ToothpasteImage copyright: Jonathan Sayles The addition of flouride in toothpaste has been the most effective ingredient in the reduction of tooth decay. We might think toothpaste is a modern invention but the ancient Egyptians used a tooth powder almost 7000 years ago, however its ingredients of ox hooves, pumice and eggshells is probably different to modern recipes.... All you had to do was add a little moisture and the paste was ready to use. The truly first modern toothpaste in a tube was produced by Colgate in 1896, but it wasn`t until World War I that toothpaste became more popular than tooth powder.
