Teeth whitening uses active ingredients to temporarily open up your teeth's pores, allowing the bleaching agent to absorb better and remove stains. After the procedure, your teeth's pores remain open for a couple of days, making them more prone to staining from food and drinks.That's why we suggest avoiding foods and beverages that can stain your teeth for 48 hours after your treatment.
Remember, anything that can stain your shirt can stain your teeth. Try to stay away from coffee, tea, soda, berries, tobacco products, mustard, tomato sauce, and many others. Do not use colored toothpaste or mouthwash.
