Root canal or extraction: when can a tooth be saved?
In short: whenever a tooth can be saved, keeping it with a root canal is usually the best option, because nothing matches your natural tooth. Extraction is reserved for when it is too badly destroyed or the infection can’t be controlled. And note: pulling it seems cheaper, but the gap then calls for an implant or bridge, so saving the tooth usually works out better value.
The general rule: keep it whenever you can
In modern dentistry there’s a clear principle: the best tooth is your own. No implant or prosthesis, however good, beats a healthy natural tooth. That’s why, faced with a tooth with a damaged nerve, the first question is: can it be saved? If the answer is yes, the root canal wins almost every time.
When can it be saved with a root canal?
When the tooth, even with an infected nerve or deep decay, still has enough structure to be rebuilt afterwards. The root canal cleans and seals the inside, and then it is restored (usually with a crown, as we see in after a root canal, do I need a crown?). We explain exactly what it is in what a root canal is.
When is it better to extract?
There are situations where the tooth has nothing left to give:
- It is broken or destroyed below the gum line, with nothing to rebuild.
- The infection can’t be controlled even with treatment.
- There is gum disease so advanced that the tooth no longer has support.
In those cases, insisting on saving it would only drag out the problem. Extraction is the sensible choice.
The cost factor (that hardly anyone explains)
At first glance, extraction is cheaper. But the story doesn’t end there:
| Option | Apparent cost | Real long-term cost |
|---|---|---|
| Root canal + crown | Medium | That’s the end of it; you keep your tooth |
| Extraction “and that’s it” | Low | The gap causes problems (see below) |
| Extraction + implant/bridge | — | High (more than saving the tooth) |
Leaving the gap isn’t free: the neighbouring teeth move, chewing becomes harder and bone is lost. That’s why, if a tooth is extracted, you almost always have to replace it with an implant or a prosthesis, which cost more than the root canal that would have saved the tooth.
The decision, with an X-ray in front of us
This isn’t a decision made “by ear”: it’s taken by looking at the tooth and an X-ray. If you have a damaged tooth and you’ve been given the choice, come in and we’ll assess it honestly, looking out for your mouth and your wallet. The first visit is free. Book an appointment as soon as you can.
Frequently asked questions
Is it better to have a root canal or pull the tooth?
Whenever it can be saved, keeping your own tooth is usually the best option: nothing works as well as your natural tooth. Extraction is reserved for when the tooth is too badly destroyed or the infection can't be controlled. The dentist decides after an X-ray.
Is it cheaper to pull the tooth than to have a root canal?
In the short term, extraction seems cheaper. But that gap then usually needs an implant or a bridge so you don't lose function, and that costs quite a bit more. Saving the tooth with a root canal is usually cheaper in the long run.
What happens if I pull the tooth and put nothing in its place?
Leaving the gap has consequences: the neighbouring teeth tilt, the one opposite drifts down, chewing and cleaning become harder, and bone is lost in the area. That's why, if a tooth is extracted, it almost always pays to replace it.
