What causes discoloration of the teeth?
Teeth enamel discoloration can be caused by staining, ageing, or chemical damage to teeth. Some of the more common causes of teeth discoloration are medications, coffee, tea or cigarettes. People who drink significant amounts of cola soft drinks can experience similar staining.
Other genetic factors that can affect the colour of an individual's teeth. Some people just have naturally brighter enamel than others. On the other hand disease can also be a factor; fevers during childhood can affect mineralization of the teeth forming in the jaws often causing white spots. Certain medications e.g. tetracycline antibiotics are contraindicated in young children during tooth formation because of a tendency to stain developing teeth brown in colour. If you suspect that there is an underlying medical cause for your teeth discoloration, be sure to inform your cosmetic dentist.

Pros and Cons of Teeth Whitening
People typically have their teeth whitened to improve their appearance. Whiter teeth are associated with beauty and a healthier lifestyle. When people have a brighter smile, they tend to smile more often and are less self-conscious.
In addition, a whiter smile tends to minimize the appearance of facial wrinkles, giving way to a more youthful and energetic appearance.
Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.
Research indicates that bleaching is completely effective in more than 78% of people. Although bleaching is very effective, there can be short term disadvantages, such as sore gums or teeth from the bleach. This disappears when bleach use is discontinued. Some individuals are more chemically sensitive. If you are one of them, inform your cosmetic dentist so that you can be tested for sensitivity to the solution.
Bleaching will not affect the colour of crowns veneers and some other dental restorations, which may require replacement following the bleaching procedure.
In cases of serious teeth discoloration, bleaching may not be the best choice. Veneers or crowns may be the superior choice. Bleaching is usually the first solution to try due to its lower cost.
Some people experience discomfort from wearing the mouth tray. This typically goes away in short order, but if you suspect that there is a problem with the fit of your mouth tray, call your dentist's office. They can often make small adjustments that will minimize or eliminate the problem.
