Have you ever wondered the dental formula of human, What it is and Why it Matters, how many teeth you have and what they are called? If so, you are not alone. Many people are curious about their dental anatomy and how it affects their oral health. In this blog post, we will explain what the dental formula of a human is, how it differs from other animals, and why it matters for your dental care.

What is the Dental Formula of Humans?

The dental formula of humans is a way of describing the number and types of teeth that humans have in each quadrant of their mouth. A quadrant is one of the four sections of the mouth, divided by the midline of the upper and lower jaws. The dental formula of human is written as follows:

This means that in each quadrant, humans have two incisors, one canine, two premolars, and three molars. Incisors are the front teeth that are used for biting and cutting food. Canines are the pointed teeth that are used for tearing food. Premolars are the teeth that are located between the canines and the molars, and are used for grinding and crushing food. Molars are the largest and strongest teeth that are used for chewing and mashing food.
The dental formula of humans can also be written as 2I, 1C, 2P, 3M, where I stands for incisor, C stands for canine, P stands for premolar, and M stands for molar. This is a shorthand way of expressing the same information as the fraction notation.

How Does the Dental Formula of Humans Differ from Other Animals?

Humans are not the only animals that have teeth. In fact, most mammals have teeth, but they vary in number, shape, and function depending on their diet and lifestyle. For example, herbivores (animals that eat plants) tend to have more molars and fewer canines than carnivores (animals that eat meat), because they need to grind and digest plant matter. Carnivores, on the other hand, tend to have more canines and fewer molars than herbivores, because they need to tear and rip flesh. Omnivores (animals that eat both plants and animals) tend to have a balanced dental formula that allows them to eat a variety of foods.
Some examples of the dental formula of different animals are:

As you can see, the dental formula of humans is different from other animals in several ways. One of the most notable differences is that humans have fewer teeth than most other mammals. Humans have 32 teeth in total, while dogs have 42, cats have 30, horses have 40, cows have 32, and elephants have 26. Another difference is that humans have the same number of teeth in each quadrant, while some animals have different numbers of teeth in the upper and lower jaws. For example, dogs have one more molar in the lower jaw than in the upper jaw, while cows have no incisors or canines in the upper jaw at all.

Why Does the Dental Formula of Human Matter?

The dental formula of human matters because it reflects the evolutionary history and dietary habits of our species. Humans are omnivorous, meaning that we can eat both plants and animals, and our dental formula reflects that. We have incisors and canines that allow us to bite and tear food, and premolars and molars that allow us to grind and chew food. Our dental formula also shows that we are primates, meaning that we belong to the same group of mammals as monkeys and apes. Primates have a similar dental formula to humans, with two incisors, one canine, two premolars, and three molars in each quadrant.


The dental formula of human matters because it affects our oral health and hygiene. Knowing the number and types of teeth that we have can help us take better care of them and prevent dental problems. For example, we can brush and floss our teeth regularly to remove plaque and bacteria that can cause tooth decay and gum disease. We can also visit a dentist regularly to check for any signs of dental issues and get professional cleaning and treatment. We can also avoid eating foods that are too hard, sticky, or sugary that can damage our teeth and enamel.
