13 Oct How Many Teeth Do Humans Have? The Complete Guide

The teeth are an important part of the body. They shape our smiles, help us to chew food and pronounce words clearly. Have you ever wondered how many teeth we have? It depends on how old you are, as children and adults have different numbers of teeth.

This blog will explain how many teeth people have, the types of teeth they have and why knowing this is important for your health.

How many teeth do children have?

• The first 20 teeth of a child are called the primary teeth.
• Around 6 months of age, teeth begin to appear.
• Most children will have 20 teeth by the time they reach 3.
• The teeth are incisors and canines — but not premolars.
• The baby teeth are important in the placement of permanent teeth. These teeth also help children to eat solid food and speak clearly.

How many teeth do adults have?

Around age 6, adults usually have 32 permanent teeth. These teeth replace the baby teeth. Most people have all their adult teeth by the time they reach their early 20s, including their wisdom teeth.

The adult tooth is broken down into the following categories:

Incisors (eight):

Front, flat teeth, four on top and four on bottom, used to cut food.

Canines (four):

Sharp, pointed teeth used to tear.

Premolars (also called bicuspids)

These teeth are located behind the canines. They help chewing.

Molars (12 teeth):

Large flat teeth in the back of the mouth that are used to grind food. This includes the four wisdom teeth. The complete set of adult tooth is

8 incisors + 4 canines + 8 premolars + 12 molars = 32 teeth.

Do all adults have 32 teeth?

Not necessarily. Because wisdom teeth are removed, many adults have 28 or more teeth. Here’s why:

1. Crowding: Insufficient space in the jaw to allow wisdom teeth to properly grow.
2. Impaction: Wisdom tooths can grow in an angle or get stuck underneath the gums.
3. Infection or Pain: These infections can cause pain, swelling or cavities.

It is normal for some people to be born without wisdom tooth. Other people may lose their teeth because of injury, decay or gum disease.

When do humans get their permanent teeth?

1. Age 6-12: The baby teeth are lost and the permanent teeth begin to emerge.
2. The average person has 28 teeth (without wisdom tooth).
3. Between 17 and 25 years of age: Wisdom tooth usually appears, completing the total 32 teeth.

Why is the number of teeth important?

Understanding oral health requires more than a trivial knowledge of the number of teeth we have.
