Symmetry and Proportionality

Golden Proportion A smile is considered to be esthetically pleasing if each tooth in that smile is 60% of the size of tooth immediately adjacent to it. The exact proportion of the smaller tooth to large

A Central incisor is considered perfectly proportionate when the maximum width is approximately 75% of the maximum length of the clinical crown.

The central incisor reflects patient’s personality. Lateral incisors provide the charm and canines the strength.

The shape of central incisor whether square, ovoid or rectangular is often related face upside down.

The height of an ideal maxillary central incisor from the incisal edge to the gingival crest is 1/16th of the distance from inferior border of chin to interpupillary line.


Width of maxillary central incisor is measured from mesial to distal contact areas and is 1/16th of the distance measured from either zygomatic prominence through an imaginary facial midline.

The distance between the posterior border of incisive papilla to the outer labial surface of the central incisor is 12.5mm.

The end of first palatal ruga is located 1.5 mm to 2 mm from the lingual surface of canine.

Young teeth characteristically exhibit significant surface characterization whereas teeth in older individuals tend to possess a smoother surface texture caused by abrasional wear.


Teeth are typically composed of multitude of colors. The gingival third is darker than incisal third because of thinner enamel.

In most individuals canines are slightly darker in color than incisors.

Exposed root surfaces are darker because of absence of overlying enamel.

Young people with thick enamel have lighter teeth.

As a person gets older, the facial enamel is worn away. The underlying dentin becomes more apparent, resulting in a darker tooth.

People with dark complexions usually appear to have lighter teeth because of the contrast between teeth and surrounding facial structures.

Females can enhance the apparent lightness of their teeth by using a darker shade of makeup or lipstick
