Quote from @Marc Shin: Should i be providing disposable toothbrushes and extra toothpaste to guests? 

You can also leave out some bulk hotel toothbrush/toothpastes, make up removers, earplugs, sleeping masks, etc. if you really want to step up a "In Case You Forgot" basket.You can keep a closet with extra of things that has a lock on it and if someone is irrate because they don't have enough pods, you can at least have a back up solution for them if you choose too. 

Who knows, maybe you use that money and invest into a new type of toothpaste that blows any RE investment out of the water.

Check the cracks in the wall and see if there is filler or toothpaste.  

You can buff out scratches with a baking soda paste, a stainless steel scratch remover like Bar Keeper's Friend, or a small amount of toothpaste.

I’d argue that a mix of custom and arcane, broker-serving laws sustains current practice, not market demand like for Delta tickets or Colgate toothpaste.

I do some popcorn, Rice Krispies, sleeping masks, ear plugs, toothbrush /toothpaste, etc. local partnerships: find restaurants you may be able to get a discount for sending guests over for.

Laundry Machine soap, Dryer sheets, Bar of Soap, Shampoo, toothpaste, etc.

@Nathan G.Or the boyfriend bubba will squeeze the toothpaste out of your tube for ya.

If your hoping for repeat guests (where they pay full rate and you don’t have to share it with Airbnb or VRBO), then provide hotel size shampoo, conditioner, body wash, small toothbrush and small tube of tooth paste.
