Extract or save? When a tooth is truly beyond repair

You have been told your tooth needs to come out. You agree, because you cannot see any other option, but you leave with the feeling that you decided too quickly. And above all with the question of whether the tooth really could not have been saved.

It is a good question. In this article we explain what actually determines whether an extraction happens at all.

When a tooth can still be saved

Let us start with the more pleasant part, because patients are usually surprised by how many teeth can be saved.

A tooth can usually be saved as long as enough of it remains. In practical terms, that means it still has load-bearing walls, the root is intact and the bone around it holds firm. Even teeth that look hopeless can often be saved: deep tooth decay, a broken-off piece, repeated inflammation around the root, even a tooth without a nerve.

What matters is therefore not how the tooth looks in the mirror, but what remains of it once the decay and old filling material have been removed. And that only becomes clear during treatment, not beforehand. This is why you sometimes only learn the final decision in the chair.

When saving no longer makes sense

There are, however, situations where an attempted rescue is only a postponement, and one you pay for. A tooth usually cannot be saved when:

• the decay reaches deep below the gum
• the root is cracked lengthwise
• the bone around the tooth has receded, so it is loose and has no support
• the inflammation keeps returning even after root canal treatment and a surgical solution is not possible
• the tooth stands in the way of planned treatment, for example before straightening the teeth

What the decision is based on

When the situation is borderline, the dentist looks at four things.

It depends on how much of the tooth is actually left – whether it still has solid walls or is just a thin shell. Then on the condition of the bone around the tooth, because that is what gives it support. Next, on the chances that the rescue will succeed and how long the tooth would then last. And finally, on how many visits and how much money it will cost compared with going straight for a replacement.

These last two considerations – prognosis and cost – are closely linked. Saving a questionable tooth takes more visits and sometimes ends in extraction anyway, just two years later and at a higher price. At other times the tooth lasts for years and is well worth it. Which of those two paths lies ahead of you depends on the prognosis, and only a dentist can estimate that, not you.

What to ask before you decide

Five questions that move the conversation from “it has to come out” to a decision you actually understand:

1. Can this tooth still be saved, and how?
2. What is the prognosis and how long is it likely to last?
3. How many visits and how much money will it cost compared with extraction and a replacement?
4. What happens if I wait? With some findings, waiting does no harm; with others, bone keeps disappearing.
5. What will you replace the tooth with, and when? Ask before the tooth comes out.

The last point is especially important. After the tooth, a gap remains and the surrounding teeth react to it: the neighbouring teeth tilt, the opposing tooth moves out of its socket and the bone in the area shrinks, most of all in the first year. The most common replacement at our clinic is a dental implant, which fills the gap including the root. In some situations the replacement is planned before the procedure itself, because it makes the whole solution simpler.

The extraction and everything that follows it can be found at our clinic under tooth extraction. How the procedure works and how long healing takes is covered there in detail.

Frequently asked questions

How do I know whether my tooth can still be saved?

What matters is how much healthy tooth tissue remains, whether the root is intact and how much bone holds it in place. This can only be known for certain once the decay and old filling material have been removed.

Can I ask for a second opinion?

You can, and with borderline teeth it makes sense. Bring your X-ray with you – it will save you a new one.

Is it cheaper to save a tooth or to extract it?

The extraction itself is cheaper than saving the tooth. But it is usually followed by a replacement, and that costs more than saving the tooth would have. So the deciding factor is how long the saved tooth would last.

Do I have to deal with a replacement after the extraction?

For most teeth, yes, because the neighbouring teeth tilt and the bone in the gap shrinks. The exception is a wisdom tooth, which we usually do not replace. Why you should not put the gap off, and what an implant solves, is covered on our dental implants page.

Conclusion

The decision between saving a tooth and extracting it does not rest on how the tooth looks, but on what remains of it and how long the rescue would last. You have the right to hear the prognosis before you decide, and you have the right to know the cost of both paths.
