"If you've always thought re-growing teeth was impossible, then you should realize that you simply believed what other people told you. Not only can you actually regrow teeth but you can even use your tooth root to repair chipped teeth, and even holes. No fillings needed.
I stumbled upon some fascinating information and technologies when I asked Google the question- "Why can't human beings regrow teeth" as I refused to believe we can't (because I did once and now know how, more on that below)"
