From her beautiful looks and personality, Margot Robbie checks every box to fit as the perfect human Barbie. We can’t even think of who else would fit on that role better than her, especially because if there was ever a perfect smile in this world, it would belong to Margot. Most of us can recognize a beautiful smile when we see one, but did you know there is actually some science behind the perfect smile? Stay with us to learn about the 5 reasons that make Margot Robbie’s smile, the perfect Barbie smile.

1. Smile Arc

A key factor contributing to Margot Robbie's captivating smile is the smile arc. Her teeth follow a gentle arc, mirroring the curvature of her lower lip. Can you see it?

2. Lip Line

Did you know that the average smile is considered best for this category? A low smile, just wouldn’t show enough of your teeth, while a high smile, would show too much of your gums. The “average” smile achieves the balance between both. Margot Robbie's average smile is characterized by a well-defined lip line. The upper lip follows a graceful contour, gently curving upward, revealing just the right amount of her teeth while maintaining a natural appearance.

3. Teeth size

In case you haven’t figured it out by now, teeth are not supposed to be the same size. The optimal length of teeth in relation to one another, going from the center to the sides (central incisor to the first premolar), follows a gradual decrease in size.

• Central Incisor – The focal point of the smile: The central incisors are the two front teeth in the upper jaw and are typically the longest and most prominent.

• Lateral Incisor – The complement of centrals: The lateral incisors are located next to the central incisors and are slightly smaller in size.

• Canine – The character of the smile: The canines, also known as cuspids, are the next teeth along the dental arch. They are larger and more pointed than the lateral incisors.

• First Premolar - Transitional teeth: The first premolars, also called first bicuspids, come after the canines. They are smaller than the canines but larger than the incisors.

4. Teeth shape

Most people think teeth are supposed to be perfectly square, but that may only fly in Barbie’s plastic world. The optimal shape of the four frontal teeth, going from the central incisor to the first premolar, should exhibit a gradual transition in form while maintaining harmonious proportions:
