The least expensive tooth whitening option is an over the counter (OTC) daily use product, such as toothbrushes, toothpaste or chewing gum. These products mechanically remove surface stains, provide temporary results, and usually only offer an improvement of one or two shades. In general, these tooth whitening methods do not make a dramatic difference, but may be useful to maintain professionally-whitened teeth.
