Do Teeth Whitening Strips Work?

Strips are among several teeth-whitening options sold in stores today. Some patients do find benefit in whitening strips, but not all get the results they need. Here is how teeth-whitening strips work and how well they fulfill their purpose.

How Whitening Strips Work

Whitening strips are made of plastic and coated with small amounts of peroxides, the same chemicals used in professional teeth whitening. When the strips are placed over the teeth, they conform to the shapes and hold the peroxides in place so that bleaching can occur. Peroxide concentrations vary, with the strongest strips containing solutions of up to 10 percent.

Limitations and Risks

Like other teeth-whitening products, strips are designed for mild to moderate stains. The lack of a barrier separating the strips from the gums makes gum irritation a risk. Combined with the need to use the strips repeatedly for moderate stains, this can make the system impractical in some cases. Patients with severe stains are unlikely to get good results from strips.

The use of strips is best limited to mild stain removal and smile maintenance. When heavier stains are present, patients can benefit from visiting our Beverly Hills tooth whitening dentist instead. At a consultation with our dentist, you can learn more about how strips compare to professional whitening.
