Scientists Work Towards Growing New Teeth to Replace Fillings and Implants

London: Scientists are developing ways to help people regrow damaged teeth or even grow entirely new ones, raising hopes that future dental treatments could replace fillings, root canals and artificial implants with living tissue.

Researchers in the US and the UK are using stem cells, tooth-forming proteins and regenerative medicine to create "living fillings" that encourage teeth to repair themselves. Other teams are working on lab-grown teeth that could one day replace missing teeth with fully functional biological replacements.

Unlike conventional fillings and implants, which can wear out over time, regenerative treatments aim to restore the tooth's natural structure. Scientists say these approaches could preserve living tissue, reduce repeat dental procedures and improve long-term oral health.

The technology is still in the experimental stage and has not yet been tested in humans. Researchers say more laboratory and animal studies are needed before clinical trials can begin, meaning such treatments are still years away from becoming widely available.
