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. Men tend to show less of their upper teeth (hence the expression “stiff upper lip”).
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.
The ideal smile involves strict mathematical ratios, the research states. Its width should be no less than the half of the face's width. Both lower and upper lips should be symmetrical on each side of the facial mid-line. The smile should reveal most of the upper teeth and very little or none of the lower teeth.
The rarest smile type is the complex smile, with only an estimated 2% of the population possessing this smile. This smile is rare because it requires three muscle groups to work simultaneously when smiling.
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.
Smiling with your eyes—or “smizing”—is a hallmark of a genuine smile. Try covering your mouth so that only your eyes and eyebrows are visible in the mirror. You should be able to “see” the smile even without seeing your mouth.
The influence of teeth on the aesthetic appearance of a person has been known for a long time. Based on a large number of empirical results, it can be assumed that white, straight teeth are considered a beauty ideal in Western culture.
Harry Styles may have six BRIT awards and two Grammys under his belt – but his mouth has seen him win big. The cheeky Cheshire chap has come out on top and been crowned the owner of the world's most attractive smile according to leading dentists.
There are several factors that can contribute to the front teeth not being visible when we talk or smile. These include the way we pronounce syllables, the position of our teeth, and the position of our lips. Teeth can also be less visible because of the shape and size of the jaw.
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.
“The only place that will reveal the difference in a broad intense smile is the skin between the eyebrows and the upper eyelid. That will move slightly down in the genuine smile and will not move in the social or false smile.
A good rule of thumb when determining how white your teeth should be is to look at the whites of your eyes. Whether whitening at home or undergoing treatment by a professional dentist, you should be aiming for a shade of white similar to that of your eyes.
People who smile less broadly risk appearing 'contemptuous' if they show their teeth, US researchers found. Instead, if your grin is smaller and less effusive, a tight-lipped smile may make you look more genuine and friendly.
The pointed ends of the top teeth should fit perfectly between two teeth in the bottom. The backs of the upper front teeth should rest in gentle contact with the fronts of the lower ones. Essentially, your bite should “close”. If your front upper teeth stick out past your lower teeth, this is called an overbite.
The truth is that most people show at least 8 upper teeth when they smile and at least 6 lower teeth when they talk! To see what we mean, take a look at Dr. Harper's “Before and After” gallery.
Open Bite. In an open bite, your upper and lower teeth are vertically aligned. When you close your smile, though, your front upper and lower teeth don't touch. This type of malocclusion appears to happen in people who suck their thumbs longer than recommended as a child.
Some of the most common causes are: An uneven gums: There are cases where one side of your gum line can drop down lower than the other side, giving the impression of asymmetry. Misaligned teeth: If your teeth are crooked, tipped, or rotated, your smile can appear jagged and uneven.

When people feel uncomfortable, such as when someone says something inappropriate, they may engage in an uncomfortable smile designed to cover up their true feeling of discomfort.
