The day is not far when people who lose a tooth won’t need dental implants or fillings anymore. Scientists at King’s College London in the United Kingdom have developed a groundbreaking technology that enables human teeth to be successfully grown in laboratories.
The researchers have created a special biological material that provides a conducive environment for tooth development. This material helps cells communicate effectively with one another, initiating the process of tooth formation. Earlier attempts to grow teeth from cells had failed because the cells could not interact properly.
The Times of Mumbai spoke to Dr. Ashutosh Pandey, Consultant Dentist at DEZY Clinic, Mumbai, about the possibility of teeth regrowth. He explained that while research is ongoing—primarily on mice—it’s too early to comment on its effectiveness or challenges in humans, as the study is still underway. However, global efforts are being made in this field. Meanwhile, dental implant technology has advanced significantly, with materials like pure titanium, gold, bioceramics, and zirconia now available. With digital dentistry, doctors now can scan and map a patient’s teeth remotely, and plan treatments accurately without needing an in-person clinic visit, enhancing convenience and precision, added Dr. Pandey.
Inspired by Sharks and Elephants
Scientists drew inspiration from sharks and elephants—animals that naturally grow new teeth throughout their lives. They believe this may now be possible for humans as well.
Two Potential Methods Developed:
- Lab-Grown Transplants: Entire teeth can be cultivated in the lab and later implanted into the patient’s jaw.
- In-Mouth Cell Seeding: Tooth cells can be placed directly into the patient’s mouth, where the new tooth can grow naturally.
Why This Technology is Special:
Unlike conventional fillings and dental implants, which are not entirely natural and may weaken over time, this new method could offer a more permanent and organic solution. Traditional methods can lead to complications such as infections or loosening, but bioengineered teeth might eliminate such risks.
This innovation marks a major leap forward in regenerative dentistry and offers hope for millions suffering from tooth loss.
