Scientists are exploring a future in which damaged or missing teeth could be regenerated instead of replaced with artificial implants. Researchers in the US, UK and Japan are developing innovative treatments using stem cells, bioengineered tissues and experimental medicines to stimulate natural tooth growth.
Some teams have successfully created tooth-like structures in laboratories, while others are investigating ways to repair enamel and dentine using living cells.
In Japan, researchers are also testing a drug designed to encourage tooth development by targeting a protein that normally suppresses it.
These advances could eventually transform dentistry, offering biological alternatives to fillings, dentures and implants. However, experts caution that the technology remains experimental, and no treatment capable of regrowing complete human teeth is currently available to the public.
Although significant challenges remain, regenerative dentistry could change how future generations approach tooth loss and oral health.
