Hollywood Smile with Dental Experts
If a smile is a painting, then the lips are the beautiful frame of that painting. The captivating highlight in that frame is the bright, white teeth and even gums. In this article, The East Rose Dental Clinic would like to share the standard criteria for a perfect smile, which you can easily change and enhance thanks to modern dental techniques.
Important criteria for evaluating a perfect smile
A perfect smile not only brightens your face but also boosts your confidence in daily communication. However, to achieve that smile, you need to meet some important criteria. Below are the 4 most essential criteria; you can read this article and see how many of these you meet.
1. Perfect ratio between teeth and gums when smiling
To achieve a perfect smile, your teeth need to have the right width and length, with elongated shapes, sharp and refined edges. The teeth must be closely aligned with each other, along with the gums and facial contours, creating harmony and balance.

The ratio between the height and width of the teeth should range from 70% to 85%, depending on the face shape and mouth structure. Specifically, the ideal ratio between the width and length of the two upper front teeth is 77%, while the front side teeth, molars, and canines have a ratio ranging from 62% to 80%, depending on mouth size.
The tilt of the teeth is also crucial; all teeth need to grow in the correct direction, with a slight tilt and tight contact points from top to bottom. The contact points between the teeth gradually move closer to the gums as they reach the inner teeth. The color of the teeth should also be bright, uniform, and naturally translucent, giving a refined and elegant look. A perfect tooth color will help you feel more confident in communication, make a strong impression, and easily open up many opportunities for success in life.
2. The correlation between eyes, mouth, and the facial symmetry axis

One of the equally important factors in designing a perfect smile is the balance between the eyes, mouth, and the symmetry axis of the face. The ratio between the two sides of the teeth must create a central line, passing through the gap between the two front teeth, forming a perfect symmetry axis. This line not only lies in the middle of the dental arch but also must pass through the philtrum and the center of the face, helping to create perfect symmetry for the entire face.
The shape of the dental arch also plays a key role, as all the teeth need to be evenly arranged to form a perfect arch when smiling. This harmonious alignment will enhance the appearance of the face, giving a confident and attractive smile, especially when you communicate or take photos, just like Hollywood stars.
3. Gum line – the key factor in the beauty of a smile
The gum line plays an important role in creating a charming and natural smile. It is the intersection between the contact points of the gum line and the teeth in the upper jaw. A standard and graceful smile will have the gum line just below the upper lip line, while revealing the upper front teeth as much as possible without exposing too much gum tissue.

The symmetry of the gums is also very important. The gums must be symmetrical along the center line of the face, with the gum edges following this principle. When smiling, no more than 3mm of gum tissue should be visible, helping to create a natural and harmonious smile. Specifically, the distance from the outer surface of the premolar to the corner of the lip should be minimal, enhancing the beauty of the smile.
Additionally, the gum contour needs to be adjusted. When drawing a line from the gum peak of the canine to the gum peak of the two front teeth, the gums of the side teeth should be 1 to 2mm lower than this line, creating harmony and precision for every detail on the face.
4. The smile line – the golden criterion for a perfect smile
An ideal smile line is not only graceful but also reflects the balance and harmony of the face. The most important criterion is that the corners of the mouth must be parallel to the eyes. This forms the foundation for creating a natural smile that harmonizes with the facial proportions.

The smile line is the connecting point of the upper dental arch, and an ideal smile line follows an arc shape, approaching the lower lip contour, creating softness and balance for the mouth. A curved smile line will make you appear younger and full of vitality, adding to the attractiveness of your smile. Specifically, women often prefer a curved smile line over men, as it not only provides a youthful look but also expresses femininity and charm.
We hope that the above article has given you an insight into a perfect Hollywood smile according to dental criteria.
