The "Did you know" thread.....

I was told by a dentist that if you live in an area with fluoride in the water then you don't need to use toothpaste.

Hair (the follicles - hair is dead) produces natural oils that keep the hair clean. But if you stop shampooing it'll take weeks before it gets back to a natural smell-free state, during which time you'll get a lot of dirty looks. Too much for most of us to go through.

That's right. You need a lens for that.

Sorry, bad grammar. You need a Len for that.

Ah, no, they don't. One of the ways archaeologists and anthropologists determine age of some skeletons is by how worn and damaged the teeth are.

True, but that's natural. The point is that almost none are decayed in the way that processed food and sugar do it. They had no need for the crowns, bridges, fillings and dentures that you'd find in today's people

Did you know that the late Anna Wing(Lou Beale) actress in Eastenders's son was Mark Wing-Davey(she married a man called Peter Davey) who is more famous as Zaphod Beeblebrox in 'The Hitchhikers' Guide to the Galaxy', the BBC series of the early 80s...no, neither did I until today.

Did you know... Jack Black got his first acting job as a teenager in a commercial for the classic Atari game Pitfall. And his parents were nudists.

No, one of the big killers of early man was dental problems. Cavities that reach the root, get infected and the infection gets into the blood stream and kills them. Abscesses, same thing; broken teeth, etc. Don't give me *bleep* about how early man had perfect or even great teeth, he didn't by a LONG shot.

Some info on dentures:

A Brief History of Dentures

When we think of dentures, we generally think of something that looks like a standard set of teeth -- pearly white and attached to a pair of gums. But dentures weren't always as impressive or as attractive as they are today. Like all of dentistry and medicine, they have a long and colorful history.

The first dentures: Made from real teeth. The oldest false teeth were probably made from animal teeth. One 4,500-year-old man was discovered by archaeologists with his teeth ground down and likely replaced. This was done ceremonially and not for medical purposes, but the intent was the same. By 700 years BC, the ancient Etruscans were wearing dentures made of both human and animal teeth.

Ancient Japan. The Ganjyoyi Temple in Kii Province is home to a set of wooden dentures made from a littleleaf box tree. What's fascinating about these is that they used the same suction-adhesion method as modern dentures.

George Washington's famous false teeth. The first president started losing his teeth in his 20s, and so had them replaced early in life. In 2005, scientists discovered these teeth were not made of wood as previously believed, but a combination of gold, lead and ivory, as well as real teeth -- from humans, horses and donkeys. But those weren't the only animal teeth Washington had in his mouth; the ivory in the dentures likely came from a hippopotamus, an elephant or a walrus.

The introduction of porcelain. Alexis Duchateau is generally credited with the invention of porcelain dentures in 1770, using tiny springs to fasten the teeth to the base. After this, another dental engineer named Claudius Ash began making high-quality porcelain dentures, affixing them to 18-carat gold pates. He used plaster to make molds of his patients' mouths, and by the 1850s the practice had become common.

A History of Dentures

The precursors to modern dentures have a surprisingly vast history, with the first evidence of them being used by humans dating back to about 6500 years ago.
...
In June of 2006, archaeologists in Mexico discovered the skeleton of a 4500 year old man. These archaeologists were shocked to realize that this ancient human may have actually been wearing a set of ceremonial dentures at the time of his death; the oldest false teeth yet discovered. Now, the scientists didn't actually find the dentures themselves; but there was strong evidence to this fact in that the man’s front teeth appear to have been ground down for some reason, which led them to believe that this must have been done in order to make room for the fake teeth, which may have been some sort of animal teeth. Perhaps there are other good reasons to grind down one’s teeth, but paleontologists are rather certain that this is good evidence that false teeth have history much longer than previously suspected.

Still think ancient man had great teeth?
