how many teeth do humans have 36

Have you ever wondering how many teeth you have? Well, it’s your lucky day. Because we’re going to dive into the answer. The truth is that the number of teeth you have depends on a few factors: age and the presence of certain conditions. As you may know, children and adults actually have different sets of teeth, and the number of them varies. As you read on, we’ll look into the differences between children and adult teeth as well as the conditions that affect the number of teeth you have.

Baby Teeth

Children begin teething around six months of age, meaning that their teeth start coming in around that point. These first teeth are known as baby teeth, primary teeth, or, technically, deciduous teeth. As you know, they eventually fall out and are replaced by adult teeth.

How many teeth do children have? Children have 20 baby teeth. That includes 10 teeth on the top and 10 teeth on the bottom. All 20 of them usually come in before the age of three and act as placeholders for the adult teeth that grow in after the baby teeth fall out. At about age six, most children begin to lose their baby teeth, which are then replaced with adult teeth. This process continues until kids reach their early teen years.

It’s important to mention that just because baby teeth fall out doesn’t mean that they don’t need care like adult teeth. Oral care routines should begin before a baby’s first tooth comes in. This can be done by running a clean, damp washcloth over the baby’s gums. Once the first tooth comes in, parents can brush the baby’s teeth with an infant toothbrush and a tiny bit of toothpaste. Flossing can begin once the baby’s teeth touch.

Adult Teeth

When adult teeth come in, there’s more room in the mouth and more teeth. How many teeth do adults have? Most adults have 32 teeth, which is 12 teeth more than children! Among these 32 teeth are 8 incisors, 4 canines, 8 premolars, and 12 molars, including 4 wisdom teeth. It is very common for adults to have their wisdom teeth removed because there is not always enough room for them to grow in comfortably or without causing misalignment of other teeth. Most people have a complete set of adult teeth by the time they reach their teenage years.

Conditions That Affect The Number of Teeth

Tooth loss is a surprisingly common condition. And periodontal disease (aka gum disease) is the main reason adults lose their teeth. Luckily, prevention is possible. It involves brushing twice a day and flossing daily.

Other reasons for tooth loss include:

  • Tooth decay
  • Ectodermal dysplasia (a genetic disorder that can affect teeth)
  • Gastrointestinal reflux (severe tooth erosion which causes stomach acid to come up into the mouth)

Beyond tooth loss, there’s also a condition called tooth agenesis, where teeth are missing in the mouth. It can either appear as the absence of all teeth or as 1 to 6 or more teeth missing. This condition is genetic and rare.

There are also circumstances where extra teeth, or supernumerary teeth, appear in the mouth. The most common type of supernumerary tooth is an extra incisor located between two central incisors.

Now you know the deal about how many teeth we have. Typically, children have 20 teeth, and adults have 32 teeth (28 if the wisdom teeth are removed). Remember that each one of them needs your care, even baby teeth. There are some cases where the number of teeth varies, resulting from tooth loss, tooth agenesia, or having extra teeth. So keep up with your oral hygiene no matter how many teeth you have. It’ll help make sure your teeth stay healthy and happy.


People typically find their last four molars, or wisdom teeth, erupt between the ages of 17 and 21. Between the ages of 18 and 25, the last 4 molars begin to appear in the 4 furthest corners of your mouth, which are your wisdom teeth. When you get your first teeth, and within the first few years of your life, you will have eight molars.


Most people will have eight incisors and four canines with deciduous (milk) teeth and permanent teeth. Since you have one on each side of your upper and lower incisors, you will usually have four canines. Eight incisors (the top four are slightly pointed teeth located on the sides of the incisors.

Two fangs

At the top you will see four incisors, two fangs, two fangs and four incisors are mainly used for chewing food. The teeth at the front of the mouth (incisors, canines, and premolars) are ideal for grasping and breaking food into smaller pieces. When cutting and tearing food, fangs ensure that the upper and lower rows of teeth do not collide. The 12 molars are used to grind and chew food to make it easier to swallow and digest.

12 Molars

In total, there are 12 molars in the adult dentition, six of which are located on the upper and six on the lower, both upper and lower jaws. The adult dentition consists of 8 premolars located between the permanent canines and permanent molars. Premolars are the teeth that differentiate your perm from your child’s dentition. The premolars are considered transitional teeth and guide food from the canines to the back molars for chewing.


Premolars are large, wide teeth that crush and grind food when eating. Adding premolars and third molars to permanent teeth increases the number of teeth with age. Baby teeth are gradually lost, and adults may have as many as 32 permanent teeth. As we age and our lower jaw begins to develop, 20 baby teeth are eventually replaced by 32 adult permanent teeth, 16 in each of the upper and lower jaws.

Adult teeth

Adult teeth will continue to erupt, replacing these lost teeth and filling in extra spaces in the mouth until the child is a teenager. Most children will have about 20 teeth before adults begin to erupt: 10 at the top and 10 at the bottom. On average, babies have 20 teeth at the age of six months, and the first adult teeth begin to appear between the ages of five and seven. This means that an adult will have 16 teeth in the lower and upper rows.

28 teeth

Of these 28 teeth, each has 14 in the upper jaw and 14 in the lower jaw. Of these, 16 teeth are located in the upper jaw (maxillary arch) and 16 are located in the lower jaw (mandibular arch). You have to open a little more to see the eight premolars, but when you do, you will notice that they are completely different in shape than the incisors and canines. Four are located next to the canine teeth, and the second molar is located next to the first.

Wisdom teeth

There are a variety of reasons for this, such as a total of four that didn’t fully erupt (or entered through the gums), they didn’t have enough room in their jaws, or other teeth were preventing the wisdom teeth from erupting. Usually, permanent teeth pass through the gums behind the last deciduous tooth in the lower jaw. If a person needs to have their wisdom teeth removed, the number of permanent teeth may drop from 32 to 28, as it is more common to have all four wisdom teeth removed at the same time. A complete set of adult teeth includes 8 incisors, 4 canines, 8 premolars, and 12 molars; however, this total assumes that the adult in question has 4 wisdom teeth and retains all of them.

Third Molars

The vast majority of people in the United States have 4 wisdom teeth (or third molars) pulled out during adolescence, leaving the average American with 28 teeth. Most often, adults have 28 teeth, as they often have to remove wisdom teeth due to alignment or inclusion problems (in the mouth of modern people, there is often not enough room to accommodate four additional molars). Babies usually only have 20 teeth after their milk teeth have run out, as their mouths are not yet big enough to hold all the teeth they will need when they become adults.

20 baby teeth

You should also know that there are 20 baby teeth compared to 32 adult teeth, which means there are 12 teeth that don’t have baby teeth in front of them, and it’s okay if you see more than 20 teeth in your child’s mouth at that time. from 6 or 7 years old. These milk teeth persist until age 6 or 7 when the first permanent tooth begins to appear, i.e. the first permanent molar that appears behind all of these teeth (meaning that this particular molar did not have a milk tooth before and therefore does not will appear). another discordant tooth). Babies have 20 milk teeth (or atuffers, depending on how cute they are) aten on the top and ten on the bottom, which usually begin to be lost at the age of six.
