What’s the formula for the perfect smile?

Who has the perfect smile? Emma Watson or Harry Styles? Zac Efron or Miley Cyrus?

Well wonder no longer, Scientists now say that they have come up with the formula for that ‘perfect’ Instagrammable smile! Now where’s my phone…

In summary, they say that to get that perfect smile, you have to hide your gums, you shouldn’t bleach too much, and you shouldn’t show your bottom teeth.

In addition, several researchers and scientists also commented on the current trend for the whitening of teeth, driven by the desire for a Hollywood smile.  Whilst a white, sparkling smile can open doors and make you feel confident, go too white however and your smile looks terribly fake.

For those who want something a bit more detailed, here’s the science bit (according to the researchers at the Loma Linda University School of Dentistry in the USA).  

To get a perfect smile:

  • All your visible teeth should be straight.
  • Your gums should be pink, but you shouldn’t show too much of them.
  • The width of your smile should be no less than half the width of your face at the same height.
  • The lateral teeth either side of the front two teeth, should be 61.8% the size of the top teeth. The next teeth along should be 61.8% of the lateral teeth.
  • The width of your central top teeth should be 80% of their height, and their length should be around a 16th of the height of your face. They should not be so long that they impinge on your lower lip.
  • Your upper and lower lips must be symmetrical on each side of the mid-line of your face.
  • Your back teeth should gradually reduce in size from front to back.

Is your head spinning yet??
