About Crest Whitestrips Advanced Seals
Crest Whitestrips Advanced Seal is a timed programme of dental treatment strips that are designed to restore some of the natural whiteness on the surface of teeth - they come in 'upper' and 'lower' strips to ensure that they fit each section of the mouth in the most comfortable manner. It is recommended to apply them to teeth for 30 minutes per day, and many people are able to see the results after around three days of use, provided that the treatment guidelines are fully adhered to at all times.
When using these whitening products with the 'Advanced Seal' feature, it is possible to carry on with everyday activities while the treatment strips are in place. As it is recommended to apply them for periods of 30 minutes, this time can then be spent drinking water or talking - the strip stays in place during the course of regular use. Once the strip is in place, the material moulds itself to the exact shape of the individual's teeth, and this also ensures that as much of the treatment is applied as possible.
The formula of the strips includes a mixture of the same ingredients that are used by professional dentists and dental whitening specialists, and Crest has developed a way of getting the same benefits to home users. The product is designed to cover as much of the enamel as possible, meaning that users should notice that the whitening benefits can be seen closer to the gum line than with regular whitening products.
