Was just thinking about this while taking a boring regular shower with water. A sonic shower just vibrates at high intensity to pulverize dirt and knock it from your body; but what about oils and lipids and all that other stuff that makes you stinky?
On a side note, I realized that the only time any dental care is brought up, it’s with the ferengi. The race with quite possibly the worst teeth in the galaxy are the only ones seen using cleaning utensils on them.
I assume the federation has a treatment that makes your mouth inhospitable to cavity-causing bacteria
hugh and stamets are both seen brushing their teeth in discovery. i imagine its just not shown very often
We are actually working on that now! There’s a sweetener called Xylitol that essentially starves bacteria to death because they can’t process it.
Edit: just found out it’s poisonous to dogs.
I could’ve sworn I read something a few years ago about some scientists genetically modifying or identifying this mutant variant of bacteria that was able to outcompete the natural stuff, but don’t produce the stuff that harms teeth. Was sometime in the 80s but the FDA completedly blackballed it.
