Toothpaste is a paste or gel dentifrice used to clean and improve the aesthetic appearance and health of teeth.
It is almost always used in conjunction with a toothbrush. Toothpaste use can promote good oral hygiene: it can aid in the removal of dental plaque and food from the teeth, it can aid in the elimination and/or masking of halitosis, and it can deliver active ingredients such as fluoride to prevent tooth and gums (Gingiva) disease.
Most people in developed countries consider toothpaste a necessity and use it at least once a day.
The earliest known reference to a toothpaste is in a manuscript from Egypt in the 4th century A.D.
An 18th century American toothpaste recipe containing burnt bread has been found.
However, toothpaste or powders did not come into general use until the 19th century in Britain.
In the early 1800s, the toothbrush was usually used only with water, but tooth powders soon gained popularity.
Most were home made, with chalk, pulverized brick, and salt being common ingredients.
By 1900, a paste made of hydrogen peroxide and baking soda was recommended. Pre-mixed toothpastes were first marketed in the 19th century, but did not surpass the popularity of tooth-powder until World War I.
In New York City in 1896, Colgate & Company manufactured toothpaste in the first collapsible tube.
Fluoride was first added to toothpastes in 1914, and was criticized by the American Dental Association (ADA) in 1937.
Fluoride toothpastes developed in the 1950s received the ADA's approval. Countries limit and suggest different amounts acceptable for health.
