As a dentist, we don’t specifically recommend that you use a whitening toothpaste in between treatments. These pastes can help to keep surface stains at bay in theory, but they are abrasive and can damage the root & gum surfaces. Believe it or not, only one ingredient is important to routine at home maintenance is a topical fluoride toothpaste to prevent tooth decay. In reality, you can brush with water & rinse with topical fluoride. Rinsing with Hydrogen Peroxide can maintain your tooth whitening over time, but it does not however, do a good job of whitening teeth the first go round. Whitening tooth pastes only work on the surface, and can be effective if your teeth are not properly clean at the start. In the long term a registered dental hygienist taking care of the build up around the roots of your teeth combined with peroxide whitening agents maintain a youthful smile the best.
