It’s called the “White Diet”. After the treatment you cannot smoke or eat or drink anything but water for 1 hour. For the next 24 hours (preferably 48 if you can), you should abstain from enjoying any of the usual tooth-staining suspects (coffee, red wine, tea, colas, tobacco, and even citrus juices). We can tell you how you might be able to get away with drinking these beverages if you really must get your fix. A full set of after-care instructions are provided after the treatment concludes.
