The "white diet" involves refraining from consuming foods and drinks that can stain the enamel of your teeth. This dietary regimen is particularly important immediately after a teeth-whitening procedure while the whitening gel remains active inside the teeth, which can last for up to 24 hours. Adhering to the "white diet" is crucial for achieving the desired whitening results and maintaining those changes. Here are some guidelines for the "white diet" in the days following a whitening procedure: Avoid products containing colorings. Refrain from smoking. Steer clear of overly hot or cold foods and drinks. Avoid using lipstick or lip gloss. Stay away from any foods or drinks that could stain a white shirt. Use toothpaste and mouthwash that are not colored. It's recommended to follow the "white diet" for at least two weeks after the teeth-whitening procedure to ensure the best and longest-lasting results and prevent teeth staining. Please note: If you consume foods or drinks that can stain your enamel, be sure to use MAGIC SMILE FOAM TOOTHPASTE to brush your teeth as soon as possible. This will help mitigate the staining effects and maintain the whitening results.
