If you’ve been lying awake at 11pm with a toothache, frantically Googling “does root canal hurt” — this post is for you.
Let me give you the honest answer upfront: with modern local anaesthesia, most people find root canal treatment feels very similar to having a large filling done. The area is completely numb before anything begins. If at any point during the procedure you feel discomfort, we stop and give more anaesthetic. The procedure that’s giving you sleepless nights is, in most cases, far more manageable than the pain you’re already experiencing.
The reputation root canal has is a relic. It’s worth understanding where it came from — because it tells a very different story to what treatment looks like now.
Why root canal got its reputation
The fear around root canal treatment is real and understandable — but it traces back to a different era of dentistry. Decades ago, achieving complete numbness in an infected tooth was genuinely difficult. Inflamed tissue changes the local pH in a way that reduces how effectively anaesthetic works, and techniques at the time weren’t as refined as they are today. The procedure was also more time-consuming, often spread across multiple appointments.
Modern anaesthesia options are significantly better. Delivery techniques have improved. Dentists now have a much deeper understanding of how to manage teeth that are harder to numb. The experience most people describe today is not what their parents or grandparents went through.
That reputation is unfortunately sticky — and in a place like Mawson Lakes and the northern suburbs, where busy schedules mean people often put off dental visits until pain becomes unavoidable, it causes real harm. The delay usually makes things worse.
When is root canal treatment actually needed?
Root canal treatment (also called endodontic treatment) becomes necessary when the soft tissue inside the tooth — the pulp — becomes infected or seriously damaged. The pulp contains nerves and blood vessels, and when it’s compromised, the body can’t resolve the infection on its own.
This can happen for several reasons:
- Deep decay that has worked its way through the outer layers of the tooth and reached the nerve — something that often develops gradually, without obvious pain until it’s already severe
- A cracked or fractured tooth that exposes the pulp to bacteria
- Repeated dental procedures on the same tooth over the years, which can gradually irritate the pulp
- A dental abscess — an infection at the tip of the root that can cause significant pain, jaw swelling, and if left untreated, more serious complications
At Smile Spot in Mawson Lakes, we use digital x-rays that can pick up problems in their earlier stages — sometimes before they’ve caused any noticeable pain at all. That’s one of the strongest arguments for regular checkups: catching decay when it’s still a filling rather than a root canal.
The symptoms that bring people in
The classic signs that a tooth may need root canal treatment include:
- A persistent, throbbing toothache that doesn’t go away on its own
- Sensitivity to heat or cold that lingers after the source is removed
- A tooth that has started to darken in colour
- Swelling or tenderness in the gum around the tooth
- A small pimple-like bump on the gum (which can be a sign of abscess)
And sometimes — none of the above. The problem shows up on an x-ray at a routine checkup, with no symptoms at all. That’s another reason digital x-rays are worth having regularly.
If you’re a parent in Parafield Gardens who’s been managing a toothache for weeks while looking after kids and trying to stay on top of work, you’re not alone. And if you’re a student at the nearby UniSA Mawson Lakes campus who’s been telling yourself you’ll sort it out after the semester ends — the semester ends and it’s usually worse. The pattern is very common. People put off the thing they fear, and in doing so, give the problem time to become harder to treat.
What actually happens during root canal treatment
Here’s a step-by-step picture of what to expect:
1. Anaesthesia
The area around the affected tooth is numbed with local anaesthetic. At Smile Spot, we don’t proceed until you’re fully numb — this is not something we rush. If you can still feel anything after the initial injection, you’ll be given more. There’s no reason to push through discomfort.
2. Rubber dam isolation
A thin rubber sheet is placed around the tooth to keep the area clean and dry and to prevent any material from going into your mouth. It might feel slightly odd for a moment, but most people forget it’s there within a minute or two.
3. Access to the pulp chamber
A small opening is made through the top of the tooth. Because the area is completely numb, you won’t feel this — you may be aware of pressure or vibration, but not pain.
4. Cleaning and shaping the canals
Small, flexible instruments are used to remove the infected or damaged pulp from the root canals and shape them carefully for filling. This is the core of the procedure. Depending on the number of canals and the complexity of the tooth’s anatomy, it can take some time — but none of it should be painful.
5. Filling the canals
Once the canals are clean and shaped, they’re filled with a material called gutta-percha — a biocompatible, rubber-like substance that seals the canals to prevent future infection.
6. Restoration
At the end of the appointment, a temporary or permanent filling is placed. For many patients, the next step is a crown. If timing works out, this can sometimes be done in the same visit.
What recovery actually looks like
After the anaesthetic wears off, it’s common to have some tenderness around the treated tooth for one to three days. The tooth might feel slightly different when you bite down on it. This is a normal healing response — not a sign that something has gone wrong.
Most people manage post-treatment discomfort comfortably with ibuprofen. Your dentist will advise you on what to take and when. Avoid chewing hard food on that side until the tooth has been properly restored, and you’ll generally be back to normal fairly quickly.
For someone commuting from Ingle Farm or Para Hills down Salisbury Highway every morning, a day or two of mild tenderness is a very manageable trade-off for resolving a toothache that’s been disrupting sleep and concentration for weeks.
Why keeping the tooth matters
Root canal treatment sometimes gets framed as the hard option. But it’s worth understanding what the alternative actually involves.
Extracting a tooth creates its own set of problems: neighbouring teeth can drift into the gap over time, bone loss can occur at the extraction site, and replacing a missing tooth — whether with an implant, bridge, or denture — involves its own cost, time, and further procedures.
A natural tooth, however battered, is generally worth preserving if it can be. A tooth that’s had root canal treatment can function normally for many years when it’s properly restored and cared for. That’s the goal: keep what you have.
The crown question
After root canal treatment, the tooth is structurally weaker than it was before — the removal of the pulp and the access opening both affect its integrity. For back teeth especially, a crown is almost always recommended afterward to protect against fracture.
At Smile Spot Mawson Lakes, we offer CEREC same-day crowns — the crown is designed, milled, and placed in a single appointment using in-house technology, without the temporary crown and multiple-week wait of traditional crown work. If you’ve already carved out time for the root canal, being able to complete the crown in one more visit rather than spreading it across weeks is genuinely more practical. Particularly if you’re working nearby at Edinburgh RAAF or Technology Park and taking time off isn’t straightforward.
Payment isn’t a barrier either
We offer DentiCare interest-free payment plans, which means the cost of treatment can be spread over time without credit cards or interest charges. For families in Mawson Lakes and surrounding areas — Salisbury, Paralowie, Pooraka — where a dental bill can feel like it’s competing with everything else, this is worth knowing before you decide to delay.
Appointments that fit around your life
Smile Spot Mawson Lakes is open Monday to Thursday until 7pm and Friday until 2pm. If you’ve been putting off an appointment because you work full days and can’t easily get away, an evening appointment takes that barrier away. Come in after work, get the tooth sorted, and be home at a reasonable hour.
Dr Sunny also speaks Punjabi, which makes a difference for patients from the significant Punjabi-speaking community across Mawson Lakes and Parafield Gardens — sometimes being able to talk through a procedure in your own language makes the whole thing feel far less daunting.
If you’re in pain, or you’ve been told you may need root canal treatment, or you just want a clear picture of what’s going on with a tooth — we’re here. Come in, have a look at the digital x-rays with us, and make an informed decision from there. There’s no pressure.
