Which Whitening Tooth Paste works the best?GrandviewDental | April 11, 2009
None. No matter what the marketing says, the so called whitening tooth pastes do not effectively whiten your teeth.
Why Not? Because your teeth get whiter based on how long the whitening active ingredient stays on your teeth. How long is the whitening toothpaste on your teeth before you rinse it off? Maybe 2 minutes and that isn’t long enough for any whitening ingredient to whiten your teeth.
Nowadays most toothpastes say they are whitening toothpastes but don’t think you teeth are going to get whiter using them. Use them for the taste/flavor and the cavity fighting properties and speak to your dentist or hygienist for more consistent ideas for whitening your smile.
