I think this toothbrush style scrubbing brush has to be one of the scariest items I've ever seen. Quite why the creator decided this brush should resemble the human mouth I don't know, but the addition of a gold tooth makes me wonder if it's a pirate that will be attacking your gnashers. It's $80 from Uncommon Goods, and they're handmade by blind people in Berlin. They use beech wood and perlon bristles which are good for cleaning dentures thoroughly, and you can also use them to clean the house. Ah, maybe they're not meant for the mouth then.
