Maintenance is critical

The first couple of days after tooth whitening are the most critical. After whitening the pores or dentinal tubules are open and most susceptible to staining. I tell my patients to wait at least 36-48 hours to consume food or beverages that may stain teeth, those include anything that may stain a white T-shirt. All systems require maintenance with at-home trays that can be fabricated by your dentist. Consuming beverages that may stain teeth with a straw helps to keep your teeth sparkling!

In my experience, I tell patients to wait forty-eight hours. You would not want to go through all the effort of whitening your teeth and then discoloring them again.
