This discussion is really somewhat of a social commentary on modern standards for beauty. On the one side are those who thought she looked adorable before but now react in shock to uneven teeth. On the other are those who criticised her as a fake-cute attention whore, but now feel sorry for her because she isn't perfect.
Hollywood and Madison Avenue have a long history of pumping images of superhuman beauty upon the masses, a beauty which is unobtainable to the majority who lack the financial means to procure it. And yet, society continues to hungrily consume images of this shallow and artificial perfection with its breast augmentation, hair coloration and extentions, dental veneers, botox, liposuction, and all manner of cosmetic surgery. Not that this is anything new. For ages make up, wigs and expensive clothing have separated the haves from the have nots, but now we go beyond the wrappings and into modifying the human body itself. And lest ye think this is just about the ladies, men are increasingly consuming hair coloring, dental and surgical services in the frantic quest to look like the ideal man.
Quite frankly, I can't tell the modern starlets apart half the time. They have the unimaginative, uniform appearance of mass produced automobiles coming off an assembly line. Given my druthers, I'd rather look upon the imperfections and blemishes that accompany natural beauty than gaze on these inanimate golems that vanity and modern medical science have unleashed upon us. I knew a girl back in college who appeared to be quite pretty, but up close I could see that she caked on an extremely thick layer of foundation make up. It was so heavy that I could have stuck a finger in each of her nostrils and a thumb in her mouth and carried her around like a bowling ball. I couldn't help thinking "Girls are made of sugar and spice and artificial coloring". It was a big turn off.
Anyhow, off the soapbox and back to the discussion. If we were to hypothetically ignore the controlled environment portrayed in the YouTube videos, we'd see a young lady with pretty eyes and hair, a nice figure, and a crooked incisor. The whole being the sum of its parts, she'd still be considered attractive. Whether that's good enough in the 21st century where money and a deftly handled scalpel can alter the human form as easily as a tailor can custom fit a suit of clothes is a question I'll leave to the philosophers.
