If you have been putting off a root canal because you are dreading the pain, you are not alone — and you are working off outdated information. We hear it almost every week from patients in Buderim: a dentist mentioned root canal treatment months, sometimes years, ago, and the appointment never got booked because the word alone was enough to cause a knot in the stomach.
Here is the plain truth. The pain people associate with root canals is almost always the pain of the infection that made the treatment necessary in the first place — not the treatment itself. Once the area is properly numb, a root canal feels much like getting a filling. Longer, yes. Painful, no.
Where the Reputation Comes From
Root canals earned their fearsome reputation decades ago, before modern local anaesthetic techniques and rotary instruments made the procedure faster and gentler. That reputation has stuck around in the culture — passed on in jokes and offhand comments — long after the dentistry itself moved on.
The other reason root canals get blamed for pain is timing. Most people who need one have already been in significant pain for days beforehand, from a tooth infection that has reached the nerve. That throbbing, keep-you-up-at-night pain is what people remember most vividly. It happened right before the treatment, so the treatment gets the blame — when really, the procedure is what makes that pain stop.
What Actually Hurts: The Infection, Not the Fix
Inside every tooth is a soft core called the pulp, containing nerves and blood vessels. When deep decay, a crack, or repeated dental work lets bacteria reach that pulp, it becomes inflamed and infected. An inflamed nerve inside a hard, confined space is one of the more intense pains the body can produce — there is nowhere for the swelling to go.
That is the pain that sends people searching “is a root canal painful” at 2am. By the time you are in the chair, the goal is to remove that infected tissue and relieve the pressure causing the pain — which is why most patients feel noticeably better within a day of having it done, not worse.
What Actually Happens, Step by Step
Numbing. We start the same way we would for a filling — a local anaesthetic injection around the tooth. This is normally the only part where you feel a pinch, and for a tooth that is acutely infected, we take extra time here to make sure the area is properly and fully numb before we begin any work.
Isolating the tooth. A thin rubber sheet, called a dam, goes around the tooth to keep it dry and free of saliva during treatment. It also means you are not aware of instruments near the back of your mouth.
Accessing the pulp. A small opening is made through the top of the tooth to reach the infected pulp chamber. Because you are numb, this stage feels like pressure and vibration rather than pain — similar to the sensation of a standard filling.
Cleaning and shaping the canals. Fine instruments remove the infected tissue from inside the root canals and shape them so they can be filled properly. This is usually the longest part of the appointment, but patients describe it as tedious rather than painful — you are simply sitting with your mouth open for a stretch.
Filling and sealing. Once the canals are clean, they are filled with a biocompatible material to prevent reinfection, and the access opening is sealed.
The final restoration. A tooth that has had root canal treatment is often more brittle afterward, so it usually needs a crown to protect it long-term. We will talk through timing and options for that at your appointment — more detail is on our root canal treatment page.
A straightforward root canal typically takes 60 to 90 minutes. Some cases, particularly molars with more complex root canal systems, need a second visit.
What You Feel Afterward
Once the anaesthetic wears off, mild soreness around the tooth for a day or two is normal — similar to what you would feel after a deep filling. Over-the-counter pain relief usually manages this, and most people are back to normal eating and activity within a couple of days.
Worth watching for: swelling that gets worse rather than better, or pain that intensifies rather than eases over the following days. If either happens, call us. It is uncommon, but worth checking rather than waiting out.
If You Are Still Anxious — Sedation Is an Option
Knowing the facts does not always undo years of built-up dental anxiety, and that is completely reasonable. If the thought of any dental appointment makes your chest tighten, we offer three levels of sedation to match how you are feeling — happy gas for a light, calming effect that wears off within minutes, oral sedation for a deeper sense of relaxation, or IV sedation for patients who need to be more deeply settled, with our practice manager Dwi George, a registered nurse, on hand. You can read more on our sedation dentistry page or our page for anxious patients.
We take the time to explain each stage as we go and adjust our pace to you, not the other way around. Dr Louis and Dr Jeremy both see a steady number of anxious patients and are used to talking people through treatment they have been avoiding for years.
Why Buderim Patients Put This Off Longer Than They Should
We see this pattern often in Buderim — a tooth has been niggling on and off for months, and the appointment keeps getting pushed back because of what people assume the treatment will involve. Retired patients in particular sometimes tell us they have been living with a dull ache since an old filling finally gave way, having decided it was “not bad enough yet” to deal with. University students commuting in from Sippy Downs and Mountain Creek often delay for a different reason — cost uncertainty rather than fear, not realising a proper assessment and clear quote is a simple first step.
Left untreated, an infected tooth does not resolve on its own. The infection can spread and the tooth becomes harder to save the longer it waits. The appointment you are avoiding is very often the thing that ends the pain you are already living with.
The First Step Is Just an Assessment
You do not need to commit to treatment to find out where you stand. A new patient visit at Sunny Dental Buderim is $249 and includes a scale and clean, dental x-rays, and a comprehensive check-up with either Dr Louis or Dr Jeremy over a full 50 minutes — enough time to actually look at what is going on and talk it through properly, rather than rush a diagnosis. Any further treatment, root canal or otherwise, is quoted separately once we know exactly what we are dealing with.
If a tooth has been bothering you and you have been putting it off out of fear of the treatment rather than the problem itself, it is worth having it looked at. Sunny Dental Buderim is at 2/64 King Street, Buderim, open Monday to Friday, 8:30am to 5:30pm. Call us on (07) 5445 8400 to book an assessment.
