How effective are whitening toothpastes and how do they work?
All toothpastes help remove surface stains through the action of mild abrasives. Whitening toothpastes can help remove surface stains only and do not contain bleach. Over-the-counter and professional whitening products contain hydrogen peroxide (a bleaching substance). No whitening toothpastes or over-the-counter bleaching product can come close to the bleaching effect you can get at your dentist’s office through chair-side bleaching. Whitening toothpastes and over-the counter bleaches can lighten your tooth’scolor by one shade. In contrast, light-activated whitening conducted in your dentist’s office can make your teeth three to eight shades lighter. Learn more about Zoom Whitening.
