Since the time of the ancient Egyptians, people have used mixtures of various substances in pursuit of a single goal: cleaning their teeth effectively. Today, even with a glut of toothpaste tubes on the supermarket shelf, most people seem to have a particular favorite. But have you ever thought about what's in your toothpaste, and how it works? Here are five facts you might not know.
1) Most toothpastes have a very similar set of active ingredients.
Once upon a time, a toothpaste might have contained crushed bones and oyster shells, pumice, or bark. Now, thankfully, they're a little different: today's toothpaste ingredients generally include abrasives, detergents and fluoride compounds, as well as inert substances like preservatives and binders. Toothpastes formulated to address special needs, like sensitive teeth or tartar prevention, have additional active ingredients.
2) Abrasives make the mechanical action of brushing more effective
These substances help remove stains and surface deposits from teeth. But don't even think about breaking out the sandpaper! Modern toothpastes use far gentler cleaning and polishing agents, like hydrated silica or alumina, calcium carbonate or dicalcium phosphate. These compounds are specially formulated to be effective without damaging tooth enamel.
3) Detergents help break up and wash away stains
The most common detergent in toothpaste (which is also found in many shampoos) is sodium lauryl sulfate, a substance that can be derived from coconut or palm kernel oil. Like the abrasives used in toothpaste, these detergents are far milder than the ones you use in the washing machine. Yet they're effective at loosening the stains clinging to your teeth, which would otherwise be hard to dissolve.
4) Fluoride helps prevent tooth decay
This has been conclusively demonstrated since it was first introduced into toothpaste formulations in 1914. Fluoride — whether it's in the form of sodium fluoride, stannous fluoride or sodium monofluorophosphate (MFP) — helps strengthen tooth enamel and make it more resistant to acid attack, which precipitates tooth decay. In fact, it's arguably the most important ingredient, and no toothpaste can receive the American Dental Association's Seal of Approval without it.
5) Look for toothpaste with the ADA seal
This means that the particular brand of toothpaste has proven effective as a cleaning agent and a preventative against tooth decay. Plus, if the package says it has other benefits, then research has verified that it does what it says. Oh, and one other thing — toothpaste doesn't work if you don't use it — so don't forget to brush regularly!

When asked about her dazzling white smile, Cat Cora, the first female iron chef on the hit television series Iron Chef America, freely admits to maintaining the brightness of her smile with professional whitening sessions.
“With what I do, whitening your teeth is like getting your hair done, your nails done and everything else you have to do to be on television,” Cat recently told Dear Doctor magazine. However, she does have her limits. “I want my teeth to be white and healthy looking — but not stark white or looking like they could glow in the dark,” she said with a laugh.
Cat's perceptions and experiences with tooth whitening may accurately describe Hollywood, but through the power of media, celebrities and their respective fan bases, having attractive white teeth has become a goal for most people. This is because white teeth are subconsciously associated with youth and virility.
Here in the dental office, we can use professional-strength “power bleaching” to whiten teeth several shades in a single visit. To prevent irritation to the area surrounding the teeth being treated, we isolate the gums and skin of the mouth with a protective gel or a rubber barrier known as a dental dam. After the whitening solution is placed on the teeth, the process may be supplemented by heat or a light source to activate or enhance peroxide release.
For bleaching teeth at home, our office can make custom-fitted bleaching trays that you fill with a gel form of carbamide peroxide. Sometimes this whitening gel can cause a temporary tooth sensitivity to hot and cold, but this normally lasts for no more than four days after you stop bleaching your teeth.
