Pivot Tooth: What a Tooth With a Pin Actually Is and How It Works

What is a tooth with a pin called?

A tooth rebuilt around a pin is called a post and core crown. The pin itself is a post, the material built up around it is the core, and the visible part on top is a crown. Together they replace a natural tooth crown that has broken down too far to hold a filling, using the remaining tooth root as an anchor.

You will also see this restoration called a post crown, a pin crown, a dowel crown or – translated fairly literally from other languages – a pivot tooth. They all describe the same thing.

Why "pivot tooth" is a term you will mostly hear in translation

"Pivot tooth" is not standard clinical English. It is a direct translation of terms that are perfectly normal in other languages: dent à pivot in French, diente de pivote or corona pivot in Spanish, dente a perno in Italian. Patients who first heard about the treatment in one of those languages naturally search for "pivot tooth" in English – which is exactly why this page exists in both vocabularies.

If you want to talk to a US dentist about it, the terms that will be immediately understood are post and core and post crown. If you have been told you need a "pivot tooth," you have been told you need a post and core crown.

Post, core, crown: what each part does

The important point: a post does not strengthen a tooth. That is the most persistent myth about this treatment. A post is a retention device – it holds a build-up in place when there is not enough tooth left to hold it otherwise. Preparing the canal for a post actually removes tooth structure, so a post is placed because it is necessary, not because it makes the tooth tougher.

What types of dental posts are there?

The practical difference between fiber and metal is not mainly strength – it is what happens when things go wrong. A stiff metal post transfers chewing forces into the root and, in an unfavorable case, contributes to a root fracture that ends the tooth. A fiber post is more likely to loosen or debond first, which is a repairable failure. That is why fiber posts have become the default in many practices, particularly for front teeth.

How long does a pivot tooth last?

Published survival figures for post and core crowns are generally reported in the range of about 80 to 90 percent at five years, with results declining over longer periods and varying widely depending on the case. The variation matters more than the average, because the outcome is largely decided by factors that can be checked in advance:

The most common reasons a post crown eventually fails are decay at the crown margin, the post debonding, and root fracture. The first two are usually repairable. A vertical root fracture is not – that tooth has to come out.

Pivot tooth or dental implant: which makes more sense?

This is the decision most patients are actually weighing, and the honest answer is that it depends on the root, not on a general ranking of the two treatments.

If the root is healthy, the root canal filling is sound, and there is a proper ferrule, keeping your own root is normally the better choice. A natural root is suspended in the jaw by the periodontal ligament, which senses pressure and preserves surrounding bone. No implant reproduces that. Keeping the tooth is also less invasive, faster and usually cheaper.

If the root is fractured, decayed below the bone level, or too compromised to carry a crown, then a titanium implant or a bridge is the more predictable option. Building an expensive crown on a doomed root simply delays the same decision by two or three years, at full cost.

A reasonable way to frame it with your dentist: "What is the realistic five-year prognosis for this root, and what does the fallback look like if it fails?" If the answer to the second half is "we would place an implant anyway," you at least know what you are choosing between.

What other alternatives exist?

Where a post is not indicated, options include an inlay or onlay if more tooth remains than first assumed, a crown without a post when the build-up can be bonded to existing walls, a bridge using neighboring teeth, or a removable partial denture where several teeth are missing.

Frequently asked questions

What is a tooth with a pin called?

It is called a post and core crown, or simply a post crown. The pin is the post, the build-up around it is the core, and the cap on top is the crown. "Pivot tooth" and "pin tooth" describe the same restoration in less formal or translated language.

Is a pivot tooth the same as a dental implant?

No. A pivot tooth uses your own remaining tooth root as its anchor, with a post cemented inside the root canal. A dental implant replaces the root itself with an artificial screw placed in the jawbone, and is used when the natural root is gone or unsalvageable.

Does getting a post in a tooth hurt?

Not usually. The tooth has already had its nerve removed during root canal treatment, and the procedure is carried out under local anesthesia. Most patients report pressure rather than pain. Mild gum soreness for a few days afterward is normal.

Does a post make a tooth stronger?

No – this is a widespread misunderstanding. A post provides retention for a build-up; it does not reinforce the root. Preparing the canal for a post removes tooth structure, so posts are used only when there is not enough tooth left to hold a restoration any other way.

How long does a post and core crown last?

Reported survival is commonly in the region of 80 to 90 percent at five years, with wide variation. Front teeth, a good ferrule, a sound root canal filling and controlled grinding all push results toward the upper end; molars, bridge abutments and untreated bruxism push them down.

Can a pivot tooth be replaced if it fails?

Often yes. If the crown or post has simply debonded, it can frequently be re-cemented or remade. If decay has undermined the margin, the tooth can sometimes be rebuilt. A vertical root fracture, however, cannot be repaired, and the tooth needs to be removed.

How much does a tooth pin cost?

In the US private market, a post and core build-up commonly runs about $250–$600, with the crown on top adding roughly $900–$2,000 depending on material. A completed post and core crown therefore typically lands between about $1,200 and $2,500. Insurance often covers part of both components.

Can any tooth get a post?

No. The root has to be intact, of sufficient length and thickness, and free of vertical fracture, and the root canal filling has to be sound. Roots that are very short, strongly curved, or decayed below the bone level are not suitable, and replacing the tooth is then the more reliable option.
