If you’ve been told you need a root canal, or you’re worried you might, take a breath; they have a far worse reputation than they deserve. A root canal is a routine treatment that relieves pain rather than causes it, and it saves a tooth that would otherwise be lost. This guide from Marsfield Dental Care in Sydney walks you through exactly what to expect, step by step, and what affects the cost, so you can approach root canal treatment in Sydney feeling informed rather than anxious.
| Quick answer
A root canal removes infected tissue from inside a tooth so it can be saved rather than extracted. With modern anaesthetic, it usually feels similar to a large filling, and it relieves the pain caused by the infection. Most root canals take one or two visits; cost depends on the tooth and complexity. |
What is a root canal and why might you need one?
Inside every tooth, beneath the hard outer layers, is a soft centre called the pulp, which contains the nerve and blood supply. When that pulp becomes infected or badly inflamed, usually from deep decay, a crack, or an injury to the tooth, it can be very painful and won’t heal on its own. A root canal treats exactly this: it removes the infected or damaged pulp from inside the tooth, cleans out the space, and seals it, so the tooth can stay in place rather than being pulled out. The signs you might need one vary, but common ones include a persistent toothache, lingering sensitivity to hot or cold, pain when biting, swelling or tenderness in the gum near a tooth, or a tooth that has darkened. Sometimes there are few symptoms, and it’s picked up on an X-ray. If you notice any of these, it’s worth getting it checked promptly, because treating an infection early is more comfortable and gives the tooth the best chance. Left alone, the infection tends to get worse, not better, and can spread.
What to expect during the procedure
The idea of a root canal sounds daunting, but the appointment itself is more straightforward than most people imagine. Here’s what generally happens:
Diagram of a tooth undergoing root canal treatment
- Diagnosis: your dentist examines the tooth and takes an x-ray to confirm the problem and plan the treatment.
- Anaesthetic: the area is numbed with local anaesthetic, so the tooth and surrounding gum are thoroughly numb before anything starts.
- Cleaning: your dentist removes the infected pulp, then carefully cleans and shapes the canals inside the roots to clear the infection.
- Filling: the cleaned canals are sealed with a special filling material to prevent reinfection, and the tooth is closed up.
- Crown: because a treated tooth can become more brittle, a crown is often placed afterwards to protect and strengthen it, sometimes at a later visit.
Most root canals are completed in one or two visits, depending on the tooth and how many canals it has. Throughout, the goal is simple: clear the infection and save the tooth so you keep your natural tooth rather than losing it.
Does it hurt, and what’s recovery like?
This is the question on everyone’s mind, and the reassuring answer is that a root canal today is very different from its old reputation. During the procedure, the tooth is fully numbed with local anaesthetic, so you shouldn’t feel pain, and most people say it feels much like having a large filling done. In fact, because a root canal relieves the pain of the infection, many people feel far better afterwards than they did before. For a few days after, it’s normal for the tooth or gum to feel a little tender or sensitive, especially when biting, and this usually settles on its own and can be managed with simple over-the-counter pain relief. Your dentist will give you aftercare advice, which typically includes being gentle on the tooth until any final restoration or crown is in place. Most people get back to their normal routine straight away. If you have any significant or worsening pain afterwards, you’d contact the practice, but for the vast majority, recovery is smooth and uneventful.
What affects the cost of a root canal?
Like most dental treatment, a root canal isn’t a single fixed price, because a few things affect it. The tooth itself matters most: front teeth generally have a single canal, while back teeth (molars) have several, so they take more time and work to treat, which affects the cost. The number of canals and the complexity of the tooth’s anatomy therefore play a big part. Whether the tooth needs a crown afterwards is another factor, and it often does, since a dental crown protects a treated back tooth from fracturing, and that’s a separate part of the overall cost. The condition of the tooth and whether any complications are involved can affect it too. Because all of this varies from tooth to tooth, an accurate figure comes from an examination, where your dentist assesses the specific tooth and gives you a clear quote before treatment begins. Saving a natural tooth with a root canal is very often more cost-effective in the long run than losing it and replacing it later.
Frequently asked questions
Is a root canal painful?
Not the way its reputation suggests. The tooth is fully numbed with local anaesthetic during treatment, so you shouldn’t feel pain, and most people liken it to having a large filling. Because it relieves the infection that was hurting, many feel better afterwards. Mild tenderness for a few days is normal and settles with simple pain relief.
How long does a root canal take?
Most root canals are completed in one or two visits, depending on the tooth and how many canals it has. A front tooth with a single canal is quicker than a molar with several. Your dentist will let you know how many appointments your tooth is likely to need after examining it.
Do I need a crown after a root canal?
Often, yes, particularly for back teeth. A treated tooth can become more brittle over time, and a crown protects and strengthens it so it can keep functioning normally. Front teeth don’t always need one. Your dentist will advise whether a crown is recommended for your tooth as part of the treatment plan.
Final thoughts
A root canal isn’t something to fear; it’s a routine, comfortable treatment that clears infection, relieves pain and saves a tooth you’d otherwise lose. Knowing what to expect makes it far less daunting, and the cost depends simply on the tooth involved. If you’ve got a painful or troublesome tooth, don’t put it off.
