How long does the “whiteness” last?
With proper care and maintenance, these results can last up to five years with most patients. The use of a Rembrandt whitening toothpaste is required along with dental clean ups every six to twelve months, to ensure that the whitening lasts. However, if you fail to take care of your teeth by drinking large amounts of coffee, wine or any other staining ingredient, and continue to smoke, it is doubtful that the whitening will last for a lengthy period of time.
