This reminds me of when I was kid that a neighbor whom same age with my grandmother, her teeth use layer yellow across the surface of all the teeth. We call it a gold tooth. So when he smile, her teeth become visible flashing. But do not imagine that this tooth is actually made of gold like that used by the rapper and celebrity world. According to a story in my grandmother's era, people wore gold teeth has been around since antiquity. This is a symbol of "prosperity" economically for its owner. So people who want to follow the trend at that time wore yellow teeth but it was not made of gold. Only imitation. Just for style. I myself did not know until now what the material used to make this teeth.
Beuh ... think about it makes no difference to this time ... for the rich, wearing colorful braces that worth up to tens of millions also is a symbol of economic well-established for the owner. Trends are now wearing braces like this is believed to make the wearer look more attractive. Whether for that reason jugakah? So commonly seen many rich people who actually have teeth without problem but felt it necessary to wear braces. I do not know ....
Compare the two pictures below, whichever seems more interesting in your opinion:

Perhaps at times my grandmother's, first picture is the best style because they do not recognize the style as shown in Figure 2. But if today there is a young man wearing teeth like picture 2 maybe be like a joke. Opinions differ, if in place at different times, isn't?
