Every patient is different. If you are taking care of your teeth and are diligent in following directions, a Zoom teeth whitening treatment can last for one to two years. A lot also depends on the condition of your teeth before the whitening process begins.
During a consultation with your cosmetic dentist you can learn more about how you can make sure your Zoom teeth whitening lasts as long as possible.
While there are a variety of different home teeth whitening kits, none of them will work as well as in-office treatment performed by a certified professional. However, after you have had an in-office Zoom procedure, you should use a home teeth whitening kit to keep your teeth looking great.
The bottom line is home teeth whitening kits are not good as a primary solution, but they work great to help you maintain the professional in-office Zoom teeth whitening procedure.
