After Using Crest Whitestrips, How Long Until I Can Eat Coloured Foods?

Most people do NOT restrict their diets totally while using the Whitestrips. It is crucial to do so for 24-48 hours after having an in-office bleaching such as ZOOM. However, if you use the Whitestrips at night, you should be OK with regular foods the next day. Needless to say, colored foods and liquids do stain teeth. So, the more restrictive you are, the less your teeth will stain in the future.

Hi there,
Typically after any sort of whitening, avoid organic stains such as coffee, tea, red wine, dark chocolate, turmeric, etc for 3-5 days. Even over the counter whitening products such as white strips can leave you vulnerable to post-treatment stain uptake. It's also a good idea to switch to an anti-sensitivity, high fluoride toothpaste for a month or two after whitening in order to help strengthen your teeth as well as help with potential post-whitening sensitivity which can occur in some cases. Overall, I'm not a big fan of over the counter whitening products because they yield more often than not poor results and compromise enamel due to overuse because they are so readily available. In office, professional whitening is still the gold standard. Good luck!

Drinking your tea through a straw will help but not totally block the staining tea.  Tea is the most staining then coffee, red wine, and dark soft drinks.
