Creating the Scientifically ‘Perfect’ Smile – Fresh Dental

July 6, 2017

Everyone wants the perfect smile, and it takes more than just the mouth to achieve it.Hide the bottom teeth, cover the gums and set the lips at the right angle. These three work together to create the perfect smile, according to a scientific formula derived from a group of researchers. The research team took into account everything from the size, colour and width of each tooth to the overall shape of the face.Previous studies have shown that improving the smile’s appearance can contribute to a range of physical and emotional benefits, including more positive attitudes and higher self-esteem. So, creating the ‘perfect smile’ can have more than just a short-term, skin-deep effect; it can have a life-changing impact.According to the study, the following features and factors comprise the Perfect Smile:

Face, Gums, Teeth and Lips

Creating the perfect smile considers all kinds of factors and dimensions. These include the size and shape of the face, the lips, gums and teeth. Colour and shape are also important.

Ratio and Proportion

The ideal smile involves strict mathematical ratios, the research states. Its width should be no less than the half of the face’s width. Both lower and upper lips should be symmetrical on each side of the facial mid-line.The smile should reveal most of the upper teeth and very little or none of the lower teeth. The teeth on either side of the front teeth (laterals) must be 61.8% the size of the bigger teeth. The length of the central teeth must be about 1/16 of the facial height, and the width must be 80% of the height. The ideal height of the central teeth varies, as long as they do not interfere with the lower lip.


Crooked teeth have no place in the ‘Perfect Smile’. All of the visible teeth must be even and straight, and all restoration works you have had in the past must not be apparent. Avoid what some may describe as a ‘horsey’ smile, by hiding most of the gums, and if visible, they must be pink.


One of the most noticeable things about a smile is the colour of the teeth. They must be the same colour as the white of your eyes. Leaving the bleach on too long creates an unnatural effect that is more unpleasant than appealing.
