More and more people are considering teeth whitening as a way to improve their smile. They may have seen the positive results that it has had on a friend or a coworker and everyone knows that a whiter, brighter smile builds confidence and is a great way to begin feeling better about going into social situations.

For many people teeth whitening can help them in their business if they are working in sales or any other type of job that requires them to deal with the public on a daily basis. One thing that you should be aware of is that teeth whitening is not permanent but there are things that you can do and not do that can determine how long the effects last.

Having your teeth bleached is the simplest and cheapest way to whiten your teeth and many people are surprised to learn that no bleach is used in the process. It's a peroxide derivative that is used to whiten your teeth when you have them bleached. While there are kits that you can buy to whiten your teeth at home they can sometimes have limited results.

A dentist can tell by examining your teeth if you are a candidate that can benefit from bleaching as not all tooth discoloration problems can be cured by bleaching. Crowns and other dental work will only return to their original color when they are bleached, so if they were colored to match your teeth's original color you may have a problem.

Also, many times teeth in your mouth may vary in color somewhat and this means that you will have trouble getting them to match particularly if you are using a home kit. If you smoke or drink coffee or tea then you are a prime candidate for teeth whitening but you may also consider that these factors that originally caused your discoloration will again cause them to darken.
