Surface or extrinsic stains are formed on the surface of your tooth enamel and are usually caused by the foods and drinks you consume. Intrinsic stains lie below your enamel and are tougher to lift. They can be caused by ageing, genetics, trauma, certain medications or medical conditions.

If you’re wondering how to make teeth whiter, you have a few options. Use a whitening toothpaste twice a day to remove surface stains and keep your teeth looking bright. If staining lies below your tooth enamel, you can try a teeth whitening treatment at your dentist.

Colgate charcoal whitening toothpaste is enamel-safe for use twice a day. It also contains fluoride to help protect your teeth from cavities, keep your enamel strong and your gums healthy.
