After teeth whitening, it’s crucial to take special care of your teeth to maintain the results and avoid any potential staining. Here’s what you should do in the first 24 hours: Avoid Staining Foods and Drinks: Stay away from red wine, coffee, tea, dark sodas, tomato-based sauces, and berries like blueberries, as these can stain your teeth. No Smoking: Smoking can quickly stain your teeth, so avoid it for at least 24 hours after the procedure. Avoid Acidic and Colored Beverages: Beverages such as orange juice or sports drinks can also contribute to staining or tooth sensitivity after whitening. Brush and Rinse Gently: Use a soft-bristled toothbrush and a mild toothpaste to gently clean your teeth. Rinse with water or a non-colored mouthwash. Use a Straw: If you must drink anything other than water, consider using a straw to limit contact with your teeth. By following these guidelines, you can prolong the brightness of your newly whitened teeth.
