Toothpaste: A protector of tooth or bringer of harm
The development of toothpastes began in China and India during 300-500 BC. Initially, crushed bone, crushed egg and oyster shells were used as abrasives in tooth cleaning. Modern toothpastes were developed in the 1800s. Later, soap and chalk were added to their formulations and after Second World War soap was replaced with various chemical ingredients as abrasives, emulsifying agents, etc. In addition to 20–42% water, toothpastes are derived from a variety of components, including three main ones: abrasives, fluoride, and detergents. When it comes to toothpaste a lot of international as well as national brands compete in the market.
