Scientists are growing real, living teeth in labs—not plastic molds, not metal implants. Actual human tissue that fuses with your jaw. This could end fillings, dentures, and even root canals.
What’s Happening
A team at King’s College London and Imperial College has built a scaffold. It helps human stem cells grow into full tooth structures. This is happening in labs now.
The scaffold mimics the process by which teeth form before birth. It pushes the stem cells to turn into enamel, dentin, and pulp. The teeth have roots. They grow in the right shape. They’re alive.
We currently use artificial parts, including crowns, implants, and dentures. They work, but they’re mechanical. They can fail. They don’t bond with your jaw like real teeth.
What Makes This Different
- Biocompatibility: These lab-grown teeth fuse with the jawbone like natural teeth.
- Cell Communication: The scaffold mimics embryonic tissue environments, helping cells interact correctly.
- Multiple Tissues: Enamel, dentin, and pulp form together, not just one layer.
- Reduced Rejection: Since these are grown from the patient’s own cells (in future applications), immune rejection is expected to be minimal.
The Research Process
- Take stem cells from pulp or reprogrammed skin cells.
- Seed them into a scaffold loaded with specific cues.
- Add growth factors that simulate the processes that occur during early tooth development.
- Wait several weeks. Cells become enamel- and dentin-producing types.
- Test for durability, immune response, and integration with jawbone.

Why Regrowing Teeth Could Replace Root Canals
Millions live with missing or damaged teeth:
- 1 in 4 adults over 65 have no natural teeth.
- Dental implants are costly and don’t work for everyone.
- Root canals weaken teeth long-term.
If this works in people, we might stop repairing teeth and start regrowing them.
Comparison of Tooth Replacement Options:
Method Material Longevity Integration with Bone Cost Estimate
Crowns/Bridges Ceramic/Metal 5–15 yrs No ₹5,000–₹25,000
Implants Titanium/Porcelain 10–20 yrs Yes (partial) ₹25,000–₹60,000
Lab-Grown Teeth Human Tissue TBD Yes (natural) TBD
Timeline
This is early research:
- 2025–2026: Animal trials.
- 2027–2028: Human trials.
- 2030: Possible clinic rollout.
What’s in the way:
- Regulatory approval.
- Cost and insurance questions.
- Training dentists in regenerative tech.
Who It Might Help
- People with trauma injuries.
- Older adults with full or partial tooth loss.
- Children born without certain teeth.
- Anyone unable to tolerate implants or bridges.
What to Watch Out For
- Still years away from commercial availability.
- Unknown long-term durability.
- High initial costs are likely.
What Dentists Should Expect
- Labs will partner more closely with dental clinics.
- Oral surgery may shift from installing to regenerating.
- Training may expand into stem cell biology and 3D tissue printing.
What It Means for You
This isn’t something to get next week. But it’s probably coming. If your dentist isn’t tracking these breakthroughs, they should be.
Expect a future where you don’t get a filling—you grow back your tooth.
What You Can Do Now
Ask your provider if they’re following regenerative dentistry. Follow ongoing studies. This tech isn’t hype—it’s building toward reality.
