Smile-stones: A Teeth Cleaning Procedure Timeline

• The year was 1498 when the first "bristled" toothbrush came into existence in China.
  Its bristles were actually part of the back hair in the neck region of the famous Siberian hogs.
  Either Chinese bamboo or hollow bones were used as handles wherein these "bristles" were stuck.
  The wandering Europeans were the first to notice these and also the first to bring it into their own homeland.
  
• Many years past and many hog's hair have been lost already before this kind of material has been replaced with plastic.
  After nearly half a millennium of using hog's hair as tooth brush bristles, teeth whitening procedure had encountered a major change.
  Thanks to the Du Pont genius when nylon was discovered in 1938.
  Nylon became a popular substitute for the animal's hair but it was not until 1950 that soft nylon toothbrush bristles was introduced.
  
• After a short period of time, another enhancement was introduced, the more convenient and easy to use electronic toothbrush.
  It was electronically operated but it was later subdued by the more convenient battery operated one.
  It has a motor in it that cause its bristles to automatically have its up and down motion when switched-on.

Just be wise enough in choosing the best option available for you.
Who knows, these procedures and techniques may linger for another 3000 years, just like the lowly but mighty "chew sticks".
