Hydrogen peroxide or carbamide peroxide are typically used to whiten teeth. The United States Food and Drug Administration (FDA) only allows the term "bleaching" to be used when the treatment whitens teeth more than the teeth originally were. "Whitening" can be used to refer to anything that cleans the teeth of debris, including toothpaste. Manufacturers may use the term "whitening" even when the product is actually bleaching the teeth.
