Ideally, your smile should reveal most of your teeth and form a gentle arc, sweeping back into the “buccal corridor,” the dark space between your teeth and the corners of your mouth. A little dark space is important to create contrast and make your teeth seem whiter.
To be considered conventionally attractive, your smile should have the same midline (vertical line that splits the face perfectly in half) as your face. If your smile's midline isn't directly between your two central front teeth, it might look unattractive.
Attractive smiles have various things in common, such as teeth that are white, unstained, straight, evenly spaced with no gaps between them and not crowded or overlapping. When you smile, your top teeth show fully in a good proportion to your gums. The line where the gums and teeth meet is smooth and even.
The Duchenne smile. This one is the gold standard. The Duchenne smile is also known as the smile of genuine enjoyment. It's the one that involves the mouth, the cheeks, and the eyes simultaneously.
In an ideal smile, 100 percent of your central and lateral upper incisors and your canines should be visible, Hilton says. Usually your upper premolars and part of your first molar should be on display.
If you want your smile to appear pleasant, you might want to avoid a dazzling beam, research suggests. A study by scientists in the US has found that wide smiles with a high angle and showing a lot of teeth are not the best at creating a positive impression.
It's usually a balance between mouth angle (from center of the lip to corner of top lip and bottom lip), extent of the smile (length of smile from center of lower lip to corner of right lip), and how much teeth are showing (between the upper and lower lip).
A flirtatious smile, sometimes called a Mona Lisa smile, is characterized by eye contact, a slight smile, and a slight head tilt.
The Charismatic Complex Smile
A complex smile lives up to its name. It's the most complex smile style, and it's also the most rare, found in only about 2% of people naturally. A complex smile combines the movements in both the other smile styles and adds to it a simultaneous lowering of the lower lip.
Dental professionals consider a square-shaped jaw one of the most attractive because it shows that someone has a strong jawline and thin lips. On the other side of that spectrum is a round-shaped jaw with protruding teeth that can make a person look like they have an overbite or underbite.
Youthful Proportion
Youthful smiles tend to have a very marked difference in the size and shape of the central incisors when compared to the other teeth. Not only are these teeth wider than the other teeth, but they also tend to be taller.
Science says a cheerful facial expression may compensate for relative unattractiveness. In two experiments, researchers in Switzerland examined the relationship between attractiveness and smiling. They found that the stronger the smile, the more attractive a face looked.
Unattractive smile is a feature that can adversely affect the self-image of an individual. An unattractive smile can be present because of a number of factors that include dark teeth, missing or broken teeth, receding gums, and protruding teeth or jaw.
Facial beauty is heavily reliant on having eye-catching features. In particular, the nose should be straight and balanced, the eyes should stand out, the lips and smile should draw you in, and the cheekbones should round out your face nicely.
Studies show that those with white and well-spaced teeth appear more attractive. Some people think it's superficial, but it's not. Having beautiful teeth is linked to good oral hygiene. As a result, they appear to be more intelligent, and more successful, and yes, they have more dates.

It turns out that there's a magic number of upper teeth to have on show for an appealing and youthful smile and that's at least eight, says dentist Dr Rhona Eskander, who is increasingly helping her clients achieve that coveted wider smile.
Your lower teeth should hardly be visible and the aim is to show your top teeth. Your two central upper teeth should be the focus of your smile, but you should not push them over your bottom lip – this will make them too prominent. The lipline should not show more than 2 mm of gum.

You may not have realized this, but teeth are not meant to touch. It sounds odd, but think about it. They don't touch while you speak, smile or rest. Even when you chew, your teeth only have to be close enough to mash food, not necessarily touch.
