Signs You Need a Root Canal: A Two Rocks Guide

A toothache that won't settle down is hard to ignore. If you've been pushing through pain, noticing a tooth that looks darker than the rest, or feeling a twinge every time you drink something cold, you might be wondering if you need a root canal. At Two Rocks Dental Care, we see this worry often, and we want to walk you through what to look out for, in plain language, without the scare tactics.

A root canal sounds worse than it is. It's simply a treatment that cleans out the inside of a tooth when the soft tissue in the middle, called the pulp, has become infected or damaged. The healthdirect explains that root canal treatment is a dental procedure that removes infected soft tissue (pulp) from inside your tooth, and it can help save your damaged or infected tooth. The aim is always to save your natural tooth rather than remove it.

What causes the pulp to become infected

Inside every tooth, under the hard outer layer, sits a soft core made up of nerves and blood vessels. Dentists call this the pulp. Several things can let bacteria reach it and cause trouble.

• Deep decay that's been left untreated
• A crack or chip in the tooth
• An old filling that has broken down
• A knock or injury to the tooth
• Repeated dental work on the same tooth over the years

Once bacteria get into the pulp, the tissue becomes inflamed or infected. Without treatment, the infection may get worse and your tooth may need to be removed. That's why it's worth getting things checked early rather than waiting.

Common signs you need a root canal

Pain that lingers or keeps coming back

A short twinge from something cold usually settles quickly and isn't a big worry. But pain that hangs around, throbs, or wakes you up at night is a different story. This kind of ongoing ache can mean the pulp inside the tooth is inflamed and struggling to heal on its own.

Sharp pain with hot or cold food and drinks

Everyone gets a bit of sensitivity now and then. The difference worth noting is how long it lasts. If a sip of tea or a mouthful of ice cream sets off pain that lingers well after the hot or cold is gone, that's worth mentioning at a check-up.

A tooth that looks darker than its neighbours

Sometimes a tooth gradually turns grey, yellow or brownish compared to the teeth next to it. This change usually comes from inside the tooth, often because the pulp tissue has been damaged. It's not always obvious straight away, which is one reason regular check-ups matter.

Swelling or tenderness in the gum

A tender, puffy area in the gum near one particular tooth can be a sign that something is going on underneath. Sometimes it comes and goes, which can be misleading. Swelling settling down doesn't always mean the problem has gone away, it may just mean it's draining for a while before flaring up again.

Pain when you bite or chew

If one tooth feels tender or "high" when you bite down, or you find yourself chewing on the other side of your mouth without really noticing, that's worth getting looked at. This kind of discomfort can be easy to live with for a while, but it tends to get worse rather than better on its own.

A cracked or chipped tooth

A crack can let bacteria sneak into the pulp even before any pain starts. If you've chipped a tooth on something hard or had a knock to the mouth, it's worth having it checked, even if it doesn't hurt yet.

What happens if you leave it

It's tempting to wait and see, especially if the pain comes and goes. But an infected tooth doesn't fix itself. Left alone, the infection can spread further into the tooth and surrounding bone, and the pain usually gets worse rather than better. At that point, removing the tooth may become the only option, when a root canal earlier on could have saved it.

If you ever notice spreading facial swelling, a fever, trouble breathing or swallowing, or bleeding that won't stop, these need urgent attention. Go to a hospital emergency department straight away rather than waiting for a regular appointment.

What we do at Two Rocks Dental Care

If you come in with any of these symptoms, we'll start with a proper look and an X-ray. We take an OPG, which is a single panoramic X-ray showing all your teeth and jaw, right here at the practice, so you don't need a separate trip anywhere else.

From there, we talk you through what's going on and the options available, including our approach to root canal therapy, with the pros and cons of each path so you can make the choice that feels right for you. If a tooth has been weakened by the infection or by the treatment itself, we may also talk about protecting it afterwards with a crown, which you can read more about on our crowns and bridges page. Sometimes extraction is the better option for a particular tooth, and if that's the case, we'll explain why and what comes next, including how a missing tooth might later be replaced with a bridge, denture or dental implant.

Being local matters here too. Families across Two Rocks, Yanchep and the rest of Perth's northern coast don't need to drive down to Joondalup just to get a painful tooth sorted. You can come to us, get it looked at properly, and get a clear plan.

Managing pain while you wait for your appointment

If you're in discomfort before your visit, a few simple steps can help:

• Take pain relief following the directions on the packet, or ask your pharmacist what's suitable for you
• Rinse gently with warm salty water a few times a day
• Avoid chewing on the sore side and steer clear of very hot or cold food and drink

These steps are just to make you more comfortable, not a substitute for being seen. If your pain is severe or you notice swelling spreading, please get checked sooner rather than later.

Frequently asked questions

Does a root canal hurt?

The treatment itself is done with a local anaesthetic to numb the area, and our team talks you through each step so you know what to expect. Many people find the infected tooth was far more uncomfortable than the appointment to fix it.

How many visits does a root canal take?

You may need more than one visit to your dentist for this treatment, and root canal treatment usually requires a few dental appointments. We'll give you a clear idea of the plan once we've had a proper look at the tooth.

Can I just have the tooth taken out instead?

If you have a badly damaged or infected tooth, you could choose to have your tooth removed instead of having a root canal treatment. We'll always explain both options honestly, including what each one means for your bite and neighbouring teeth, so you can decide what's right for you.

What if I'm not sure it's serious enough for an appointment?

If you're unsure, it's always worth getting it checked rather than waiting. Mild symptoms can sometimes point to a bigger issue underneath, and catching it earlier usually means simpler treatment.

How much will a root canal cost?

Cost depends on things like which tooth is affected, how many canals it has, and whether a crown is needed afterwards. We'll give you a written quote with item numbers so you can check it against your health fund. As a preferred provider for HBF, HCF and nib, we can process your claim on the spot through HICAPS, which usually means a smaller gap for you to pay. If your extras cover has a yearly limit, most funds reset this on 31 December, though it's worth checking your own fund's reset date.
