Your smile is often the first thing someone notices about you. But many things, including coffee, tea, red wine and tobacco, can stain them and cause them to darken. Here are answers to some of the questions we hear most often from people who want a brighter, whiter smile.
How does it work?
Teeth whitening products contain a peroxide-based bleach that breaks up both deep and surface stains in tooth enamel. The degree of whiteness that can be achieved will vary based on the condition of your teeth, how much staining you have, and the type of bleaching system you use.

Does it work on all teeth?
No. It’s important to talk with your dentist before deciding to make teeth whitening because whiteners may not correct all types of discoloration. Yellow teeth usually bleach well, brown teeth may not respond as well, and teeth with gray tones may not bleach at all. In addition, whitening will not work on veneers, crowns or fillings. And it won’t be effective on tooth discoloration caused by medications or injury to the tooth.
Can a person with very sensitive teeth have their teeth whitening?
In almost all cases, yes. A number of steps can be taken to address the issue of sensitivity:
- The strength of the bleaching solution as well as the length of time teeth are exposed to it can be adjusted.
- The length of time between treatments can be extended.
Be sure to discuss your sensitivity problem with your Miami Smile Dental dentist.
There are also things you can do to lessen sensitivity. Avoid foods that are very hot or very cold. Use a prescribed gel or toothpaste made for sensitive teeth along with a soft-bristle toothbrush. And try to avoid foods citrus fruits and foods that are highly acidic.

How long does it last?
Teeth whitening isn’t permanent. If you expose your teeth to foods and beverages that cause staining, whitening may start to fade in a little as a month. However, if you avoid those things that stain, you may be able to wait as long as a year before another treatment or touch-up is necessary.
