Do Teeth Whitening Products Work?

How does teeth whitening work? Do at home teeth whitening products actually work? Everyone wants a brilliant white smile, but it can be hard to find the perfect teeth whitening product that will work best for you. Before choosing a method for teeth whitening, it’s important to understand what type of teeth whitening you’re looking for.

There are two kinds of teeth stains – intrinsic and extrinsic.
Extrinsic teeth stains are only on the outer layer or the surface of teeth. Intrinsic teeth stains are embedded in the tooth. Different kinds of teeth stains require different kinds of teeth whiteners.

Some teeth whiteners only polish the surface of teeth, removing extrinsic stains. Whitening products that contain hydrogen peroxide can get below the surface of your teeth for a brilliant white smile.
Colgate® Optic White® teeth whitening products contain hydrogen peroxide for the bright, beautiful smile you’ve always wanted.
