If you have been told you need a root canal treatment, you are not alone. Root canal treatment is one of the most commonly performed dental procedures in Australia, and for many patients, it is the difference between keeping a tooth and losing it altogether. Despite its reputation, the procedure is straightforward, well-tolerated, and carried out under local anaesthetic — much like having a filling.
This article explains what root canal treatment involves, why it may be recommended, what to expect during and after the procedure, and how it compares to tooth extraction. If you have any concerns, the team at Dentists @ Canning Vale is here to help.
What Is a Root Canal Treatment?
Understanding the Purpose of Root Canal Therapy
Root canal treatment — also called endodontic treatment — is a dental procedure used to remove infected or damaged pulp from inside a tooth, clean and disinfect the root canals, and seal the tooth to prevent further infection. The goal is to save a tooth that would otherwise need to be extracted.
When the inner tissue of a tooth becomes infected or inflamed, simply treating the surface is not enough. Root canal therapy addresses the source of the problem directly, allowing the tooth to be retained and restored to full function.
Preserving natural teeth matters for more reasons than appearance. Your natural teeth maintain the alignment of surrounding teeth, support proper chewing function, and help preserve the bone structure of the jaw. Replacing a lost tooth — whether with an implant, bridge, or denture — is more involved and more costly than treating an infection early.
What Is Dental Pulp?
Inside every tooth, beneath the hard enamel and dentine layers, is a soft tissue called the dental pulp. The pulp contains nerves, blood vessels, and connective tissue. During childhood, pulp plays an important role in tooth development. In a fully formed adult tooth, the pulp is no longer essential for the tooth’s survival — the surrounding tissues provide enough nourishment.
When the pulp becomes infected or inflamed due to deep decay, a crack, or trauma, it cannot heal on its own. Bacteria multiply inside the pulp chamber and root canals, eventually leading to abscess formation, pain, and bone loss around the tooth if left untreated.
Why Might You Need a Root Canal Treatment?
Common Causes of Pulp Damage
Pulp damage can result from a number of situations:
- Deep tooth decay — when decay is left untreated, it progresses through the enamel and dentine until it reaches the pulp. At this stage, a filling alone is not sufficient.
- Cracked or fractured teeth — a crack in the tooth can allow bacteria to enter the pulp, leading to infection even without visible decay.
- Repeated dental procedures — teeth that have undergone multiple treatments over time can become more vulnerable to pulp inflammation.
- Dental trauma and injury — a knock to the mouth from sport, a fall, or an accident can damage the pulp internally, sometimes without the tooth appearing visibly broken.
Signs You May Need a Root Canal
Not all cases of pulp damage cause immediate or obvious symptoms. However, common signs that you may need root canal treatment include:
- Persistent or severe toothache that does not go away
- Prolonged sensitivity to hot or cold temperatures, even after the source is removed
- Swollen, tender, or darkened gums near the affected tooth
- Tooth discolouration (the tooth may appear grey or darker than surrounding teeth)
- Pain when biting or chewing
- A pimple-like bump on the gum (which may indicate an abscess)
These symptoms do not always confirm that root canal treatment is necessary — only a clinical examination and x-rays can determine the correct course of action. If you are experiencing any of these signs, it is worth having your teeth checked promptly.
Can a Tooth Infection Heal on Its Own?
A tooth infection involving the pulp does not resolve without treatment. Unlike soft tissue infections elsewhere in the body, an infected pulp has no blood supply capable of delivering the immune response needed to fight the bacteria. Without treatment:
- The infection can spread to surrounding bone and tissue
- An abscess may form at the tip of the root
- The infection can extend to the jaw, neck, or — in rare cases — beyond
- The tooth may eventually need to be extracted
The Australian Dental Association advises that delaying dental treatment for infection can lead to more serious complications. Early intervention is always preferable.
How Does a Root Canal Treatment Work?
Root canal treatment is typically completed over one to three appointments, depending on which tooth is being treated and the severity of the infection. Here is what the process involves.
Step 1: Examination and Diagnosis
Before any treatment begins, your dentist will carry out a thorough clinical examination of the affected tooth and surrounding area. This includes:
- Checking for signs of swelling, tenderness, or decay
- Taking dental x-rays to assess the shape and length of the root canals and the extent of infection
- Confirming the source and severity of the problem
In some cases, additional imaging or testing may be used to assess pulp vitality.
Step 2: Numbing the Area
Root canal treatment is carried out under local anaesthetic. The area around the affected tooth is numbed thoroughly before any work begins. Most patients report that the procedure itself is no more uncomfortable than having a routine filling. You should not feel pain during the treatment — if you do, tell your dentist immediately so the anaesthetic can be adjusted.
A rubber dam (a small sheet of latex or non-latex material) is placed around the tooth to keep it dry and free from saliva during the procedure.
Step 3: Removing the Infected Pulp
Once the area is numb:
- A small opening is made in the top of the tooth to access the pulp chamber
- The infected or inflamed pulp is removed using fine dental instruments
- The root canals are identified and carefully cleaned to remove bacteria and infected tissue
The number of root canals varies depending on the tooth. Front teeth typically have one or two canals; back molars may have three or more.
Step 4: Shaping and Disinfecting the Canals
After the pulp is removed, the root canals are shaped using small instruments to allow thorough cleaning. The canals are irrigated with an antibacterial solution to disinfect the space and reduce the risk of reinfection. This step is essential for long-term success.
Step 5: Filling and Sealing the Tooth
Once the canals are clean and dry, they are filled with a biocompatible rubber-like material called gutta-percha. This material seals the canals to prevent bacteria from re-entering. A temporary or permanent filling is then placed in the access opening.
Step 6: Restoring the Tooth
A tooth that has undergone root canal treatment is more brittle than a healthy tooth and is more susceptible to fracture. For this reason, a dental crown is usually recommended to protect the tooth and restore its full strength and appearance — particularly for back teeth that bear the force of chewing. In some cases, a large filling may be sufficient for front teeth. Your dentist will advise on the most appropriate restoration for your situation.
Does a Root Canal Hurt?
Understanding Modern Root Canal Procedures
Root canal treatment has a reputation for being painful, but this reputation is largely outdated. Modern techniques, instruments, and anaesthetic options have made root canal therapy a much more comfortable experience than it once was.
According to research published through the Australian Dental Journal, the majority of patients who have undergone root canal treatment report that it was no more painful than having a tooth filled. The discomfort patients associate with root canals is most often caused by the infection itself — not the treatment.
Local anaesthetic reliably numbs the area, and your dentist will not proceed until you are comfortable. If a tooth is severely infected and initially difficult to numb, your dentist may prescribe antibiotics to reduce the infection first before proceeding with treatment.
Managing Anxiety About Treatment
It is normal to feel apprehensive about dental procedures, including root canal treatment. A few things that may help:
- Talk to your dentist beforehand — understanding what will happen at each step can reduce uncertainty and anxiety
- Ask about sedation options — some clinics offer nitrous oxide (happy gas) or oral sedation for patients who are particularly anxious
- Use agreed signals — arrange a hand signal with your dentist to pause at any time if you feel uncomfortable
- Bring headphones — listening to music or a podcast during the procedure can help many patients feel calmer
If dental anxiety is a significant concern for you, let the team at Dentists @ Canning Vale know at the time of booking. We can discuss options to make your appointment as comfortable as possible.
What to Expect During a Root Canal Appointment
Before the Procedure
At your initial consultation, your dentist will:
- Review your dental and medical history
- Examine the tooth and take x-rays
- Confirm the diagnosis and discuss your treatment options
- Explain the procedure, expected outcomes, and costs
You do not need to do anything special to prepare for a root canal appointment. Eating normally beforehand is fine unless you have been advised otherwise. If you have been prescribed antibiotics prior to the procedure, complete the full course as directed.
During Treatment
A typical root canal appointment lasts between 60 and 90 minutes, though more complex cases — such as teeth with multiple canals or significant infection — may take longer or require a second visit. During the appointment:
- You will be seated comfortably with the dental light positioned over the working area
- Local anaesthetic is administered and time is given for it to take full effect
- The rubber dam is placed and the procedure proceeds as outlined above
- Your dentist will check your comfort regularly throughout
You will be awake and able to communicate with your dentist at all times.
After Treatment
Immediately after root canal treatment:
- The local anaesthetic will take a few hours to wear off — avoid eating on the treated side until sensation has returned fully to avoid accidentally biting your cheek or tongue
- Some mild soreness or tenderness is normal for the first few days and can usually be managed with over-the-counter pain relief such as paracetamol or ibuprofen, as directed
- You can return to normal daily activities straight away in most cases
- A follow-up appointment will be scheduled to place the final restoration (filling or crown)
Root Canal Recovery and Aftercare
Common Symptoms After Treatment
It is normal to experience some degree of:
- Mild tenderness around the treated tooth, particularly when biting down
- Temporary sensitivity in the surrounding area
- Jaw soreness from holding your mouth open during the appointment
These symptoms are generally mild and resolve within a few days. If discomfort persists beyond a week or worsens significantly, contact your dentist.
Caring for Your Tooth After a Root Canal
- Oral hygiene — continue brushing twice daily with fluoride toothpaste and flossing regularly. Good oral hygiene supports healing and protects the restoration.
- Eating and drinking — avoid hard, crunchy, or sticky foods on the treated side until the permanent restoration is in place. A tooth without its full crown is more vulnerable to fracture.
- Follow your dentist’s instructions — if antibiotics or pain relief medication have been prescribed, complete the course as directed.
When to Contact Your Dentist
Contact your dentist promptly if you experience:
- Severe or increasing pain that is not controlled by over-the-counter medication
- Visible swelling of the gum, face, or jaw
- Signs of infection such as fever, discharge from the gum, or a bad taste in the mouth
- The temporary filling coming loose or falling out
- Any problem with the crown or restoration once it has been placed
Benefits of Root Canal Treatment
Saving Your Natural Tooth
The primary benefit of root canal treatment is that it allows you to keep your natural tooth. A natural tooth performs better than any prosthetic replacement — it feels and functions like a normal tooth, maintains the alignment of adjacent teeth, and preserves the bone beneath it.
Preventing Further Infection
By removing the infected pulp and sealing the canals, root canal treatment eliminates the source of infection. This protects surrounding teeth and bone from the spread of bacteria and reduces the risk of systemic complications that can arise from untreated dental infections.
Restoring Comfort and Function
Once root canal treatment is complete and the tooth is properly restored:
- Chewing on the affected side becomes comfortable again
- The pain and sensitivity caused by the infection are resolved
- The tooth looks and functions normally
Root Canal Treatment vs Tooth Extraction
Why Saving a Tooth Is Often Preferred
Wherever possible, retaining a natural tooth is the preferred option. Tooth extraction eliminates the infection but creates a gap that — if not addressed — can cause the surrounding teeth to shift, affect your bite, and lead to bone loss in the jaw over time.
Replacing an extracted tooth typically requires one of the following:
| Replacement Option | Considerations |
| Dental implant | Most natural-feeling replacement; requires surgery, healing time, and higher upfront cost |
| Dental bridge | Requires alteration of adjacent teeth; no surgery needed |
| Partial denture | Removable; least invasive but least stable option |
In most cases, root canal treatment followed by a crown is less costly than extraction plus a dental implant, and it avoids the need for additional procedures altogether.
When Extraction May Be Necessary
There are situations where a tooth cannot be saved, and extraction is the appropriate course of action:
- The tooth is severely fractured at or below the gum line
- The bone loss around the tooth is too advanced
- The root canals are too calcified or complex to treat
- A previous root canal treatment has failed and retreatment is not viable
Your dentist will assess the tooth thoroughly before recommending extraction and will discuss all available options with you.
Long-Term Considerations
A tooth that has been successfully root canal treated and properly restored with a crown can last many years — in many cases, for the patient’s lifetime with appropriate care. The long-term cost and complexity of tooth replacement make preserving the natural tooth the more practical choice in most situations.
How Successful Is Root Canal Treatment?
Long-Term Success Rates
Root canal treatment has a well-established track record. Research published through the Journal of Endodontics and other peer-reviewed dental literature consistently shows high long-term success rates, particularly when the tooth is restored with an appropriate crown following treatment.
The success of root canal treatment depends in large part on how well the tooth is sealed and restored after the procedure. A tooth left with only a temporary filling is at risk of recontamination and fracture.
Factors That Influence Success
- Timely treatment — addressing pulp infection early, before it spreads to the surrounding bone, generally leads to better outcomes
- Oral hygiene habits — brushing, flossing, and managing diet reduces the risk of further decay around the restored tooth
- Regular dental visits — routine check-ups allow your dentist to monitor the treated tooth and detect any early signs of problems
Common Myths About Root Canal Treatment
Myth: Root Canals Are Extremely Painful
This is the most persistent myth about the procedure. Root canal treatment is carried out under local anaesthetic, and modern techniques have made the experience much more comfortable than its reputation suggests. The pain most patients associate with root canals is from the infection — not the treatment itself.
Myth: Tooth Extraction Is Always Better
Removing a tooth eliminates the immediate problem but creates new ones. A gap in the dental arch affects chewing, speech, and the position of adjacent teeth. Replacing an extracted tooth with an implant, bridge, or denture involves additional procedures, healing time, and cost. Where a tooth can be saved, saving it is generally the better long-term outcome.
Myth: Root Canal Treatment Causes Illness
This myth originated from poorly conducted research from the early twentieth century that has since been thoroughly discredited. There is no credible scientific evidence that root canal treatment causes systemic illness. Reputable sources including the Australian Dental Association confirm that endodontic treatment is a highly controlled, predictable, and routinely successful procedure.
Myth: The Tooth Will Eventually Need To Be Removed Anyway
A tooth that has been root canal treated and properly restored can last a very long time. Like all teeth, it requires good oral hygiene and regular dental monitoring — but there is no clinical basis for the assumption that root canal treatment is only a temporary measure.
How to Prevent the Need for a Root Canal
Good Oral Hygiene Habits
The most effective way to reduce the risk of pulp infection is to prevent deep decay from developing in the first place:
- Brush twice daily with a fluoride toothpaste, paying attention to the gumline and all tooth surfaces
- Floss daily to remove plaque and food debris from between the teeth where a toothbrush cannot reach
- Attend regular dental check-ups — routine examinations allow your dentist to identify and treat small areas of decay before they progress
The Australian Dental Association recommends a dental check-up every six to twelve months for most adults, though individual frequency may vary.
Protecting Your Teeth From Damage
- Wear a mouthguard during contact or collision sports. A custom-fitted mouthguard from your dentist offers better protection than an over-the-counter option.
- Avoid using your teeth as tools — opening packaging, biting nails, or chewing on pens and hard objects can crack teeth and allow bacteria to enter.
- Avoid chewing excessively hard foods such as ice or hard lollies, which can fracture teeth.
Treating Dental Problems Early
- Address cavities promptly — a small filling is a straightforward procedure. Leaving decay untreated allows it to progress toward the pulp, significantly increasing the complexity and cost of treatment.
- Monitor cracked or damaged teeth — if you notice a crack, chip, or sensitivity in a tooth, have it assessed. Cracks can be stabilised before they deepen.
- Don’t ignore dental pain — pain is a sign that something needs attention. An early assessment is almost always preferable to a delayed one.
