What are the best off the shelf products that can be used to whiten teeth and keep them white?

Teeth whitening: You can use over the counter products, however, they are not so effective and/or stable. OTC bleach and whitening tooth paste could be used as a supplement only. A professional teeth whitening without laser, followed by home whitening system with custom trays for the long term effect. You will be very happy with the results.

Crest White Strips: The Crest White Strips are well researched and proven by a very reputable company. There are toothpastes that specialize in removing proteins known to stain the teeth. These toothpastes include the Crest whitening toothpaste, Colgate whitening toothpaste, and Rembrandt toothpaste. There are others for sure, but I am not as familiar with them.

WhiteStrips: Crest's WhiteStrips brand of whitening products works well for many patients. Most whitening toothpastes work solely by abrasion and therefore are not particularly effective. Something like whitestrips that holds a whitening agent on the teeth for a period of time is most successful. Rinses also are not particularly effective
