I think 1 is more than enough despite the size of the polycule and keeps the counter looking tidy. What do you think?
Update: getting an electric tooth brush with our first fruits and getting a separate brush attachment for each of us that we can make a piece of pottery to hold super easy! Thanks for the input those that were helpful!
It is sometimes recommended that each person have TWO toothbrushes to ensure that it dries thoroughly between uses. You don’t want to be culturing your mouth bacteria on your toothbrush.
You also don’t all have the same mouth biome, because you likely have different oral hygiene habits, diets, etc. So no, you don’t want to share toothbrushes, those of you with less healthy oral biomes may be giving undesirable stuff to those of you with healthier ones.
