LONDON: A perfect smile 😃 depends not only upon the whiteness of a person's teeth but a number of other factors also, say scientists.Dr Nicholas Davis of Loma Linda University School of Dentistry in Southern California says that right size and width of each tooth, right curve, colour and shape of the teeth, and the overall width of the mouth are the factors which together contribute to a lovable smile😃. He feels that the whiteness of the teeth should match the whites of the eyes, else the smile will stand out too much 😃 and detract from the rest of the face😳. "One of the first things about a smile 😃 people notice is the colour," the 'Daily Mail' quoted Dr Davis, as saying.
"People are bleaching their teeth and many times they do it beyond what is natural.
The teeth should be the same colour as the whites of your eyes. If the teeth are too white, they become more dominant than the eyes😳," he added. Describing his formula for a perfect smile 😃 in the journal 'Dental Clinics of North America', Davis said that the ideal width of a smile 😃 should not be less than half the width of the face, and both upper and lower lips should be symmetrical each side of the mid-line of the face. He says that the top row of teeth should be dominant, while very little should be seen of the bottom row.
Davis also says that all the teeth on display should be straight, and there should not appear any signs of restoration work. Exactly how long the central teeth should be varies, but they are too long if they interfere or impinge on the lower lip. The back teeth should diminish in size from front to back.
While the width of the central teeth should be 80% of their height, the laterals should be 61.8% the size of the bigger teeth.
Gums are important, and to avoid a horsey smile😛, very little should be seen😳. Their colour is critical, and should be a healthy pale pink.
Dr Oliver Harman, a London-based dentist whose clients include Catherine Zeta-Jones, recommends regular 'mouth manicures' to remove stains. He says that it is not necessary to rectify all imperfections with expensive cosmetic dentistry.
The British Academy of Cosmetic Dentistry asked respondents for a latest survey how they felt about their smiles 😃. Apparently, 32% said they were 'concerned by the look of their teeth'😳, while nearly 20% 'usually conceal their teeth in photos'😳. A mere 25% said they were completely happy 😃 with the way their smile looked.
Davis said Jessica Simpson, who starred in the 2005 film The Dukes Of Hazzard, had most people's idea of the perfect smile. "Jessica is the one we get asked to reproduce the most," he said.
According to the BACD survey, Kylie Minogue pipped Julia Roberts for the best smile, while George Clooney cleaned up in the men's section. Last week, Ewan McGregor and Julia Roberts were crowned monarchs of the grin, by International Stress Management Association.
