Could dentists one day help you regrow your own teeth?

Imagine a dental visit where instead of dentures or implants, your dentist could help you regrow a brand-new tooth.
For millions of older adults, tooth loss has long meant living with removable dentures or permanent implants—but both come with downsides.
Dentures can slip or irritate, while implants are fixed and lack the natural feel of a living tooth.
Now, scientists are exploring something once thought impossible: regenerating teeth that look, feel, and function just like the originals.
While the research is still in early stages, the possibility of “tooth regeneration” is drawing closer—and it could transform the future of dental care.
Tooth loss is common, especially later in life.
In the US, about 178 million people are missing at least one tooth, and nearly one-quarter of adults over 60 have lost all of them.
Dentures remain a standard option, but they can cause discomfort and make eating challenging.
Dental implants are more stable but still artificial—they lack sensation and may contribute to bone loss over time.
The hope of regrowing real, living teeth offers an alternative that could solve these long-standing problems.
Researchers like Dr. Pamela C. Yelick at Tufts University are testing two approaches:
1. The scaffold method
Scientists create a tooth-shaped scaffold seeded with special cells that can grow into tooth-like tissue, including the periodontal ligament.
This ligament is what gives natural teeth their flexibility and unique sensation, something implants don’t have.
In animal studies, these lab-grown teeth integrated with the jaw and began functioning like real teeth.
2. The “switch on” method
Instead of building a tooth from scratch, researchers are studying ways to activate natural genetic signals in the body.
By blocking a protein called USAG-1, scientists have triggered the growth of new teeth in adult animals.
Human trials using an antibody therapy are being prepared, with an initial focus on children born without certain teeth.
While implants have improved life for many, living teeth could offer benefits that artificial solutions can’t:
Tooth regeneration isn’t available yet.
Scientists must refine how to source the right cells, ensure safety, and keep costs manageable.
There’s also the hurdle of teaching adult cells how to “remember” the process of forming a tooth.
But progress is accelerating, and new research tools like a detailed atlas of human tooth development are helping guide the work forward.
For older adults worried about dentures or the long-term issues with implants, tooth regeneration could someday provide a natural, lasting solution.
While the science is not yet ready for dental offices, human trials may bring it within reach in the coming years.
Until then, regular brushing, flossing, and dental checkups remain the best way to protect the teeth you have.

Why living teeth could be better
While implants have improved life for many, living teeth could offer benefits that artificial solutions can’t:
- Natural sensation: Real teeth can detect texture and pressure, giving a fuller eating experience.
- Bone preservation: Living teeth stimulate the jawbone in ways implants cannot, supporting long-term bone health.
- Durability: Living teeth can repair themselves and potentially last a lifetime.
- Lower risk: A tooth made of living tissue integrates fully with the body, reducing infection risks.
