You can find many different whitening products that contain hydrogen peroxide, including over-the-counter toothpastes, whitening strips, and in-office treatments. As a review published in the Journal of Evidence-Based Dental Practice concludes, products containing hydrogen peroxide are considered safe and effective, so long as the manufacturer's instructions are closely followed. Keep in mind that the time it takes for a product to achieve its desired effects varies for different whitening methods, and some may only remove surface stains, as the ADA explains. This is why it's best to discuss your options and goals with your dentist.
Whether you are looking to reduce oral bacteria or make your teeth more sparkly white, an oxygenated toothpaste may be a good option for you. But first, ask your dentist for advice to ensure that you purchase the toothpaste that will be the most effective for your situation, and always look for a toothpaste with the ADA Seal of Acceptance.
