Toothpaste is an invention that doesn't seem to have a definite inventor or date. Something like it was known in ancient Egypt, that people used a paste made of a mixture of ash and powdered eggshell, which they rubbed on their teeth with their fingers. In 1873 the Colgate Company - the same one that makes toothpaste today - introduced Colgate Dental cream, which smelled and tasted much nicer than anything else used until then. Soon after this, people began to use toothbrushes instead of sticks or fingers, which made cleaning teeth much easier. However, most Americans didn't brush their teeth regularly until the 1940s, which American soldiers who had spent several years in Europe and learned the habit there, went home after the Second World War.
