Crest is a brand of toothpaste made by Procter & Gamble in Germany and in the United States of America and sold worldwide. In many countries in Europe, such as Germany, Bulgaria, Serbia, Ukraine, Russia, Poland, Hungary and Romania, it is sold as Blend-A-Med, the name of an established Germantoothpaste acquired by P&G in 1987 (formerly Blendax GmbH, located in Mainz, Germany).
While toothpastes containing a fluoride as the active ingredient had already a long history. Crest was first introduced in the United States in 1955. At first it used stannous fluoride, marketed as “Fluoristan” (this was also the original brand name it was sold under—it was later changed from “Fluoristan” to “Crestwith Fluoristan”). The composition of the toothpaste had been developed by Drs. Muhler, Harry Day, and William H. Nebergall at Indiana University, and was patented by Nebergall.

TCP commercial from 1981
TCP is a mild antiseptic, produced in France by Laboratoires Chemineau in Vouvray and sold in the United Kingdom by Pfizer.
The brand name comes from its original chemical name, which was Trichlorophenylmethyliodosalicyl (not to be confused with Trichlorophenol, a common fungicide). Trichlorophenylmethyliodosalicyl was replaced as the active ingredient by a mixture of phenol and halogenated phenols in the 1950s. The liquid form of TCP is one of the most well-known brands of antiseptic in the UK, and its distinctive sweet, medicinal odour can be identified by many as the generic smell of antiseptic.
