Do Teeth Whitening Systems Work?

General Effectiveness of Teeth Whitening Systems

Many people are skeptical about the effects of teeth whitening, but the truth is that whitening with Crest Whitestrips teeth whitening systems is enamel safe. Certain chemicals, such as peroxides, have proven abilities to bleach teeth below the tooth surface and remove stains. Retail teeth whitening systems work by applying a thin layer of these chemicals to the teeth for a period of time, usually ranging from minutes to hours. Effectiveness of these products varies depending on the concentration of the whitening agent, treatment time and the kinds of stains involved.

Generally, teeth accumulate stain under the surface overtime and become darker and more yellow with age. Using peroxide-containing whitening products such as Crest Whitestrips whitens age-related tooth staining. Teeth can also become stained from exposure to certain medications (such as tetracycline). It is still possible to whiten these green-gray stains, however it may take longer as whitening is generally more effective on yellow teeth. One-sentence capsule: Teeth whitening is a safe and effective process that bleaches teeth and removes stains and gives you a smile makeover.
