Few phrases in dentistry make people flinch like root canal. The reputation is close to entirely undeserved, and it comes from a misattribution worth clearing up straight away.
Why the reputation is backwards
People arrive for root canal treatment in significant pain — that is usually what sent them. They associate the pain with the appointment.
But the pain was there before the treatment, caused by an inflamed or infected nerve inside a sealed, rigid tooth with nowhere for pressure to go. The treatment is what removes it. The tooth is numbed exactly as it is for an ordinary filling, and most people describe the appointment itself as long rather than painful.
The genuine downsides are that it takes time, usually more than one visit, and it costs more than a filling. Neither is the thing people are afraid of.
What actually happens
Inside every tooth is a chamber and a set of canals running down each root, containing the nerve and blood supply — the pulp. When decay, a crack or trauma lets bacteria in, that tissue becomes inflamed and then infected, and it cannot recover on its own.
The procedure:
- The tooth is numbed.
- An opening is made through the top of the tooth.
- The infected pulp tissue is removed from the chamber and each canal.
- The canals are cleaned, shaped and disinfected — this is the part that takes the time.
- They are filled and sealed so bacteria cannot re-enter.
- The tooth is restored on top, often with a crown on back teeth.
A tooth with no nerve is still a functioning tooth. It stays in the jaw, it chews normally, and it keeps its neighbours from drifting. What it loses is the ability to feel temperature — and to warn you about new problems, which is why it still needs checking.
The actual decision: save it or remove it?
This is the choice that matters, and it is worth understanding rather than deferring.
| Root canal treatment | Extraction | |
|---|---|---|
| Keeps the tooth | Yes | No |
| Visits | Usually 2+ | Usually 1 |
| Cost on the day | From RM300 per visit | From RM100 |
| Cost over ten years | The tooth, plus a crown if needed | Extraction, then bridge/denture from RM450+ if the gap is filled |
| The gap | None | Neighbouring teeth can drift; opposing tooth can over-erupt |
| Bone | Stimulated normally by the root | Bone at the site gradually resorbs |
| Best when | Enough sound tooth remains to restore | Too little tooth left, or a root is fractured |
Extraction is cheaper on the day and usually more expensive over a decade, because a gap in the chewing surface tends to want filling eventually — and the replacement costs more than the root canal would have.
But extraction is genuinely right sometimes: when a root is fractured, when there is not enough sound tooth left to hold a restoration, or when the tooth is a wisdom tooth nobody needs. A dentist who never recommends extraction is not being straight with you either.
How many visits, and why does the price differ between teeth?
Because teeth differ.
A front tooth typically has one canal. A back molar can have three or four, each of which must be found, cleaned along its full length, shaped and sealed independently. Curved or unusually narrow canals take longer again.
That is the whole explanation for both the visit count and the fee difference. It is not a pricing tier; it is the anatomy.
Why a crown afterwards?
A tooth that has had root canal treatment has had structure removed from inside it, and it no longer has the blood supply that kept it slightly flexible. Under chewing forces — particularly on molars, which take the most load — it becomes more likely to fracture.
A crown wraps and holds it. A fractured root-treated tooth usually cannot be saved a second time, so the crown is protecting the work rather than adding to the bill.
Whether yours needs one depends on how much sound tooth is left. It should be discussed as part of the plan, before treatment, not raised afterwards.
What to expect afterwards
- Tenderness for a few days, especially on biting, is normal. The tissue around the root tip has been inflamed and takes time to settle.
- Simple painkillers manage it.
- Avoid heavy chewing on that side until the tooth is permanently restored — a temporarily filled tooth is more fragile than a finished one.
- Go back if pain increases rather than decreasing after the first few days, or if swelling appears. That is not the normal course.
What we do at FTS Chin Dental
We try to save teeth where saving them is the better answer, and we say so plainly when it is not.
The assessment covers how deep the decay or infection goes, how much sound tooth remains, whether the root is intact, and what the X-ray shows at the root tip. Then we explain both options — keeping it and removing it — with what each involves and costs, before anything starts.
Root canal treatment is from RM300 per visit and extraction from RM100, both confirmed for your specific tooth after examination. Prices are published on our fillings and root canal page and our extraction page.
