The first step in choosing a tooth whitening treatment is to evaluate the causes of tooth discoloration to determine the effectiveness of a whitening product, and which ones will provide the best results. To receive expert advice on your personal situation, it’s often a good idea to get the opinion of your dentist, even if you later decide on using an at-home, do-it-yourself whitening kit.

Getting Older
Often, teeth turning yellow is just a natural part of getting older. Even if you brush and floss regularly, over the years, stains can seep past the thin white film protecting your teeth and into the enamel. Toothpastes can’t reach this far, so although your teeth may still be strong and healthy, they may not provide the brightest smile.

Foods and Beverages
Teeth also darken because of the foods and drinks we consume. Some of the worst on your teeth include soda, tobacco, coffee, tea and berries because of the “chromogenic” agents in these products.

Accidents
If you have a single tooth that is dark due to a bumping accident or even a root canal, you’re probably suffering from an unhealthy nerve. In this case, you should get to the root of the problem and address the nerve and not simply try to whiten the outer film. Although whitening may temporarily whiten the outside, a tooth that sticks out like this deserves professional attention.

Many alternatives exist, from over the counter products to professional treatment options. When choosing among these alternatives, consider effectiveness, method, cost, and any possible risks. Consult an oral health care professional for individual recommendations.
The least expensive tooth whitening option is an over the counter (OTC) daily use product, such as toothbrushes, toothpaste or chewing gum. These products mechanically remove surface stains, provide temporary results, and usually only offer an improvement of one or two shades. In general, these tooth whitening methods do not make a dramatic difference, but may be useful to maintain professionally-whitened teeth.
Other over the counter products, such as tooth whitening strips and paint-on products, use a low concentration of a peroxide-based whitener. Still relatively inexpensive, this category of products can reduce age or diet-related staining and provide up to two shades of whitening. So, if limited results are sufficient for you, this is an economical alternative.
Tooth whitening products offered over television and the Internet should be used with caution. Some of the products in this category contain acid-based agents along with peroxide. The acidic products can damage the teeth and soft tissues. Also, because the trays used for some of these products are not custom-fitted, some users may swallow the whitening product.
Professional tooth whitening is available in two forms: in-office and at-home treatments. The in-office procedures are the most costly of all methods of tooth whitening and may require more than one visit. Peroxide agents are applied to the teeth either directly or in trays, and some use a laser, or light source, to accelerate the whitening process. The big advantage of this method of tooth whitening is the immediate result. This method can improve the smile five shades or more, but can also cause some temporary sensitivity.
Professionally supervised and dispensed tooth whitening products are effective on several types of stains. With this method, a dentist creates customized whitening trays for the user. The user then applies a thick peroxide based gel in the trays for at-home use. The results are very effective, up to six shades of improvement, but are gradual. Because of the regulation of product ingredients, the custom fitted trays, and professional supervision, this method is safer than similar products advertised on TV and the Internet.
Keep in mind that all products will only whiten natural teeth. If you have dental work in the front part of your mouth, see your oral health care professional for specific advice

As the market for these products grew, the Association recognized a need for uniform definitions when discussing whiteners.
For example, "whitening" is any process that will make teeth appear whiter. This can be achieved in two ways. A product can bleach the tooth, which means that it actually changes the natural tooth color. Bleaching products contain peroxide(s) that help remove deep (intrinsic) and surface (extrinsic) stains. By contrast, non-bleaching whitening products contain agents that work by physical or chemical action to help remove surface stains only.
