you had said that polishing can only remove external stains. Then how do many dentists claim that teeths can be made whiter with laser treatment.

Ans: Hello
To whiten teeth one has to undergo a procedure called "bleaching". This is not the same as "polishing".
Polishing can only remove external stains. It cannot lighten the underlying natural colour.
Bleaching, on the other hand, is done with the help of chemicals (usually peroxide) which get activated upon exposure to laser (visible blue light). With this procedure it is possible to achieve noticeable whitening of teeth.
