I don't think tooth washing can solve it. Tooth washing can only wash away calculus, plaque and pigment in the mouth, so that the teeth will look whiter, but tooth washing only shows the color of your teeth, not "washing" your teeth.

This requires that teeth are not whitened by tooth whitening technology. There are many ways to whiten teeth, such as tooth whitening, blue light whitening and so on.

It is possible to repair broken teeth after tooth whitening. Look at your photos and just fill your teeth.
