However, before you can begin use of this product, there is one requirement that you need to fulfill. You need to make certain that you are brushing at least two times a day, or you will not get the results that you are looking for.
The first step in answering "How do Crest White Strips work?" is knowing the base theory on the product. By stripping away a thin layering of the enamel on your teeth and bleaching it, you can get a whiter smile. This is the basis for these products, and this is why there are side effects of teeth whiteners that you should be aware of. As there are abrasive chemicals and compounds, your teeth and gums are both agitated and affected by making use of them. Therefor cold and heat effects on bleaching teeth are more severe, as your teeth have become more sensitive due to the chemicals involved in the process.
On a more complicated level, answering how do Crest Whitestrips work and "Is this process safe?" requires a lot more thought. In very small doses, between brushing and use of the product, your teeth and gums are rendered very vulnerable to problems and cancer. On account of this, you should make certain you are very careful before you make a purchase and begin use of these products.
