Because having whiter teeth has now become the number one aesthetic concern of most patients, there are a number of ways to whiten teeth, both in-office and from the comfort of your home.
One popular method is using an at-home teeth whitening system – provided by a dentist – that can whiten your teeth dramatically. This is because the whitening agents works to break down the proteins in tooth enamel that cause discoloration, lifting surface-level stains.
Unfortunately, the whitening process may not be as effective in removing intrinsic discoloration (more internal). This type of discoloration can be caused by certain medications and medical conditions, as well as tooth trauma.
Since teeth whitening only works on natural tooth enamel, it’s important to have a professional dentist evaluate replacement of any old fillings, crowns, and other dental work. Replacement of any restorations will be done after bleaching so they will match the newly bleached teeth.
Teeth whitening isn’t a permanent treatment. A touch-up maybe needed every few years or so, and more often if you smoke, drink coffee, tea, or wine.
