Toothpaste even though (in some form or another) has been around as long as the Ancient Greeks have, the formula (as we know it) did not become popular until World War I. As soon as companies began manufacturing toothpaste, people began to purchase the magical concoction - guaranteed to produce glistening teeth! White teeth were all the rage after World War I had ended, and toothpaste quickly became a product that most people simply couldn't live without.
Titanium Dioxide, This is another common toothpaste ingredient, though it's usually found in white paint. When added to toothpaste, titanium dioxide has the safe effect on your teeth as it does on walls - it keeps them nice and white (for a few hours, at least!). Ingesting titanium dioxide won't hurt you, but it isn't recommended either.
