Dentin Autografting: Using Your Own Tooth as a Bone Graft

By Dr. Scott Puckett, DDS · Updated September 2026

Dentin autografting turns your own extracted tooth into a bone graft. The tooth is cleaned and processed the same day, then placed back into the socket to preserve the jawbone after extraction. Because it’s your own tissue, there’s no donor or animal material — and studies show it preserves the ridge about as well as conventional grafts.

What is dentin autografting?

When a tooth comes out, the bone that surrounded it starts to shrink over the following months — a natural process called resorption. Left alone, an empty socket can lose a significant share of its width and height, which becomes a problem if you later want a dental implant, because an implant needs enough bone to anchor into. A bone graft placed in the socket at the time of extraction preserves that bone. Dentin autografting uses a surprising source for the graft: your own extracted tooth.

Most of the time, we prefer to use the patient’s own tooth — called dentin autografting — where we’re using the patient’s own tissue to regenerate bone within their body.

Why a tooth works as bone

It sounds unlikely until you look at what a tooth is made of. Dentin — the layer beneath the enamel that makes up most of the tooth — is remarkably similar in composition to bone: both are built largely from type-I collagen and a mineral called hydroxyapatite, and dentin also contains its own growth factors. Once a tooth is cleaned and processed into small granules, it behaves like a natural, biocompatible scaffold that your body can remodel into new bone.

How it’s done, step by step

The elegant part is that it all happens in one visit, using a tooth that would otherwise be discarded:

The tooth is extracted as it normally would be.
It’s cleaned of decay, fillings, and soft tissue, then ground into fine granules using a chairside device.
The granules are disinfected and processed (including a demineralizing step) to prepare them as graft material.
The prepared dentin graft is placed back into the socket, often together with PRF to further support healing.
The site heals over the following months, preserving the ridge for a future implant or restoration.

Because the graft comes from the tooth already being removed, there’s no second surgical site — unlike harvesting bone from elsewhere in the jaw or body.

Bone grafting options compared

There are four broad sources of grafting material. Dentin autografting belongs to the autograft category — the most biologically compatible, because it’s your own tissue:

Graft type	Source	Notes
Autograft (incl. dentin / your own tooth)	Your own tissue	No donor or animal material; highest biocompatibility; no rejection risk
Allograft	Human donor (cadaver) bone	Processed and sterilized; widely used and reliable
Xenograft	Animal (usually cow) bone	Widely used and well-studied; slow to resorb
Synthetic (alloplast)	Man-made materials	No biological source; consistent supply

Why holistically-minded patients choose it

For patients who want to minimize exposure to donor or animal tissue, using their own tooth is the natural choice — it sidesteps the concerns some people have about processed cadaver or cow-derived grafts entirely. It also appeals to anyone who likes the logic of using one part of their own body to rebuild another.

What the evidence shows

Dentin autografting is emerging but increasingly well-supported. A systematic review and meta-analysis found autogenous tooth grafts effectively preserve ridge dimensions after extraction, and randomized and histology studies back this up with hard numbers: in one analysis the graft limited ridge-width loss to well under a millimeter on average, biopsies showed roughly 40% newly-formed bone with only about 12% residual graft material remaining, and healing was uneventful. In plain terms: the tooth graft doesn’t just fill the space — it genuinely turns into new bone. Because the technique is newer than allografts or xenografts, very-long-term data is still accumulating, but the short-to-medium-term results are strong.

Dr. Puckett’s experience

Wilmington Oral Surgery has performed dentin autografting since 2022 in hundreds of patients of all ages, including people with complex medical histories.

The amount of bone regenerated has demonstrably been more significant than with human or cow bone, and the dentin autograft shows slower resorption over time.

That slower resorption matters: a graft that holds its volume longer gives a more stable foundation for an implant.

Limitations and who it’s not for

Dentin autografting isn’t an option in every case. The main limitations:

Root-canal-treated teeth generally can’t be used for the graft.
There must be enough tooth volume to produce a useful amount of graft material — sometimes a second tooth being removed is used to add volume.
As with any socket graft, active infection may need to be managed first.

Where it doesn’t apply, conventional grafts remain reliable, well-studied options.

Frequently Asked Questions

Does dentin autografting work as well as a regular bone graft?

The evidence is promising. Systematic reviews and randomized trials find autogenous dentin (tooth) grafts preserve the jaw ridge effectively after extraction — comparable to conventional grafts, with good new-bone formation. It’s an emerging technique with strong short-to-medium-term results.

Which teeth can be used for a dentin graft?

Usually the tooth being extracted, sometimes with another, provides the material. Teeth that have had root canals generally aren’t suitable, and there needs to be enough tooth volume to make a useful graft.

Is using my own tooth safe?

Yes. Because it’s your own tissue, there’s no donor or animal material and no risk of rejection or disease transmission. Dentin is chemically similar to bone, which is why it integrates well.

Does dentin autografting hurt or add a lot of time?

It’s done during the same appointment as your extraction. The tooth is processed chairside while you’re there, so it doesn’t require a separate surgery or donor site — which is one of its advantages over harvesting bone from elsewhere in your body.

How long does it take to heal before an implant?

As with other socket grafts, the site typically heals over roughly three to six months before an implant is placed, though your surgeon will confirm timing based on your healing and the location.

Is dentin autografting experimental?

It’s newer than allografts or xenografts but no longer experimental — it’s supported by published clinical trials and used routinely in some practices. Dr. Puckett has used it since 2022 in hundreds of patients.
