Most DIY products use peroxide to bleach discoloration and stains. Peroxide and other additional substances are actually very effective for whitening your teeth because it influences the outer layer of your teeth in all the right ways. You know that enamel - the outer most layer of the tooth surface - is actually semi-transparent; not white like what most people think. The layer beneath enamel is recognized as dentin, which is the primary source of your teeth's white color. Peroxide has the ability to penetrate enamel layer thoroughly without destroying the overall structure. It will then bleach the dentin layer to produce an overall whiter look.
The result of such process can vary, depending on the state of your teeth. You can use teeth color shade strips to help you determine the current state of your teeth. After the bleaching process, your teeth will generally look four shades brighter than before; this is why DIY products are known to produce instant results. After the process is done, you should continue with maintaining the current coloration of your teeth by using care products such as toothpaste or specially designed brush.
You can see the differences in a matter of minutes to hours, depending on the kind of teeth whitening product you are using. Make sure you read the instructions closely and that you know substances and composition used by the product before applying it to your teeth. You can never be too safe with teeth whitening products; certain precautions are necessary. Most of the available products are already tested and certified as safe for home or daily use as long as you follow the instructions.
