and for most people it is the difference between keeping a natural tooth and replacing it.
- Typical appointment
- 60–90 minutes
- Anaesthetic
- Local; sedation available
- Back to work
- Usually the same day
What is actually being treated
Inside every tooth, beneath the hard enamel and dentin, is a soft core called the pulp. It contains the nerve and the blood supply that fed the tooth while it was developing. When decay reaches that core, or a crack lets bacteria in, or a knock damages the blood supply, the pulp becomes inflamed or infected.
Once that happens the pulp does not recover on its own. The infection spreads down the root canals toward the tip of the root and into the bone, which is what produces an abscess. Root canal therapy removes the diseased tissue, disinfects and shapes the canal system, and seals it so bacteria cannot re-enter.
The tooth stays. The root stays in the bone. What is removed is tissue the adult tooth no longer needs.
A treated tooth is not a dead tooth in the way people imagine — it is a tooth whose infection has been removed and whose structure has been kept.
When to have it looked at
Signs a tooth may need root canal treatment
Not every one of these means a root canal. All of them mean the tooth should be examined rather than watched.
Pain that lingers
Sensitivity to hot or cold that continues for more than a few seconds after the source is removed.
Pain on biting
Discomfort when chewing or when pressure on the tooth is released.
Swelling or a gum pimple
Tenderness in the gum near the tooth, facial swelling, or a small recurring bump that may drain.
A tooth that has darkened
A single tooth turning grey or brown compared with its neighbours often means the pulp has died.
A crack, chip or deep filling
Damage that reaches the pulp can allow bacteria in long before pain begins.
Pain that wakes you
Throbbing that is worse lying down is a classic sign of pulp inflammation.
Some infected teeth produce no symptoms at all and are found on a routine X-ray. Absence of pain is not proof that a tooth is healthy.
What to expect
The appointment, step by step
Knowing the sequence removes most of the anxiety people bring with them.
-
01
Diagnosis and imaging
The tooth is tested and imaged so the canal anatomy is understood before anything begins. Where a standard X-ray is not conclusive, three-dimensional imaging shows the roots from every angle.
-
02
Anaesthetic
The tooth and surrounding tissue are numbed thoroughly. You should feel pressure and movement, but not sharp pain. Tell us immediately if you do — more anaesthetic can be given at any point.
-
03
Isolating the tooth
A thin sheet called a dental dam is placed so the tooth stays clean and dry, and so nothing used during treatment reaches the rest of your mouth.
-
04
Accessing and cleaning the canals
A small opening is made through the crown. The diseased pulp is removed and each canal is cleaned, disinfected and shaped. This is the part that takes the time, and it is done under a surgical microscope because canals are frequently narrower than a hair and rarely straight.
-
05
Sealing
The cleaned canals are filled with a biocompatible material and sealed so bacteria cannot travel back down them. A temporary filling closes the access opening.
-
06
Restoring the tooth
You return to your general dentist for a permanent restoration — usually a crown on back teeth, because a treated molar needs protection from the forces of chewing. This step matters as much as the root canal itself.
The real decision
Save the tooth, or remove it?
Root canal therapy
- The natural root stays in the jaw, and the bone around it keeps its stimulus.
- Your bite, your neighbouring teeth and your speech are unchanged.
- Usually completed in one or two visits.
- Generally the lower total cost once replacement of an extracted tooth is counted.
- The tooth can still be extracted later if it ever fails — the option is not lost.
Extraction and replacement
- The gap must be restored, or the neighbouring teeth drift and the opposing tooth over-erupts.
- Bone in the empty socket resorbs over time.
- An implant involves surgery and a healing period, often several months.
- A bridge requires cutting down the healthy teeth on either side.
- Sometimes genuinely the right answer — a tooth that is split vertically or has too little structure left cannot be saved.
The purpose of a consultation is to work out honestly which of these applies to your tooth. If it cannot be saved, you will be told so plainly rather than sold a treatment that will not last.
Afterwards
Recovery and aftercare
Most people describe the days after treatment as mild soreness rather than pain, and manage comfortably with over-the-counter analgesia.
- Expect tenderness when biting for a few days — the ligament around the root has been irritated.
- Take pain relief as advised before the anaesthetic wears off, rather than waiting for discomfort to start.
- Avoid chewing on the treated side until the permanent restoration is placed; a temporary filling is not built for full force.
- Continue brushing and flossing the tooth as normal.
- Book the permanent crown or filling promptly — an unrestored treated tooth can fracture, and that is the most common reason treatment fails.
- Call us if swelling increases, if pain is severe or worsening after the first few days, or if your bite feels high.
Questions patients actually ask
Root canal FAQs
Does a root canal hurt?
The procedure is carried out under local anaesthetic, and the experience is comparable to having a large filling placed. Most of the pain people associate with root canals is the pain of the infection that brings them in — which the treatment relieves. If you feel anything sharp during treatment, say so and more anaesthetic will be given.
How long does a root canal take?
Most treatments are completed in a single visit of about sixty to ninety minutes. Molars have more canals and complex anatomy, and a badly infected tooth sometimes needs a second appointment so medication can work inside the canal between visits.
How long will the tooth last afterwards?
A tooth that has been properly treated and then properly restored can function for many years. The most important factor is the restoration: a back tooth that is not crowned after treatment is at real risk of fracturing. Long-term outcome also depends on your gum health and on the amount of natural tooth structure remaining.
Can I drive home afterwards?
Yes, if you have had local anaesthetic only. If you choose sedation you must arrange for someone to drive you home and stay with you.
Why see an endodontist rather than my general dentist?
Endodontists complete two or more additional years of accredited postgraduate training focused solely on the inside of the tooth, and perform these procedures every day. Complex anatomy, a previously treated tooth, a calcified canal or a tooth that has not settled after treatment are all reasons a general dentist refers to a specialist.
Will I need a crown afterwards?
Usually, on back teeth. Chewing forces on molars and premolars are high, and a treated tooth has an access opening through its biting surface. Your general dentist will advise on the specific restoration; we will tell you what the tooth needs and send that recommendation on.
Is a root canal safe if I have other health conditions?
Bring a full list of your medical conditions and medications to the consultation, including blood thinners and bisphosphonates. Treatment is routinely provided for patients with a wide range of medical histories, but the plan is adjusted to your circumstances.
Not sure whether your tooth can be saved?
A consultation and the right imaging will answer that question properly. If the tooth cannot be saved, we will tell you.
