Most U.S. cities put flouride additives in their water if there isn't enough, and they treat water when there is too much flouride present. Often children in the U.S. public schools are given flouride treatments regularly.  \nIn general, I also think that "Europeans" are not as obsessed with having white teeth as Americans are.

Maybe because most Americans are so Fat now that they see everyone around them as normal. How funny! In America we have different categories of being classified as fat, kind of like how the Eskimos have different names for snow. Weird huh?\n\nYou have your:\n\noverweight/chubby/big boned person\n\nFat/Obese\n\nExtreme Obese\n\nMorbidly Obese (300 lbs and up)\n\nThis is so crazy!

It has something to do with the area they live in. Body types are based on climate, landscape, food, and way of life.  Like Eskimo's for an extreme example, they are short and chubby because their diet consist of mostly fish and to be short and fat gives you a smaller body area to keep you warm.  Where as in Africa the natives are tall and skinny giving them longer body area to keep them cool in hot climates.  These are extreme examples but the same applies to European white people, but it is not as noticeable because American white people come from Europe, but our features have changed over time because of food, climate and living conditions.  It all boils down to where people originated and evolved from.

I have always heard its because when they eat 3 meals a day the biggest meal is lunch, so their body burns off more fat throughout the day. whereas Americans usually eat bigger dinners and then go to sleep shortly after.  It actually makes sense.\nOh, yeah and you should be able to go to Oprahs web site and get the link for that book. just type in some key words, Im sure you'll find her.

its quite a healthy way to adopt actually..... eat apples, they have a natural agent that whitens teeth and cleans plaque and tartar.

English people all have bad teeth. Yes, it's believed to be true and we watch Coronation Street to prove it.

That's so ridiculous that it's almost funny. The truth is, the western diet (the way most folks eat in the US and Europe) is responsible for more disease including cancer, diabetes, hearth problems, etc. Rural Asian communities have practically non-existent occurrences of cancer, diabetes, etc. BECAUSE of their diet.

Sugar, although a good source of quick energy, is not a nutritional need for humans.\n\nHowever, many plants create sugars for their own use, and by eating those plants could early man have ingested sugar.\n\nTree sap is a resin (not sweet- even in sugar maples averages 2% sugar).  It would more likely have pulled their teeth out or cemented their mouths shut than made for good chewing.  Maple syrup wasn't made until the 1600's.  Gum is a latex derivative (not sweet), which WAS harnessed by ancient man, but by south american indians, and to make durable footwear, not for eating.  It runs in different channels in the tree and is completely chemically different than sap.

Well compared to a humans lifespan we are only baby's for a short period of time.  After a certain age we need stronger teeth(adult teeth) to help digest all of the harsher stuff we eat as adults for the rest of our lives.  Some individuals such as myself have been blessed with extra teeth (3rd) a condition called freakishly "shark teeth" (because shark have 3 sets) that are still in my gums waiting for me to loss the tooth above it to come up. I am over 20, lost a tooth recently and the 3rd one came up! Cool for me!

Because the rate of heart disease and diabetes is much higher in african americans. It can be attributed to both genetics and diet.

Well we don't taste with our teeth. Our tongue is used for tasting, it is divided into sections that taste a certain taste, For example one part of the tongue has sweet receptors on it, another part has sour receptors on it and so on. Our tongue is for tasting the food and our teeth are for grinding it up so it will digest better.

You should be flossing at least once a day.  It will catch up with you in the end if you do not.  You would be amazed how many people go well into adulthood with straight white teeth and no cavities and then end up losing all of their teeth due to bone loss caused by periodontal disease becaues they did not floss.  An old and very true saying is "only floss the teeth you want to keep"!

Americans tend to be very image-oriented.  Have to be skinny, have to have perfect hair, perfect skin, perfect teeth.  Skinny people with perfect hair, skin and teeth tend to get the better jobs, no matter how unqualified they are.  Their looks, not their abilities, are what gets them paid.\n\nI think it's stupid and that people take their appearances too far.  I agree with you; basic hygiene is good, but artificially whitening teeth is just going too far.  (When someone's teeth are too white, I assume they're wearing dentures and to me, that's very unattractive.)

The real question is why are white people white.  Most of the world’s people are “black”. The earliest humans were presumably “black”. Only people from North-Western Europe have “white” skin. White people are the mutant  form of humanity, so the real question is why.\n\n\nWhat it seems to come down to is that white people are white because there is no reason why they can’t be. There is all sorts of speculation that white skin serves to aid in vitamin syntheis and so forth, but that makes little sense since people in Tierra del Fuego, Tasmania, Siberia or Alaska do not have white skins despite living at much higher attitudes than most white Europeans.\n\n\nBasically once people left the low latitudes they no longer relied on dark pigments to protect the skin.  Those mutants born with paler skin survived and the genes gradually spread, possibly aided by sexual selection.\n\nThere doesn’t appear to be any real benefit in having white skin since people have survived perfectly well in all environments with black, brown and yellow skin.

I don't think British people practice poor hygiene as a general rule, but in the U.S. we do have the advantage of fluoride added to the water supply, which probably makes a large difference.

This is a sad observation mostly about poorer Americans (1), a distinction in the gap between the poor and the wealthy in the United States.  The poorer individuals in America have a larger tendency towards obesity, and wealth is very much correlated to obesity, as shown in this study (2).  Speaking anecdotally, you see alot of overweight individuals in urban areas and in immigrant neighborhoods, which are generally less well off than white suburban neighborhoods (3).\n\nThis is actually very odd, in less developed nations you see the reverse: the poor are starving and thin, and the rich are obese.  Often obesity is a sign of wealth and status in cultures where food is scarce (1).\n\nWhy is it that in the US, the wealthier you are, the less likely you are to be overweight?  From what I have seen, wealthier individuals have muchy better diets.  They do not eat cheap junk food like McDonalds or frozen burritos.  They also have the money to join health clubs, go to spas, and basically they can afford to lead healthier lives.

i'm assuming it's white just cause there is probably more sugar and sugar draws in moisture.
