About forty-eight hours after exposure to teeth whitening gel, the surface thereof is predisposed to stain again because the enamel pores are opened by the action of the gel, which is why you should be aware of what you take you to the mouth in the hours following the completion of tooth whitening because it would be a shame to return the teeth to stain after the investment in both time and money.

But if you’re a regular consumer of red wine I advise change you white wine for the following days after bleaching. If you usually drink coffee or tea, it would be better to replace milk or water, as these are neutral and minimize the possibility of staining the enamel again.
