Because having whiter teeth has now become the number one aesthetic concern of most patients, there are a number of ways to whiten teeth. The most popular method is using a home teeth whitening system that will whiten teeth dramatically. Since teeth whitening only works on natural tooth enamel, it is important to evaluate replacement of any old fillings, crowns, etc. Replacement of any restorations will be done after bleaching so they will match the newly bleached teeth.
