• Whitening mechanism: The mechanism of a particular tooth whitening toothpaste is very important, and it is something that you should be aware of. Some whitening toothpaste uses bleaching agents or chemicals as their whitening ingredients, while some use baking soda or silica. They all work in whitening your teeth, but some should be used carefully so that you don't damage your teeth.

• Part of a routine: Whitening toothpaste works well, as long as you are persistent in using it. It removes stains from the surface of your teeth and gives you the bright white teeth you crave for. Most whitening toothpaste are safe for daily use, but only for a short while. But if the toothpaste contains very strong abrasive, it may damage the enamel of your teeth.

• For sensitive teeth as well: If you use the right type of whitening toothpaste, your teeth will be stronger. And if you have sensitive teeth, be sure to use a whitening toothpaste that is suitable for you.

• ADA Seal of Acceptance: Check to see that any whitening toothpaste you want to buy is certified by the American Dental Association (ADA). You may not find the ADA seal on every whitening toothpaste you come across--but that doesn't mean that the product will be ineffective.

• Whitening method: Another thing you should look out for is the whitening method the toothpaste uses. Check the active ingredient that is listed on the back of the whitening toothpaste, such as hydrogen peroxide, baking soda, or silica. If the toothpaste has a high percentage of hydrogen peroxide, then note that it will work faster and better, while silica is for people with sensitive teeth.

• Always read the ingredients: If what you want is protection against cavities, then use toothpaste that contains fluoride. If you are allergic to anything, use toothpaste that won't irritate your gums.
