Anyway, rags were hard work and they couldn't reach the narrow crannies between the teeth at the back of the mouth, and so a better alternative was in need, leading to the hero of our story:
a merchant named William Addis.
Addis was once involved in a riot and subsequently locked up in jail for a short spell of time.
Days felt inordinately long in his dark, damp cell, and his mind was constantly swirling around to figure out a way to relieve the foul taste in his mouth.
One swift glance at a broom outside his cell was just what he needed for an epiphany.
He searched about and located a bone in his cell, and managed to bore holes into it. (The prison at that time wasn't a pretty sight. It is entirely conceivable that the floor was overflowing with bones and pointy objects).
He then stuck the animal hairs he got from some kind-hearted and easily persuadable prison guard into the holes, and there it was: a makeshift but serviceable toothbrush.
Upon being released, he immediately put his idea to work and founded the toothbrush manufacturing company that is still active today: Wisdom Toothbrush.
It took another fifty years before an American man, H.N. Wadsworth, refined its design and filed a patent for his design.
Wadsworth's toothbrush was particularly mindful of our dental structure.
He meticulously elaborated in his design draft how every curve and arc of his brush catered to the forms of our teeth and mouths.
Then it wasn't until 1935 when artificial bristles took the place of animal hairs as the operative component of a toothbrush.
More decades passed before the majority of people finally got onboard with the tooth-brushing habit.
Layers upon layers of stories have gone into the history of this little device.
It almost seemed as if a large chunk of human history could be collapsed into the quest for the right toothbrush.
