People who have lost their teeth may now celebrate thanks to science's most recent medical advancement, which may one day allow for tooth regeneration. The Mainichi, Japan's national daily news site, recently revealed that a group of researchers there are now working on a medication that may be able to develop a new set of teeth and is also scheduled for a medical trial scheduled for July 2024."The idea of growing new teeth is every dentist's dream," said Dr. Katsu Takahashi, the study's principal investigator and the head of the dental and oral surgery division at the Medical Research Institute Kitano Hospital.

He said, "I've been working on this since I was a graduate student. "I was sure I could pull it off," the speaker said. Researchers anticipate that the revolutionary new medication, which treats those who lack a full set of adult teeth because of "congenital factors," will be accessible to the general public by 2030. If the research team is successful, the medicine will be the first in the world to enable patients to have their teeth regenerate. According to The New York Post, Takahashi has been performing this research at Kyoto University since around 2005 and has found that mice have a particular gene that impacts the growth of their teeth. Takahashi further explored the potential benefits of this gene's antibody, USAG-1, in a 2021 research published in Science Advances, can aid in stimulating tooth growth if it is suppressed.

Since then, scientists have sought to develop a drug that blocks USAG-1 called a "neutralising antibody." Mice and ferrets may grow new teeth under the right circumstances, according to research. The Cleveland Clinic claims that individuals who have anodontia, a rare genetic disease in which all teeth are absent because they never erupt, might benefit from the drug since they could have six or more missing teeth. The medication can help anodontic patients who lack adult or baby teeth. Takahashi aspires for the new medication to be just one more choice for people lacking a full set of teeth. "In any case, we’re hoping to see a time when tooth-regrowth medicine is a third choice alongside dentures and implants," Takahashi told the outlet.
