How do whitening rinses work?

ANSWER

Like most mouthwashes, whitening rinses freshen breath and help reduce dental plaque and gum disease. That said, these products also include ingredients, such as hydrogen peroxide in some, which whiten teeth. Manufacturers say it may take 12 weeks to see results. You just swish them around in your mouth for 60 seconds twice a day before brushing your teeth. However, some experts say that rinses may not be as effective as other over-the-counter whitening products. Because a whitening rinse is only in contact with the teeth for such a short time -- just two minutes a day compared to 30 minutes for many strips -- it may have less of an effect.
