Discover the truth about toothpaste.

        First, get the powder of ox hooves, some burnt eggshells , and pumice . Mix them together, take a small tree branch, and start brushing. No, it¡¦s not a witch¡¦s spell. That¡¦s what you would have done to clean your teeth if you were an Egyptian in 5000 BC or so. Over thousands of years, different cultures used different ingredients for their tooth powders and pastes, such as crushed tree bark, oyster shells, chalk, and charcoal. Charcoal is still a common ingredient for particular brands of toothpaste today.

        Starting from the 1800s, tooth powders were gradually replaced by the kind of toothpaste that we are familiar with. Early toothpaste included soap or chalk. Colgate, one of the most popular brands today, first sold toothpaste in jars in 1873. Later, it introduced its toothpaste in a tube that is similar to the modern one.






        Standard toothpaste today has advanced greatly beyond the earliest powders. Typical toothpaste has an abrasive agent to remove plaque, fluoride to make teeth stronger, and a foaming agent to spread the toothpaste for better cleaning effects. Let¡¦s be thankful we are past the point of brushing our teeth with strange ingredients.
