Crest United States
In the history of human cosmetic dentistry, the use of peroxide to whiten teeth has a long history. The application of whitening strips is the result of people's continuous improvement and exploration of simple and effective methods of teeth bleaching. So far, the leading brand of whitening strips is Crest, a subsidiary of Procter & Gamble, and its teeth whitening products are the only one certified by the American Dental Association (ADA) for home whitening strips, which has won many international awards such as COSMO Annual Healthy Dental Strips, and is the vane of global home strips. Crest Dental Strips has a rich product line, including professional effects, gentle routine, classic vivid, and 1-Hour Express. At present, Crest has different product lines in different countries, but they are all made in the United States, as long as they are purchased through formal channels. Crest Dental Strips use hydrogen peroxide as an effective whitening ingredient for bleaching, with concentrations ranging from 5-10%, all in the form of PVP film patches. For healthy teeth, the most secure and effective product is Professional Effects, which can stretch more than other styles.
