Please help! what is the best teeth whitening toothpaste?

Depends on you...: Best here depends on personal preference for flavor, texture and sensitivity. Sometimes the answer is none at all, but odds are the polishing paste you dentist uses at your cleaning appointments tops them all.

Whitening toothpaste: All whitening toothpastes rely on being more abrasive to remove superficial stains from coffee, tea, cigarette smoke etc. They do not contain any whitening ingredients.While they may help initially, continued use can make the teeth darker as the outer lighter color is worn away revealing the darker inner structure. Also may make them more sensitive.
