How many teeth do humans have?

Teeth are extremely important, but they are frequently overlooked. They assist us in biting, chewing, and swallowing food. They also assist us in communicating. The teeth are one aspect of the body that is frequently neglected.

The number of teeth a person possesses may vary from person to person or depend on a variety of factors. It’s possible that not all of your adult teeth will come in, or that some of your teeth will be damaged. Adults, on the other hand, have nearly the same number of teeth.

Even though there is an estimated number of teeth that humans should have in their lifetime, this is not always the case. This post will teach you about teeth in general, how many teeth a human has, and other interesting facts you may not be aware of.

What is the structure of the teeth?

The enamel, dentin, and pulp are the three layers that make up each tooth. The enamel is the white covering that we all see on the outside. It is a hard surface that protects each tooth’s inner layers against decay. Enamel is the toughest tissue in the human body.

The dentin, which is related to bone tissue, is the central layer of the tooth. It is responsible for the majority of the tooth’s structure. The dentin and pulp are connected by millions of small tubes (also known as the life source of the tooth)

The pulp is the source of a tooth’s life. Alternatively, it is the tooth’s innermost later, which contains blood and nerves.

The crown (the part of the tooth above the gum line) and the root (below the gum line) are two other sections of the tooth. It’s also in charge of securing the tooth to the jawbone).

The types of teeth

The incisors, canines, premolars, and molars are the four types of teeth.

They are four in number when it comes to incisors. The four front teeth on the top and bottom jaws are known as incisors. Incisors are knives that are used to cut and chop food. They chop food into smaller pieces, which are subsequently moved to the rear of the mouth by the teeth and tongue.

The sharp pointy teeth in your mouth are known as canines. ‘Fang teeth’ is a term used to describe them. There are two on each side of your incisors on the top and bottom jaws, for a total of four. They’re for chopping and shredding food. They also keep the upper and lower rows of teeth from colliding.

The canine teeth are placed adjacent to the premolars. Bicuspid teeth are another name for them. Most adults have a total of eight premolars.

There are four along the top gums and four along the bottom gums, with two on each side. They’re significantly larger and wider than your incisors and canines. Food is crushed and ground in the premolars.

Molars are the most powerful teeth. They help you swallow food by working with your tongue. They accomplish this by crushing the food until it is safe to ingest. There are 12 molars in all, six on top and six on the bottom. There are also four wisdom teeth.

How many teeth do humans have?

When people reach adulthood, how many teeth do they have? A total of 52 teeth are expected to spring up in the life of a human (from when a baby is born). Only 20 of these are milk teeth, with the remaining 32 being adult teeth.

At any point in time in the life of humans, they are expected to have a maximum of 32 teeth, hence people can have lesser numbers depending on several factors.

By the time you reach the age of 21, you should have all of your adult teeth firmly embedded in your gums. This isn’t always the case, though.

Persons between the ages of 20 and 64 have an average of 24.92 remaining teeth, according to the National Institute of Dental and Craniofacial research, while 3.75 percent of adults in this age range have no remaining teeth.

According to a survey by the Surgeon General most Americans have lost an average of 12.1 teeth by the age of 50. According to the Centers for Disease Control and Prevention (CDC), 26% of older persons over 65 have eight or fewer teeth, and 17% have lost all of their teeth.

What is the average number of teeth in an adult?

A full set of teeth, 32 in number, is typical of an adult. When you reach your late teens, your adult teeth begin to emerge. Adult teeth include eight incisors, four canines, eight premolars, and twelve molars.

What is the average number of teeth in a baby?

Around the age of six months, babies begin to obtain their new teeth. Teething can appear in a youngster as young as three months old. Primary teeth are also known as deciduous teeth.

They’re termed primary teeth because they’re only there for a short time and will eventually fall out. A complete set of newborn teeth consists of twenty teeth: ten on top and ten on the bottom.

How to Take Care of Your Child’s Teeth

Because baby teeth are so delicate, more caution should be exercised when caring for them. Here’s how to look after your child’s teeth.

  • As soon as your baby’s first tooth appears, start brushing.
  • Always rub each tooth with a clean baby cloth dampened with warm water. You can also rub your gums to clean them.
  • Give your youngster a cold, wet towel to chew on. This can help with teething pain.
  • You can transition to a kid’s toothbrush once your baby’s teeth are mostly in. Make sure the toothbrush’s bristles are gentle. Make sure to get one with a small head so you can brush all of their teeth gently and properly.

How to Look After Your Teeth

Brushing and flossing your teeth on a daily basis is the best approach to keeping them healthy.

According to the American Dental Association and the American College of Prosthodontists,

  • Brushing for at least 2 minutes.
  • Position the toothbrush at a 45-degree angle so that it reaches the gums and teeth.
  • Giving special attention to the gums and molars
  • Wrap 16–18 lengths of floss over your fingers and gently thread it between your teeth until it hits the gums, moving it up and down.
  • Use a clean section of floss every two teeth.


Humans are expected to have a total of 52 teeth throughout their lives. 32 of these teeth are adult teeth, with only 20 being milk teeth. All of your adult teeth should be firmly established in your gums by the time you reach the age of 21. However, this isn’t always the case.
