How is 1 MORE than enough? Is enough 0?

A polycule of n people should have at least n toothbrushes.

Do you fucking have a communal piece of dental floss that you all use too?

Am I going crazy? One toothbrush for every person. I'm a monogamuggle, and I don't even share a toothbrush regularly with my wife. If you insist on the counter being tidy, put them in a drawer. Also prevents aerosolized fecal matter from getting on the toothbrush head.

At what point? Always. What are you talking about?

Are you trolling?

Every mouth should have their own toothbrush, poly or not.

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.

Since I had zero clue:

In polyamory, a polycule is a group of individuals involved in romanticrelationships that connect all the members in the group.[1][2] It is not necessary for every individual of the polycule to be in a relationship with every other individual, and also not common.[3][4] The most simple and arguably most common polycule structure is a V shaped structure, a three-person polycule where one person is dating the two others, but the two others are not dating one another.

When you realize someone's also been using it to clean the toilet

There's no telling whether one or more partners might be a sink pisser, in which case your toothbrush could get accidentally peed on while you're none the wiser, so the best thing to do is not have a toothbrush at all and just use your finger

Ew

When you stop being single

Someone with "Lenin" in the nickname should not ask this question because it is obvious commies will confiscate all the toothbrushes.

whats a polycule?

If you replace yours after every use, then go for it!

If you keep a more traditional schedule of toothbrush replacement, I'd strongly suggest one brush per person per month. You might get away with one brush per 2 people per month, or one brush per person per up to 3 months, but not both.

My theory, this is someone deeply deluded who believes that they are multiple different people inhabiting one body. They have come into conflict within themselves of thinking that they are multiple people this requiring multiple toothbrushes and the reality of being one person who only needs one toothbrush.
