What makes your teeth whiter?

Tricky question ..: Regular toothpaste can make teeth 'whiter' by removing SURFACE stains (coffee, cigarettes, tea, etc). BUT 'teeth bleaching' is only possible with chemicals like hydrogen-peroxide or carbamide-peroxide; that are found in 'Crest Whitestrips' or in Dentists' office products!

Even if you maintain very good dental hygiene, food, environment, medications and aging effects may eventually lead to dental discoloration. If you are looking for more dramatic and sustainable results, your dentist may recommend in-office teeth whitening for you. This will allow them to use a stronger concentration of the whitening gel to break down tough stains and create a desirable white smile
