Horizontal Line Conformity: The pupils, corners of the lips and the teeth’s cutting edges should line up in parallel to each other.
Smile Line: The curve formed by the cutting edges of the teeth should be symmetrical to the lower lip’s curve. The degree of symmetry influences how youthful and attractive a smile is.
Gender and Tooth Shape:
Women: The corners of the teeth are rounder while the smile line curves straight up.
Men: The teeth are pointier while the smile line is straighter.
Smile Symmetry: The mid line of the teeth should be straight and in line with the middle of the lips and the point of the nose.
Teeth Arrangement: The teeth’s positioning is an important aspect of having a beautiful smile.
Spacing: Gaps between the teeth poorly affect smiles.
Colour: Pearl white teeth mean a younger and healthier smile.
Size: Shorter teeth make people look older. Enlarging especially the front 2 incisors will make smiles look livelier and patients younger.
Gum Health and Visibility: Prominent gums can negatively affect a smile’s aesthetics.
Shape and Thickness of the Lips: These are important factors for an impressive smile and need to be taken into consideration when your new smile is being designed.
Nose Shape: This too affects your smile and also needs to be taken into consideration when your new smile is being designed.
The Golden Ratio: The golden ratio is the mathematical expression of the teeth in relation to each other and other surrounding factors mentioned above. Assuming the width of the front 2 incisors is 100, the teeth immediately next to them should have a width of 60, while the visible surface area of the subsequent 2 teeth should be 60% of those. Achieving this proportionality indicates an aesthetic smile has been achieved.
