With the decreasing cost of bleaching products, many people want to brighten their smiles. However, these products do not work the same on all teeth. When you know more about whitening strips, you can decide if they are right for you.


A tooth whitening strip uses bleaching agents, such as peroxide, to remove stains from your teeth. They come in a variety of strengths and cost approximately $40 for a package that will last for two to four weeks.


Dentures are fake teeth, usually made of acrylic, that can stand in for a few teeth or for your entire row of teeth. They are usually constructed if you have lost permanent teeth.


Bleaching strips that you buy over the counter will not lighten discolored dentures, crowns, veneers, or other "fake" teeth. Strips are designed to be effective at whitening your natural teeth.


Fake teeth can stay true to their original color if you follow proper oral hygiene by brushing them twice a day, flossing, and using mouthwash. Avoid products that can easily stain your teeth, like red wine, berries, coffee and cigarettes.


If you have cared for your dentures properly but are displeased with the yellow or gray coloring they have taken on, discuss this with your dentist. It may be time for you to have your dentures replaced, and in a shade of white that suits your smile.
