Colgate Advanced Whitening Tartar Control Toothpaste with active microcleansing crystals for whiter teeth in 14 days. Colgate Advanced Whitening Tartar Control is a whitening toothpaste with MicroCleansing Crystals clinically proven to gently polish and effectively whiten your teeth. It fights plaque and cavities to ensure your teeth stay as healthy and strong as they are white. Tartar is a yellow mineral buildup that can dull the natural whiteness of your teeth. The fluoride formula contains ingredients to help prevent tartar from sticking to your teeth and effectively whiten your teeth, lifting off stains to give you whiter teeth in 14 days. While our teeth are not, by nature, perfectly white, most people feel that they could improve their smile with brighter, whiter teeth. Over time, teeth acquire surface stains as a result of eating and drinking certain foods and beverages. They also naturally discolour with age, as a result of acquiring pigmentation inside the teeth. There are various ways to safely remove the surface stains and the internal discolouration, leaving a whiter, more radiant smile.
