I would be thrilled if this were a thing in my lifetime. I don't have many problems, but the sense of security that i won't need to put a fake tooth in later in life sounds great. Of course I also wonder how much this will end up costing, but if it's just a shot I feel like it should cost less than a procedure to create molds and fake teeth and having them inserted right?
Edit: nevermind, after reading i see they need to grow the tooth outside your mouth then find a way to implant it still... sounds expensive lol.
