London: Kate Middleton`s teeth have been deliberately made "not too perfect" which helped her in giving a "natural, healthy smile, but not an artificial one", a French dentist has claimed.
Didier Fillion uses a system of "micro-rotations" and gentle whitening to make teeth look spectacular. The process involves fitting invisible braces to the back of teeth to twist them very slightly until the desired look is achieved, The Sun reported.
A state-of-the-art computer system produces a virtual 3D model of what a patient`s teeth will look like when they`re finished.
A fellow dentist Bernard Touati claimed that the Duchess Of Cambridge has used Fillion`s services.
"You know why they look good? Because they are not absolutely aligned. "He (Fillion) did some little micro-rotations on Kate Middleton to produce something which is natural. That is what we like - a natural, healthy smile, but not artificial," Touati was quoted as saying.
David Winkler, of the British Academy of Aesthetic Dentistry, said the trick was to aim for "harmonious asymmetry".
"By slightly rotating teeth, it can break up that unnatural straight line," Winkler said.
Fillion`s job takes six months to two years, and costs 4,000 to 11,000 pounds.
His other clients include actresses Kelly Brook and Sadie Frost.
