I need to know how do you use crest whitening toothpaste?

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.

Whitening toothpaste: Use a pea sized portion, no more. Brush 2 full minutes by the clock 2x/day. Don't forget to floss daily. Whitening toothpastes are more abrasive, so discuss duration of use, and alternative whitening procedures, with your Dentist.
