No, teeth whitening can’t keep your smile white forever since it’s natural for teeth to discolor over time. While you can’t prevent future stains, there are specific lifestyle changes you can make to ensure your whitening treatment lasts:
Brushing your teeth at least twice a day
Flossing in between your gums daily and after meals
Avoiding foods and beverages that can stain your teeth
Your dentist will provide you with guidelines and instructions on what steps you should follow after your whitening procedure to ensure your smile continues to shine.
