If you think brushing your teeth with ground up ox hooves or egg shells sounds gross, consider that the ancient Egyptians didn’t have a drug store to buy a tube of Crest and an Oral B Toothbrush. In fact, the idea of daily tooth brushing didn’t really take off in the US until the troops came home from WWII. They brought home that helpful, hygiene habit. Other early historical teeth cleaning technologies include the Roman’s using frayed sticks and the Chinese configuring rudimentary brushes out of stiff animal bristles and ivory or bamboo handles. While William Addis is credited as the inventor of the toothbrush, in 1780, archeological records show the Chinese started using toothbrushes much earlier. So, when you’re considering skipping that ever so important hygiene habit, remember toothbrushes and minty fresh toothpaste are a pretty modern invention. We should all be glad we’re still not brushing our teeth using ground up ox hooves and frayed wooden sticks.
