How Do Whitening Toothpastes Work?
Whitening toothpastes scrub at the surface stains of your teeth. They are not effective against some types of stains, including those that are deep within the teeth. These toothpastes use different ingredients, not all of which are totally safe for your teeth for long-term use. We recommend that you speak with us about what type of whitening you desire and let us help get you the results you want most. For whitening toothpastes to work, they must be used at least twice a day and repeatedly for at least 4 weeks, so you should not expect quick results. Most of these products promise to show results within at least a month.
