Not many westerners have heard of a bamboo charcoal toothbrush, it is an item which has been primarily used and understood in China. The colour of the bristles may actually put people off giving it a chance, as the dark musky black colour leads to the presumption that it can’t be good for your teeth. In fact, the opposite is true. Charcoal brushes have tons of benefits which cannot be replicated with modern plastic bristles, here is an article about such benefits.
The manufacturing process of the toothbrushes is somewhat fascinating. First bamboo charcoal must be created, this is done by taking 5+ year old bamboo and roasting in an oven at 800 to 1200 °C until the bamboo blackens. This charcoal is an environmentally functional material that has superb absorbing properties. This material is then broken down and infused onto the bamboo bristles of the toothbrush at a nano level.
The bristles are then sewn onto the toothbrush head and rounded off to help protect the gums from sharp edges, although more traditional brushes were left as is and over time the bristle ends would round off. The toothbrush head can be made out of any material: metal, plastic, wood, etc. In the modern day they are commonly made out of plastic, although the more traditional wooden/bamboo head and handles are making a comeback, especially in a time of environmental woe.
The CharBrush is an example of a bamboo charcoal toothbrush which brings together the best elements of the entire process. Other examples can be found commonly around Asia, but are very hard to come by in the western world. It seems to be an art which has gone over westerners heads.
