Believe it or not, dental floss has probably been around for thousands of years. Researchers have discovered dental floss and toothpick grooves in the ancient teeth of prehistoric humans.

If you think about it, it makes sense. People have been getting food stuck in their teeth since the beginning of time!

It was not until the early 1800s, though, that flossing began to be recommended by a dentist. In 1819, New Orleans dentist Levi Spear Parmly published a book called A Practical Guide to the Management of the Teeth. He recommended that people floss with waxed silk thread "to dislodge that irritating matter which no brush can remove, and which is the real source of disease."

Although historians credit Parmly with the invention of modern dental floss, the first patent for dental floss was granted in 1874 to Asahel M. Shurtleff for "An Improved Pocket Thread Carrier and Cutter" that resembled modern floss packages. Shurtleff's company didn't begin to provide unwaxed silk floss for home use until 1882.

Unfortunately, dental floss didn't become popular right away. Professional dentistry was still a developing field, and silk thread was expensive.

It wasn't until after World War II, when Dr. Charles C. Bass created nylon floss as a substitute for silk floss. Then flossing became more common.

Today, dental floss is still made of nylon, as well as other types of plastic fibers. It comes in many varieties: flavored or unflavored, waxed or unwaxed.

Many people today use specialized plastic wands, called "floss picks," instead of traditional floss wrapped around their fingers!

The American Dental Association recommends flossing thoroughly at least once each day. Sadly, studies have revealed that only 10 percent to 40 percent of Americans floss daily.

According to dentists, flossing is a critical component of good dental health. Flossing (along with brushing) can prevent gum disease, cavities and bad breath.
