Not all whitening products work and are appropriate for everyone. If the reason that teeth are stained is because of improper home care of your mouth and teeth, whitening will not work.
Here are daily habits that can help ensure your teeth don’t darken as a result of inadequate oral hygiene. When you don’t regularly brush, floss and rinse to reduce food particles, bacteria and debris from your mouth, these can turn into stain-making substances that darken the teeth. Follow these steps every day to prevent hygiene-related stains on your teeth.
At least twice daily, using a toothpaste that contains fluoride.
At least once a day, to clean hard-to-reach areas between teeth.
Using an antimicrobial mouthwash like Listerine® Total Care Teeth Protect Milder Taste Mouthwash rinse for 30 seconds twice a day.
