So I am back from my second dentist visit of the year. It was 2 hours long, and my mouth is numb from all the freeze they injected. I still have to go back just for cleaning. I am starting to feel that the tooth fairy hates me.
Anyway, while I was sitting on the dentist chair and trying to think about anything but the drill that was in my mouth, I imagined what would happen if our teeth can grow indefinitely all our lives (just like crocodile). If it hurts, we can just pull it out (gently, of course), and it will grow again. There will be no need for hygienist and dentist (or limited need for this profession as we know it now). No drilling in the teeth and no freezing anymore.
Instead, there might be field for teeth-polishing, teeth-coloring, and teeth-shaping. Much like what we have for our hair and nails.
Come to think of it.. I am so thankful that hair keeps on growing and nails grow back after we cut it. If I have to go through the drilling thing with my nails, I would absolutely go crazy. Aaaargghhh!!
