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!
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.
That’s what big tooth brush wants you to think. If you use mouth wash after you brush, like you are supposed to, it sanitizes your whole mouth.
