It is best to avoid any staining foods and drinks immediately after Zoom in office whitening and over the 3 days following treatment. This includes Coffee, Tea and Red wine, as well as, tobacco and nicotine. I tell my patients to avoid any foods that would be difficult to remove from a spill on a white rug for 3 days following treatment. This is becuase the teeth are willing and able to re hydrate and pick up stains from ordinary every day foods at a quicker rate over the first few hours and will continue to be more permeable to stains for up to 3 days.In addition, a maintenance system should be set up by your doctor to keep those pearly whites as white and bright as possible. This may include at home custom made bleaching trays, maintenance gels and/or whitening pens and rinses.In office whitening is a great way to see immediate results for an event, holiday or party and it is a great way to start the process of whiter teeth, this is beacuse it will give optimal shades of whiteness in the shortest amount of time, however, keeping the results attained from Zoom!, just like everything else in cosmetics and beauty takes maintenance and additional time and treatments.
