A team of researchers in Kansai is set to begin clinical trials next month to develop medicine to help grow teeth.
The researchers, including from Kitano Hospital and Kyoto University Hospital, will conduct trials for teething medicine, aimed at treating people with congenital anodontia who are born with few teeth.
To check its safety, the experimental drug will first be administered to adult men who have lost back teeth, before it is tested on children with congenital anodontia. The team aims to put the treatment into practical use in around 2030.
The context and explanation of everything else in the article in everything but that one cavity paragraph explains what it can treat and how it does it. Then that one paragraph says it may be used. In full context of the entire article (which is trash) it can be interpreted as not really for cavity missing teeth.
