Japan pharma startup developing world-first drug to grow new teeth

Is there a possibility that these tooth growths happens in an undesired location, or is the drug administered in a way to ensure it only targets the desired location?

Wow ok, time to compete with alligators then.

Yyyesssss I've been following these startups for thirty years and want a viable regenerative tooth solution so bad.

Will they grow in hard to reach areas?
