How It Works
Tooth-whitening strips are an over-the-counter remedy that bleaches teeth for a whiter smile. As compared to other whitening methods, consumers prefer strips because they are easy to use, comfortable to wear and provide more consistent results. Individuals who use this product apply a thin strip of plastic to the front of both the upper and lower teeth. One side of the plastic is coated with a thin film of hydrogen peroxide; this is a bleaching agent. Once you place them across the teeth, you press the strips gently into place in order to get maximum contact. The strip is then kept on for a certain period of time that depending on the concentration of hydrogen peroxide within it. Strips are typically worn for 30 minutes, twice a day. Depending on the brand you purchase, you may use them for either 7 or 14 days.
There are two ways to whiten teeth, bleaching or oxidizing (removing stains by oxygenating tooth enamel). Tooth-whitening strips use the active ingredient hydrogen peroxide to bleach tooth enamel. While people who use whitening strips may see drastic results in just days, others may not notice any results at all. Tooth bleaching is not something that can work on all stains, especially with the bleaching agent contains a lower concentration of hydrogen peroxide. (This pertains to over-the-counter remedies.) In addition, whitening results may be drastic, but they will only be temporary. Stains caused by eating, drinking and smoking can quickly return the teeth to a dull color. Because of this, individuals who use whitening strips may have to repeat treatment several times a year in order to maintain consistent results.
Why To Choose Tooth Whitening Strips
Many men and women choose tooth-whitening-strips instead of other over-the-counter whitening remedies because of their ease and convenience. When strips are applied to the teeth, they are virtually invisible, thus allowing users to go about a normal daily activities. They also only need to be worn for 30 to 60 minutes a day–much less time than other over-the-counter agents. Bleaching agents that require application via a brush or a tray are more difficult for to use because they are inconvenient and inconsistent. Some products have to be worn overnight; this can disrupt sleep and cause the whitening results to be unpredictable. While white strips may be a bit more expensive, the end result is typically well worth it.
