If you're considering using a whitening toothpaste, look for a brand that has a seal of approval from a reputable dental organization — such as the American Dental Association Seal of Acceptance. This seal indicates that the toothpaste is effective at removing surface stains.
If you're not satisfied with the effect of whitening toothpaste, ask your dentist or dental hygienist about other tooth whitening options — such as over-the-counter or professional bleaching products.
