Toothpaste

Toothpaste is a paste, powder or gel applied to the bristles of a toothbrush in order to help clean and maintain the aesthetics and health of teeth.

People who lived around the Mediterranean in the 5th millennium BC chewed a gummy substance called mastiche, derived from the resin of the mastic tree, which grew primarily in Greece and Turkey. They found it to be an effective tooth cleanser and breath freshener. 

The ancient Egyptians developed the first toothpaste, which was a crude mixture of powdered ashes of hooves of oxen, myrrh, powdered and burnt egg shells and pumice. They rubbed it on their teeth with their fingers.

A later toothpaste developed in Egypt was a mixture of iris flowers, mint leaves, pepper and powdered salt

The Roman toothpaste was mainly a more primitive, less tasty version using urine as a prime ingredient (the ammonia in it was an excellent cleaner). 

The ancient Chinese used baking soda or chalk as toothpastes.

Tooth powders for use with toothbrushes came into general use in the 19th century in Britain. Most were homemade, with chalk, pulverized brick, or salt as ingredients.

In New York City Colgate & Company became in 1873 the first company to market aromatic toothpaste in America. 

Originally toothpaste was sold in jars, then later metal tubes. In 1880, Doctor Washington Sheffield of New London, Connecticut introduced the first collapsible toothpaste tube, Dr. Sheffield's Creme Dentifrice. They were similar to the tubes that had just been introduced for artist's oil colors and Sheffield had the idea after his son traveled to Paris and saw painters using paint from tubes. 

Sixteen years later  Colgate & Company introduced its Dental Cream was packaged in collapsible tubes imitating Sheffield. 


FUN TOOTHPASTE FACTS

Colgate introduced a toothpaste in France called Cue, which was the name of a notorious pornographic magazine.

Toothpaste contains formaldehyde which is the same chemical used to preserve dead bodies.

Almost all major toothpaste brands contain sodium lauryl sulfate (also sodium dodecyl sulfate), an inexpensive lathering agent that is a known cause of canker sores. The sodium lauryl sulfate in toothpaste suppresses sweetness receptors, which is why orange juice and other juices taste so bad after brushing your teeth. In contrast, apples are known to taste more pleasant after using toothpaste. 

Toothpaste is sold in many brands.

The blob of toothpaste that sits on your toothbrush is called a "nurdle". 

In 2005, Zhonghua toothpaste unveiled the largest ever tube of toothpaste in Shanghai City, China. It was 9.7 ft long and weighed 1,719 lb.
