How does teeth whitening work?

  • Share:

If you want a brilliant white smile, but aren't sure how to find a teeth whitening product that works, know that there are several whitening toothpastes that can whiten your teeth. The question is, which one is right for you?

Your teeth could have two possible types of stains. Extrinsic stains, on the outer layer of your teeth, or intrinsic stains, which are embedded in the tooth.

Just as there are different types of tooth stains, there are different types of teeth whiteners that can work for you.

Some whitening products contain mild abrasives that only polish the surface of your teeth, and only remove extrinsic stains. Other have hydrogen peroxide, an effective, professionally used whitening ingredient that gets below the surface, and safely whitens teeth inside and out, removing both extrinsic and intrinsic stains.

Before you choose any whitening product that works for you, be sure to look at the ingredients. Does your toothpaste contain hydrogen peroxide like Colgate® Optic White®?
