Front teeth, the 6 to 10 teeth are the most visible teeth when you talk or smile and these teeth are the ones that can benefit most from a laser tooth whitening, just as with the teeth at the back. If there are medium-to large-sized fillings in the teeth, it is probably better if these teeth were protected with crowns.
Most patients show great improvement after only one treatment. Since the protective biofilm that normally covers the tooth enamel is removed during the whitening procedure, you should avoid smoking and drinking pigmented liquids (coffee, tea, red wine) for about 24 hours after the whitening is completed.
If you have dental restorations (crowns, bonding), the plastics and porcelain will not change color. You may need to have some of those fillings redone once your teeth are lightened. We will let you know whether you can expect to have some fillings replaced due to the color change. If you are going to have fillings replaced, you should wait at least 2 weeks after the whitening is completed for the tooth color to stabilize before new restorations are placed. Some postoperative sensitivity is possible, but it usually disappears quickly. The tooth enamel or dentin is not damaged by the whitening process.
