How Many Teeth Does An Adult Have? The Shocking Answer

While most people know how many teeth they have or should have, the question asked most often is how many teeth does an adult have. It’s a number debated quite often among dentists and non-specialists alike.

The short answer is that adults have 32 teeth.

But, there’s a little more to it than that. There are three sets of permanent teeth in the adult mouth: incisors, canines, premolars, and molars. The first set emerges when we’re between 6 and 8 years old, and the second comes in around the time we turn 12. The third set comes in when we’re between 19 and 21 years old. And by the time we’re fully grown, our mouths house 32 permanent teeth.

Of course, we also have baby teeth—also known as deciduous teeth or milk teeth—that fall out as our adult teeth grow in. Kids usually have 20 baby teeth that emerge in pairs over six months. They usually start coming in at around six months of age, but they don’t all fall out until the child is between ages 5 and 7 years old. So the answer to how many teeth does an adult have is not straightforward.

Does Everyone Have 32 Teeth?

Many people think that everyone has 32 teeth. In reality, not everyone has 32 teeth. This is because of baby teeth and wisdom teeth.

Some people have 28 teeth, some have 25, some have 22, and some even have less than 22.

Many people have all their baby teeth, plus four more than they need. These additional teeth are called “wisdom teeth.” Wisdom teeth grow between the ages of 17 and 21 years old. Most people do not need these additional four teeth, so they get them removed to make room for the other teeth.

How Many Teeth Do Grown Adults Have?

Grown adults have 32 teeth. They have eight incisors, four canines, eight premolars, and 12 molars. The number of teeth does not change over time.

The average human adult has 32 teeth: eight incisors, four canines, eight premolars, and 12 molars. Wisdom teeth are a type of molar.

How Many Teeth Do Kids Have?

Apart from asking how many teeth does an adult have, people also wonder how many teeth do children have. When children are born, they don’t have any teeth. As they grow older, their teeth start to come in. The first teeth that appear in their mouths are called baby teeth or primary teeth. Over the next year or two, children will get more and more baby teeth until they have 20 primary teeth altogether.

The first baby tooth appears at around six months of age. It’s not uncommon for babies to get their first tooth closer to 3 months or even later than 12 months. In fact, it’s generally considered normal for a child’s first tooth to come in any time within this broad window.

The last baby tooth usually comes in around the age of 2½ years. A child may start losing their baby teeth as early as four years old. Baby teeth fall out to make room for permanent adult teeth that will take their place until the child reaches about age 21.

How Many Teeth Do Teenagers Have?

Another common question, apart from how many teeth does an adult have, is how many teeth teenagers have? Teenagers have 32 teeth. This includes two sets of molars, four wisdom teeth, and four canines.

Teenagers’ first set of teeth is called primary teeth or baby teeth. These are typically lost before adulthood and make way for the permanent set of teeth, known as adult teeth.

Can You Tell Someone’s Age by Looking at Their Teeth?

Brushing and flossing are a good idea, no matter how old you are—but there’s a point where it might be too late to fix the damage.

There’s been a bit of debate over whether or not someone can guess your age just by looking at your teeth. Some people believe that having nice, pearly whites makes you look younger, while if you have crooked or yellowing teeth, it makes you look older. While this may not be completely true all the time, some evidence suggests your teeth may give away more than just wrinkles ever could.

One study found that those who had “normal” looking teeth were often judged as being younger than they were. One dentist said that dental care is often one of the first things to go when people get busy with work and family. He also said that a person’s dental health could reflect their overall health because conditions like diabetes and gum disease can impact your smile and general health.

While brushing and flossing are still important for younger people, as you age, taking care of your oral hygiene becomes even more critical for maintaining your overall health. So no matter how old you are, make sure to take care of those pearly whites!

What Are Canine Teeth And How Many Do Adults Have?

Canine teeth are the four long, sharp teeth on either side of the upper and lower front teeth. Most adults have two canine teeth on each side of their top and bottom jaws. These are also called cuspids or eyeteeth.

Canines help tear apart food during chewing. They’re not exclusively in dogs; humans have them, too. They’re sometimes called fangs because a dog’s canines are longer and sharper than other animals’ canines.

What Are Molars And How Many Do Adults Have?

We all have molars, but do you know exactly what they are and how many you have? Molars are simply your back teeth. Adults have 12 molars. They’re rounded, flat teeth that have large surfaces for grinding food before it’s ready to be swallowed. The word “molar” comes from the Latin word for “millstone,” which is a large round stone used to crush grain. Molars are sometimes called wisdom teeth and are the last teeth to grow in, so they’re not present until you’re 16-25 years old.

You might need a root canal if one of your molars becomes infected, but this is rare. Chewing ice or biting down on hard candy can damage your enamel and cause sensitivity or cracking. You should also avoid chewing hard things like nuts or popcorn kernels since they can crack your teeth.

Do All Adults Have Wisdom Teeth?

The short answer is yes. Most people (about 90%) develop wisdom teeth. Wisdom teeth are the third set of molars on your mouth’s upper and lower sides, behind your other molars. They usually develop between the ages of 17 and 21.

Not everyone has enough room in their mouths for wisdom teeth to come in properly, though, which can cause pain and discomfort. In that case, you may want to get them removed.

When Do People Get Permanent Teeth?

The question of when people get permanent teeth is a surprisingly complicated one. According to the American Dental Association, the first permanent tooth usually erupts around age 6 or 7, and the last permanent tooth usually erupts in the late teens to early 20s. The eruption of the last four permanent molars is often referred to as “wisdom teeth,” though they are simply molars like any other.


The average human adult has 32 permanent teeth. Each tooth consists of a crown, which is the visible part of the tooth above the gum line, and the root, which is embedded in the jawbone. If you’re wondering how many teeth your mouth can hold, it turns out that your dental support system is quite accommodating. In fact, on average, an adult’s mouth will hold 32 adult teeth — four wisdom teeth included!
