whitening toothpastes contain an abrasive agent that will remove accumulatation of caffeine and tobbacco stains, if used consistently.
Other than that, they will not whiten your teeth.
the concentration of peroxide in them is not efficient enough to produce any results.
As I said before, they're abrasive and should not be used by everyone, especially not if the enamel of your teeth is soft.
For the best results, you need to either get custom trays done by your dentist and use them with an at-home bleaching gel, or splurge for the newest laser/light techniques, whic are the most expensive, but the most efficient, giving you the highest percentage of peroxide.
Good luck!
