What is the best teeth whitening system to use?

And how expensive is it?
--------------------
Teeth whitening methods range from the products for at-home use, such as toothpaste, strips, and even gel trays, to in-office treatments applied by dentists. They differ greatly in price, and also in effectiveness. In making a decision you should also consider the level of discoloration of your teeth. Care must be exercised to prevent damage to the teeth enamel. I suggest you read up a bit more and compare the different systems before making a decision.
