London: Scientists have undertaken a new study to find the reason why some smiles are like grimaces, and why some, like Cheryl Cole’s, are so brilliant that they can turn people into stars.
The 28-year-old singer’s smile is said to fit into the “formula” for a perfect smile, which comprises of a mix of colour, tooth shape and, most importantly, sincerity.
David Holmes from the Manchester Metropolitan University found that different muscles are used, particularly around the eyes, in sincere smiles, and these help to create a smile people find attractive.
His team devised a formula for the “perfect” smile, combining confidence, face shape, lip and tooth health, for a dazzling effect that can win people over and even help with career success.
“Cheryl Cole is a great example of the perfect smile. It’s no coincidence that she has been such a success and become the nation’s sweetheart,” the Daily Mail quoted him as saying.
“Her smile helps her come over as genuine, attractive, and engaging,” he said.
According to Holmes, if the teeth and lips are in good condition, with a fleshy “cupid’s bow”, people respond even more strongly.
“A major factor is how well you can produce a full ‘arch-bow’ smile.
“A wide, deep crescent revealing teeth but not gums, and reaching up to the eyes,” he said.
The researchers said that Cole’s perfect “arch bow” smile, a wide, deep crescent revealing teeth but not gums, has helped propel her to her status as the nation’s sweetheart.
