Tooth Brush yoga
I am so excited!! I have found a new toothbrush, no wait, THE toothbrush! WOOP! No really. This post is about toothbrushes.
Recently, after reading a little bitty about what really happens to our plastic when we recycle, I started feeling less phenomenally awesome about myself for simply recycling and wanting to "up" the green-o-meter. Continuing to buy "virgin" plastic and recycling it just isn't gonna cut it anymore.
Cutting out a toothbrush just isn't really an option for me, but all the "eco" friendly toothbrushes I have seen around Halifax/Yarmouth area just haven't cut it- the bristles look hard, the brush shape looks wonky- I have receding gums, I need to be careful!
Then... one fateful day at Pete's Frootique (yes, non-Haligonians out there, Halifax has a really cool store called Pete's Frootique; Pete is an actual person and yes, he sells fruits), my fiancé and I ventured into the "health" section.
| It looks like an ordinary toothbrush but closer examination reveals a rod that runs through the replaceable bristle head and into the handle.
The metal rod is the secret to this toothbrush. It’s made of a patented semiconductor material that when activated by light produces electrons that help to remove dental plaque and improve oral hygiene. When exposed to light (a fluorescent bathroom light, a plain light bulb or sunlight), the photosensitive titanium rod inside the toothbrush converts the light into negatively charged electrons .

The rod releases these ions, which blend with saliva to attract positive (hydrogen) ions from the acid in the dental plaque. The acid is then neutralised and the plaque is disintegrated - a scientific approach to a cleaner and healthier mouth! Toothpaste is not required as water (saliva) is the active ingredient - oral hygiene now becomes not only natural, but also economical.
The first toothbrush to resemble the modern toothbrush is believed to have been invented in China in the late 1400s,which used the stiff hairs from a hog's neck, attached to a bamboo stick.

Evolution and Analysis of the Toothbrush
Kylie W. Sembera's article, which appeared in the American Society of Mechanical Engineers Mechanical Advantage , discusses the history of the toothbrush with diagrams comparing classic style toothbrush designs with today's styles.
The bristle toothbrush, similar to the type used today, was not invented until 1498 in China. The bristles were actually the stiff, coarse hairs taken from the back of a hog's neck and attached to handles made of bone or bamboo.
Boar bristles were used until 1938, when nylon bristles were introduced by Dupont de Nemours. The first nylon toothbrush was called Doctor West's Miracle Toothbrush. Later, Americans were influenced by the disciplined hygiene habits of soldiers from World War II. They became increasingly concerned with the practice of good oral hygiene and quickly adopted the nylon toothbrush.
