Dentifrice

Dentifrices, including toothpowder and toothpaste, are agents used along with a toothbrush to clean and polish natural teeth. They are supplied in paste, powder, gel or liquid form. There have been many dentifrices produced over the years, many focusing on marketing strategies to sell products, such as offering whitening capabilities. The most essential dentifrice recommended by dentists is toothpaste which is used in conjunction with a toothbrush to help remove food debris and dental plaque. Dentifrice is also the French word for toothpaste.

Toothpaste is a dentifrice used in conjunction with a toothbrush to help maintain oral hygiene. The essential components are an abrasive, binder, surfactant and humectant. Other ingredients are also used. The main purpose of the paste is to help remove debris and plaque with some marketed to serve accessory functions such as breath freshening and teeth whitening.

Tooth powder is an alternative to toothpaste. It comes in both a fluoride and non-fluoride version.

Tooth powder was generally used among the Romans, who used a variety of substances, such as the bones, hoofs, and horns of certain animals; crabs; egg-shells, and the shells of the oyster and the murex. They were reduced to a fine powder after having been previously burnt, and sometimes mixed with honey.

Ingredients that were sometimes added were ground myrrh, nitre and hartshorn. Tooth powder was used to clean and whiten teeth and to fix them when loose, to strengthen the gums, and to assuage toothache. Pounded pumice was a more dubious article, though Pliny the Elder says, "dentifrices, too, are prepared from it".

The earliest mention of tooth care among the Romans comes from a poem:

"Calpurnius, I greet you with some quick verse. I sent you, just as you asked me to, clean teeth and a bright smile, the product of Araby, a little powder, noble, fine and whitening, something to reduce the swelling of your little gums, to brush away yesterday's leftovers, so that nothing dingey and nasty might be seen should you part your lips in laughter."
