toothpaste
Brushing one's teeth has, for hundreds of years, been a hygienic and social necessity. Removing the bacterial biofilm, or plaque, that builds up on clean teeth every 12 to 24 hours helps prevent tooth decay, gum disease, and bad breath. None of us would think of leaving the house before brushing with a favorite toothpaste — unless, of course, we ran out. Then we would make a beeline for the nearest drug store rather than improvise for even one brushing! But what's in this substance we put in our mouths several times a day? And can toothpastes really do what they claim to do?
Abrasives
One of the main points of using toothpaste is to make the mechanical action of brushing more effective. In order to scrub off stains, you need a substance with a little graininess. This has been understood since ancient times; Egyptians scrubbed their teeth with a mixture of ox-hoof ashes, burnt eggshells and pumice as far back as 5000 BC. Ancient Romans used an even rougher blend of crushed bones and oyster shells, plus powdered charcoal and bark. Even in the 18th century AD, the British were including brick dust and crushed China in their toothpowder recipes.
Detergents
Your toothpaste foams because it contains a detergent, another type of cleaning ingredient. The purpose of a detergent is to loosen and break down substances on your teeth that would otherwise not be soluble, meaning they could not be dissolved and rinsed away with water. Although we might associate the word “detergent” with harsher cleaning products, detergents in toothpastes are mild so as not to irritate sensitive oral tissues.
Detergents are also known as “surfactants,” short for surface active agents. They are able to break through the tension at the surface of a liquid. Surface tension is the property that makes a fluid appear as if it has a skin — noticeable when dust or even denser materials settle or float on it. The way soap breaks down grease is an example of surfactant action.
The most common detergent/surfactant in toothpaste is sodium lauryl sulfate. You may have noticed it in other beauty products that foam, such as shampoo. This ingredient can be derived from coconut or palm kernel oil. While there have been internet rumors that sodium lauryl sulfate is dangerous, these claims are unsubstantiated by scientific research. This detergent has actually been used safely in toothpaste for more than 50 years. One credible concern, according to the Journal of the American Dental Association, is increased oral irritation in people prone to canker sores. These individuals should be aware that it is possible to buy toothpaste without sodium lauryl sulfate.
