Types of tooth shapes

Our teeth, like many parts of our body, can have different shapes, sizes, and structures depending on factors such as age, gender, and race. In some people, the same teeth may be thicker or thinner, larger or smaller, sharper or straighter. The features you see in your teeth may be the result of thousands of years of mutations from your ancestors. There is a variety of teeth in our mouth.

All our teeth are not the same, each of our teeth has different characteristics that differ according to their function. Each of them performs an important function during eating, due to the cooperation of all teeth together, healthy mechanical digestion is carried out. In this article, we will review some of the different types of tooth shapes and their functions, then we will look at the teeth shape guide and talk about the appearance of some genetic inheritance in the teeth.

What are the four types of tooth shapes?

There are four types of teeth. All teeth have their functions that are directly related to their shape. While eating, using mechanical movements, we pierce, tear, cut, and chew food, this process is called mechanical digestion.

We divide teeth into four groups based on their shape, each of which performs a different function. The sharp teeth perform the cutting action while the broad, flat teeth perform the chewing action. They are arranged according to their functions from front to back. The front teeth are responsible for cutting and tearing food, and the back teeth are responsible for chewing. Middle teeth also have their characteristics related to their tasks.

incisors:

Incisors are our front teeth. There are a total of eight teeth for cutting. Four teeth in the lower jaw and four teeth in the upper jaw.

They have a thin and broad structure that tapers towards the tip. They are like knives when they hit something, these teeth pierce it and go inside. These teeth are usually the first teeth to appear in babies. Baby teeth appear at the age of six months and permanent teeth appear at the age of 6-8 years.

Fangs:

The fangs are the sharpest teeth you have. They are located in the lower jaw and two of them in the upper jaw and surround the incisors.

They are used to tear up food because they have a sharp tip. When we eat, the canines dig in hard and stop them from coming out of our mouths. So, they also help our front incisors to tear up pieces of food. they do.

Canine teeth grow in babies at the age of 16-20 months, and large canines appear at the age of 9-12 years.

Small molars

Premolars are like a transitional stage between canines and molars. They have some characteristics of both groups of teeth. These teeth are active in chewing, tearing, and cutting activities. They are rectangular like large molars, but do not have two or three ends.

We have a total of eight small molars, four in the lower jaw and four in the upper jaw. Baby teeth do not have small molars. Baby molars appear in adults between the ages of 9 and 13.

Big molars

They are the largest number of teeth in our mouth. These teeth are known as our widest teeth. They have a rectangular structure and a smooth surface. They have four or five ends.

Their main tasks are chewing and crushing. There are 12 of them, 6 in the lower jaw and 6 in the upper jaw. Baby teeth appear between 12 and 16 months. Complex adult teeth appear between the ages of 10 and 12.

The shape of the teeth corresponds to their form

The shape of teeth can change based on various factors. As the shape of the teeth is formed based on genetic factors, according to your use, the shape of the tooth may also change over the years.

We can divide the shape of natural teeth into three categories. These include rectangular teeth, triangular teeth, and elliptical teeth.

These types of teeth, if they are flawless, are permanent in people from birth to adulthood. However, as we said, it is normal for the shape of the teeth that we use mechanically for years to change.

Teeth gradually deteriorate with age, so some types of teeth are associated with youth. For example, a person with teeth grinding problem (bruxism) constantly grinds his upper teeth against the lower teeth, this causes erosion of the tooth surfaces in the long term.

You can see that the oval-shaped teeth become smooth after a while, the shape of the teeth has a good function in addition to the aesthetic value. Some people may find a certain shape of teeth more beautiful.

Although the perception of beauty varies from person to person and culture to culture, you may want to change the shape of your teeth to feel more comfortable with your appearance. If you ask dentists about this, they can only guide you about treatment options.

Triangular teeth shape

Triangular teeth are wide at the tip and narrow towards the root. When referring to the triangular shape of the teeth, you can see the triangular spaces between the teeth and the gums. Also known as black triangles, these spaces are perfectly normal as long as they fit the shape of your teeth, and even help you clean between your teeth more easily. However, they should be related to the shape of your teeth. The appearance of black triangles that were not there before may be a sign of gum recession.

Square teeth shape:

Strings that are square are very easy to identify. They do not show up or down contractions. The end borders look like a straight line. Different teeth that wear down over time can also be approached this way.

The shape of oval teeth:

The shape of the oval teeth is more prominent in the central part of the tooth, which narrows towards the root and tip. Its tip is not straight, but has a curved structure.

Dental tooth shape guide

When we talk about dental prostheses, the factor that plays an important role besides health is the aesthetic aspect of the work. The main function of some prostheses, such as veneers, is to show beauty. When it comes to dentures, the aesthetic aspect is not the most important part. Of course, people are looking for various options where they can find what is beautiful and suitable for them. Therefore, there are various options for artificial teeth, we can describe the main ones as follows.

Some of them may have a different aesthetic meaning in some societies. For example, the type of aggressive teeth is suitable for people who want to have a strong and determined personality. Advanced teeth types are preferred by models, you can even find websites on the internet that do personality analysis on the shape of your teeth. This can be fun as long as you don’t take it too seriously.

Shape of teeth according to race

The genetic group is a determining factor in the type of shape of your teeth. Like gender and other factors of genetic inheritance, people who live in different regions of the world in different conditions and come from different generations are very diverse in terms of the shape of their teeth. You might even be able to guess your ancestry from it. The history of medicine in classification based on race is also associated with many hidden problems. However, today we can talk about these classifications in a non-racial medical context. Some genetic groups may have sharper, larger, or smaller teeth and the tooth enamel may be thicker or thinner, in fact, people living in certain regions of the world may have more or fewer wisdom teeth. In the following, we will examine some of the tooth shapes associated with this breed.

Asian teeth shape

The main feature of the Asian tooth is its prominent shape. This prominent tooth can be defined as the middle of the teeth which is empty and the ends are relatively thick. This feature is especially seen in people who are Asian, red-skinned, and Native American.

In Europe, this feature is also found in collections belonging to Hungarians or other communities of Asian origin. However, it is not often seen in people of European and African descent.

The shape of the teeth of Native Americans

As mentioned above, spade-like incisors are common in Native American countries. In addition, some other traits are very common in Native American communities, although very rare in the rest of the world.

One of them is rope cusps. Also known as “Eagle Claw Cusp”. In this case, the front view of the teeth is normal, but behind the incisors, some ridges may be conical.

This is also a rare mutation worldwide, but it can be found more often in certain native countries of North America. In addition, winged incisors are also common among Native American peoples. This is a condition in which the two anterior incisors are at a different angle than the alignment of the other teeth.

What is the shape of ideal teeth?

When it comes to an impressive smile, the first thing that comes to mind is teeth. You cannot have a perfect smile without perfect teeth. However, the ideal teeth shape, perfect smile, and Hollywood smile are worthy of debate.

Being beautiful is something that can vary greatly from culture to culture and even from person to person. In addition, the beauty of your teeth cannot be separated from your face. Everyone has unique faces with unique proportions and proportions that complement each other. So actually, “Which one is more beautiful for me?” It is more reasonable to ask what we mean by this: some types of teeth are more suitable for some people and not for others.

The shape of your face, its dimensions, and the structure and size of your mouth and nose, all form a whole with the type of shape and alignment of your teeth. If you want to look good, it helps to consider your teeth as part of this. For example, the shape of square or rectangular teeth is more attractive to many people and these shapes are preferred. However, this may not be suitable for everyone. An exaggerated rectangular shape can resemble a horse’s teeth. More curved edges may be more appropriate. So it is better to decide on this matter after consulting with cosmetic dentists in Toronto and thinking deeply from this point of view.
