Like many pharmaceutical products that used to be available only with a doctor’s prescription, a wide variety of teeth whitening products are now available for direct purchase by consumers. The category of OTC teeth whitening products include whitening toothpastes, whitening strips, rinses and brush-on formulas, and whitening kits that feature mouth trays and carbamide peroxide gels. OTC whitening products are widely available at drug, grocery and discount retailers, as well as hundreds of online resources.
IMPORTANT NOTE: The field of OTC whitening is not well regulated on the internet and one may purchase fraudulent or ineffective products from unknown manufacturers. It’s best to stick with names brands that you know.
