Why Can't We Transplant Teeth from One Person to Another? Is It Possible Within Your Own Mouth?

-

Wondering why tooth transplant between people isn’t possible like heart or kidney transplants? Discover why, and learn how tooth transplant within your own jaw actually works.

Introduction

If doctors can transplant hearts, kidneys, and even livers — why not teeth?

It’s a question many patients ask, especially when faced with tooth loss. The idea sounds simple: just take a healthy tooth from someone else and replace the one that's missing, right?

Unfortunately, it's not that simple. In this blog, we'll explain:

  • Why tooth transplants between people (allotransplantation) don’t work

  • Why tooth transplants within your own mouth (autotransplantation) actually can work

  • And what you should know if you're missing a tooth or need an extraction

Why You Can’t Transplant Teeth Between Two People

While organ transplants like kidneys and hearts work (with proper matching and medications), tooth transplantation between people is almost never done today. Here's why:

1. Your Body Will Reject Someone Else’s Tooth

Teeth contain live tissues — nerves, blood vessels, and the periodontal ligament. If a tooth from another person is placed in your mouth, your immune system will recognize it as "foreign" and likely attack or reject it.

2. Infection Risk

There's always the possibility of transmitting infections from one person to another, especially through live tissues like the pulp or ligament.

3. Difficult to Reconnect Nerves and Blood Supply

Even if the tooth is placed into your mouth, the blood vessels and nerves won’t naturally reconnect. This causes the tooth to die, leading to infection or failure.

4. Very Low Success Rates

While people have attempted this in the past, the success rate is extremely poor, and it’s no longer considered a viable treatment option in modern dentistry.

💡 Bottom line: Tooth transplants from another person don't work because of immune rejection, tissue death, and high risk of failure.

But Yes — You Can Transplant a Tooth Within Your Own Mouth!

This process is called autotransplantation — and it’s real, effective, and done in special cases by trained dental professionals.

 What Is Tooth Autotransplantation?

It’s the process of removing one of your own healthy teeth and placing it into a different spot in your mouth — usually where a tooth is missing or badly damaged.

 When Is It Done?

  • A molar or premolar is badly damaged or missing

  • You have a healthy wisdom tooth or premolar that’s not essential

  • There’s enough bone in the area receiving the transplanted tooth

  • You’re healthy, with no ongoing oral infections

 How It Works

  1. Your dentist or oral surgeon gently removes the donor tooth.

  2. The tooth is immediately placed into the new location.

  3. It’s secured (splinted) to allow healing.

  4. In some cases, a root canal is performed after placement.

  5. Regular follow-ups ensure healing and function.

Who Is a Good Candidate for Tooth Transplant Within Their Own Jaw?

  • Young patients with incomplete root formation (better healing)

  • People with wisdom teeth that are healthy but not functional

  • Patients who want to avoid implants or can’t afford one

  • Those with missing front teeth and available donor teeth

Is It Successful?

Yes — when done correctly, studies show tooth autotransplantation has success rates over 80–90%, especially in younger patients with healthy tissues.

🦷 Many dentists prefer autotransplantation in select cases, as it's biologically compatible, uses your own tissue, and has natural feel and function.

Risks or Limitations

Like all procedures, tooth autotransplantation has some risks:

  • The donor tooth might not survive the transfer

  • The root might break down

  • The tooth might fuse to the bone 

  • Requires careful timing and surgical skill

But under expert hands, it remains a fantastic option in many cases — especially when dental implants are not an option.

FAQs

1. Can I take a tooth from someone else and put it in my mouth?

No. Your immune system would reject it, and success is almost zero.

2. Can I move one of my own teeth to another spot?

Yes! That’s called tooth autotransplantation, and it works in the right cases.

3. Is it better than getting a dental implant?

It depends. If you have a good donor tooth and proper conditions, it's a great alternative.

4. Does the transplanted tooth need root canal treatment?

Sometimes — especially if the root is fully developed. Your dentist will decide.

5. Is it painful?

The procedure is done under anesthesia, and recovery is generally mild.

Final Thoughts

Tooth transplant between people? Not possible.
Tooth transplant within your own jaw? Absolutely — and with great success.

If you're missing a tooth, or have a damaged one, ask your dentist if tooth autotransplantation is right for you. In the right hands, it could give you back a natural, living tooth — without artificial replacements.
