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.
All the duplications I know of were freak accidents that only happened because of some outside interference. A plasma storm, a spatial anomaly, an influx of chronitons… They barely even understand the cause half the time, and they’re not trying to recreate it because they already have pretty good cloning technology that they don’t need to use a transporter in a weird storm where they have the potential to be vaporized by lightning.

It seems like startrek lore has settled on multiple containment beams will duplicate people. It’s referenced multiple times. :) Even intentionally done under battlefield conditions… best Halloween party ever
