White teeth - now that is something that we all want, but not all of can have. Or can we? Normally I would say no - not naturally at least - but since there are all kinds of products out there that are going to help a little bit, then it is a definite maybe.

Let's face it - our teeth aren't white even the day that we are born. The natural color ranges from yellowish brown all the way to greenish gray and it gets worse. The older you are the stronger is the color, no matter what you do and what you don't drink or eat.

Dental bleachers, or widely called teeth whiteners work by using different chemicals to remove pigment from your tooth enamel. This way they make your teeth look whiter, but it isn't that simple. The type of teeth you have to begin with, makes a difference in how well they will react to the bleaching process. If you have that brown shade to begin with, you are going to get better results, as gray teeth do not react to bleaches so well, and usually end up with no difference in the shade after a procedure is completed.

Normally these bleaches work great and leave no side effects or marks to your teeth, but when they are used on a regular basis they can cause some damage to the enamel, and this can cause a lot of pain - especially when you eat hot or cold foods.

The ingredients that are used in the best teeth whitening products are usually either carbamide peroxide or hydrogen peroxide. These are both very strong oxidants that simply change the structure of the molecules that cause the discoloration on your teeth, thus making it whiter. Using such bleaching agents it is even possible to go over the natural color of your teeth, and get an unnatural white color.

If you don't want to use a home bleaching kit, then I suggest that you go see a dentist and ask them what they think about teeth whitening products. Usually the answer is that there is no reason to do cosmetic work to perfectly good teeth, and that should you choose to get your teeth bleached anyways, it is a better idea to have it done at a dentsts, so that every proper precaution is made to avoid possible gum damage, and permanent damage to the enamel.
