When choosing which toothpaste to buy, the most important thing you must look for is that it has the American Dental Association seal (ADA). The reason we recommend this is because that while the FDA does require manufacturers to meet certain guidelines, they do not test all of these products for compliance. The American Dental Association, however, does conduct extensive testing on the products to ensure that they meet these standards and are effective in their claims.
Typically, if you have braces or a retainer, there is not a special toothpaste that you have to use. However, it is important that you make sure to rinse regularly as food can get stuck in between the braces.
Find a cavity fighter. Fluoride is the only ingredient approved to fight cavities. You’ll see it listed as sodium fluoride, sodium monofluorophosphate, or stannous fluoride, and it helps enamel patch itself up before decay can lead to a cavity. Most pastes also have a base like baking soda to neutralize acids that rot teeth (that’s what fluoride- free ones rely on for protection).
For sensitive teeth: You’ll need a desensitizer, too. Arginine bicarbonate plugs the exposed pores in your teeth for immediate relief, while other ingredients, such as potassium nitrate and strontium chloride, block pain signals to the brain.
