Toothpaste was used as long ago as 500 BC in both China and India; however, modern toothpastes were developed in the 1800s. In 1824, a dentist named Peabody was the first person to add soap to toothpaste. John Harris first added chalk as an ingredient to toothpaste in the 1850s. In 1873, Colgate mass-produced the first toothpaste in a jar. In 1892, Dr. Washington Sheffield of Connecticut manufactured toothpaste into a collapsible tube. Sheffield's toothpaste was called Dr. Sheffield's Creme Dentifrice. In 1896, Colgate Dental Cream was packaged in collapsible tubes imitating Sheffield. Advancements in synthetic detergents made after WW II allowed for the replacement of the soap used in toothpaste with emulsifying agents such as Sodium Lauryl Sulphate and Sodium Ricinoleate. A few years later, Colgate started to add fluoride to toothpaste.

I never heard of chewing gum debates. You mean like whether kids should be allowed to chew gum in class? Try typing it in Google.

Bubble Wrap was created by two engineers, Alfred Fielding and Marc Chavannes, in 1957. Like many innovations, it was accidental: The two were trying to create a textured plastic wallpaper with paper backing that could be easily cleaned.\nit took me all of 3 seconds to find the answer to this

gum remains chewy, so your mind thinks it needs to keep chewing.  Food gets soft and your mind knows it's time to swallow.

Honestly, I don't know.  But here's my theory.  It used to be that Trident was one of the few sugarless gums available, so the ADA supported it.  Now there are a ton of sugarless gums, and maybe the ADA doesn't want to put their label on everyone of them.  Chewing sugarfree gum is a great way to cleanse the teeth of plague and food debris when brushing and flossing cannot be done.  Chew one with Xylitol.  Recent research proves that it prevents decay.

It's not true, gum is made up of both digestible sugars and indigestible carbohydrates called gums.\n\nThe indigestible part of chewing gum is passed through your body, just like fiber would be.\nThere also is no time lapse in the digestion process.  It goes through your body at the same pace as everything else.\n\nYou would be fine if you swallowed your gum!

Well, this is a much more difficult question.  There are many types of plastics, both natural and synthetic.  All plastics are organic materials, which means they are mainly made of carbon.  Because there are natural plastics, you can't really say when it was invented.  However, asking when the first plastics were produced in lab would probably be a better question.  New plastics are developed everyday.

It is not known who invented the first pencil. The pencil was first documented in 1565 by Conrad Gesner, and its invention is sometimes attributed to him, though this is unlikely. European craftsman (woodworkers) were the first known pencil manufacturers, and it wasn't until the late 1700's that manufacturing techniques similar to those practiced today were developed.

On March 10, 1876, in Boston, Massachusetts, Alexander Graham Bell invented the telephone. Thomas Watson fashioned the device itself; a crude thing made of a wooden stand, a funnel, a cup of acid, and some copper wire. But these simple parts and the equally simple first telephone call -- "Mr. Watson, come here, I want you!" -- belie a complicated past. Bell filed his application just hours before his competitor, Elisha Gray, filed notice to soon patent a telephone himself. What's more, though neither man had actually built a working telephone, Bell made his telephone operate three weeks later using ideas outlined in Gray's Notice of Invention, methods Bell did not propose in his own patent.
