It blows my mind that, with all the scientific advancements humans have achieved, the best idea we have for keeping our teeth clean is "idk, have someone pick at them with metal spikes a couple times a year"
On a side note, a dentist in Japan discovered a way to regrow teeth. It's still a slow and beta'd process, with proven results in animals.
@lucifargundam That life is waaaay too macro for my tastes. I'd much prefer a mouthwash of bacteria or something that accomplishes the same thing instead of a big slimy worm rooting around in my mouth.
