First toothpaste in history
The Egyptians were the first people to use a paste to clean their teeth around 5000 BC. But the first modern toothpaste was invented in 1824 by the dentist, Peabody. The first commercially produced toothpaste was sold in a jar in 1873.

Toothpastes mainly contain water, abrasives, including aluminum hydroxide, calcium hydrogen phosphates, calcium carbonate, silica, hydroxyapatite and fluoride.
