FOY Dentures®, The Denture Fountain of Youth®, are designed to give you an attractive smile. There’s no reason why someone with dentures shouldn’t be able to have as attractive a smile as someone with natural teeth. In fact, you might be able to get an even better smile with dentures than with your natural teeth, because dentures let you completely start over with a fresh slate.
There are many aspects of designing an attractive smile for FOY Dentures®, but one we like to use is the Golden Ratio, also called the Golden Proportion, a proportion commonly seen in nature that is inherently pleasing to the eye.
You’ll have to forgive us for math-nerding-out here, and we think it’s only fair to warn you there will be some math in this section. If you don’t want to learn the math or you already know it, you can skip down to see the take-home message.
In the Golden Ratio, the proportion between two numbers is the same as the proportion between the higher number and the sum of the numbers. Yeah, I know, anyway, here’s what that looks like in an equation: (a+b):a=a:b. If you define a as 1, then b is approximately 0.618.
One cool thing about the Golden Ratio is that it’s also defined by the Fibonacci sequence. In a Fibonacci sequence you start with 1 and 0 and generate each new term of the sequence by adding up the two previous numbers, like this: 0,1,1,2,3,5,8,13 and so on. When you compare the numbers, you can see how they get closer and closer to the Golden Ratio: 3:2=1.5, 5:3=1.67, 8:5=1.6. It’s not very long before it gets very close indeed: 55:34=1.618.
The Golden Ratio wouldn’t get that much attention except for the fact that we keep coming across it in nature. For example, if you look at the spirals of seeds in a pine cone, you have 8 spirals going one way and 13 the other way. Flower petals usually have a Fibonacci number for their petals. The spiral of a snail shell conforms to the Fibonacci ratios. For more cool examples, check out this video by mathemusician (yeah, that’s a thing) Vi Hart or read this article.
The Golden Ratio is even found in your smile.
There are two main places where we suspect the Golden Ratio plays an important role in making an attractive smile. The first is in the ratio of your tooth height to its width. This is a little hard to verify in natural smiles because wear changes this proportion, making it harder to verify.
But one place we do know the Golden Ratio impacts the attractiveness in your smile is in the relative width of your teeth. The central incisor should be 1.618 times the width of the lateral incisor, which is 1.618 times the visible width of the canine. This proportion is found more in attractive smiles than in unattractive smiles–and it can make an attractive smile for your dentures.
