Regarding the new teeth, I think there's actually already been progress on this. I'm struggling to dig up the article, but I distinctly remember reading that researchers had used stem cells to regrow enamel in a tooth, essentially eradicating the need for fillings. It hadn't been properly tested on multiple humans yet, but it was in the works and the scientists who were working on it were confident. It would be great if it were scaled up and then came to market. A small, but life-changing advancement.Part of Tsuji’s research also looks at regenerating or growing new teeth. Imagine if veneers were no longer the answer to tooth fall or decay. Instead of masking the problem, rebirthing the solution sounds better.
People want proper cures to things, that’s why temporary solutions like hair fibers albeit useful, are not the ultimate answer.
Good post, Jimothy.
