How Many Teeth Do We Have? The Answer For Children & Adults

How Many Teeth Do We Have? On average, an adult has 32 teeth, including 8 incisors, 4 cutting teeth, 8 molars and 12 wisdom teeth (if any). However, the number and type of teeth can vary from person to person. For example, some people have complete wisdom teeth, while others have fewer than 32 teeth due to tooth loss or problems.

How Many Teeth Do We Have

Children typically develop 36 teeth, including 20 incisors, 8 canines, and 8 molars. Meanwhile, adults have 32 teeth, including 16 incisors, 4 h canine teeth, 8 h premolar teeth and 12 h molars.

There are a maximum of 32 teeth in a human mouth, however, this number varies from person to person and with physical maturation. Dentistry is the practice of diagnosing and treating oral health problems, such as

Below is a table comparing the number of teeth between children and adults, based on modern dental classification:

However, the total number of teeth in the human body is 32 teeth. There can be differences in the number of teeth for each person depending on the development of the body. Some people may be missing one or more teeth or have extra teeth, which need to be diagnosed and treated in dentistry.

Classification Of Teeth

The American Dental Association classifies teeth by size, form, location, quantity, and function. This article in the International Dental Journal describes the 4 different human tooth types (incisors, canines, premolars, and molars). Each tooth type aids in digestion and dental health.

Incisors (total 8 pieces)


Incisorsas, as known as front teeth, are rectangular-shaped teeth having a cutting edge. They are used to cut and bite food and are situated in front of the upper and lower jaws. There are 2 incisors on each side of the human jaw. From birth until roughly 8 years old, incisors are smaller than other teeth.

  • The incisors play a crucial role in both speech production and digestion. They facilitate the process of chopping food into manageable chunks for easier swallowing and digestion. Moreover, the incisors are crucial to correctly pronouncing the syllables of a language.
  • Incisor problems include bleaching-induced front tooth degeneration, bacterial sores and cavities, and others.

Thus, it is crucial to maintain the health of the front teeth and the complete oral system via daily oral hygiene and frequent dental checkups.

Teeth h Canine (Total 4 Pieces)


Canine teeth, sometimes called cuspids, have a conical apex called a cusp and are used to cut, rip, and grind food. There are 4 canine teeth on the human jaw, positioned between the incisors and premolars.

The development of canine teeth occurs between the ages of 11 and 12, and they are typically greater in size than the incisors and premolars. How your canine teeth are positioned affects more than just your bite and pronunciation. They participate in the chewing and digestion processes by aiding in the breakdown of tough food.

  • In addition, canine teeth also have an important role in keeping the position of other teeth. If a canine tooth is lost or not fully developed, the surrounding teeth can move out of place, causing problems with oral health.
  • Also, Canine teeth may also develop sores, cavities, and tooth wear.

Teeth h Premolar (Total 8 Pieces)


The premolar teeth, also known as semi-molars, are the teeth located between the canine and incisors in the human dentition. The human upper and lower jaws each have two h premolar teeth, a total of 8 h premolar teeth in the entire jaw.

As compared to the incisors and canines, the premolar h teeth are about medium size. The premolar teeth are responsible for chopping, crushing, and chewing food. An additional factor in establishing the shape of a person’s jaw and bite is the location of their premolar teeth.

If you have problems with your premolar teeth, such as tooth loss or toothache, see your dentist for a timely examination and treatment.

Teeth h Molars (Total 12 Pieces)


The molars are the largest and final teeth in the human dentition. The human upper and lower jaws each have 3 h molars, a total of 12 h molars in the entire jaw.

  • Crushing and chewing food is the major function of molars, which are bigger than other teeth. H molars feature multiple pointed segments on the tooth surface to help chop food.
  • The position of the molars in the jaw is also very important, these teeth are located at the back of the jaw and it is this position that gives them the best ability to grind and chew food. Unfortunately, their remote location makes tooth disorders common.

Supernumerary Teeth

Supernumerary teething is the eruption of extra teeth after all of the normal teeth have fully erupted. This is a common phenomenon and can happen to anyone, regardless of age. The number of supernumerary teeth depends on each specific case, usually from 1 to 4 teeth. The position of the supernumerary teeth can appear in many different places on the jaw, depending on each specific case.

Also, supernumerary teeth are often discovered during routine dental exams or when patients experience discomfort, pain, or inflammation around the tooth. In this case, the dentist can carry out whitening, a root canal or extra tooth extraction if necessary.

Newborn Teeth

Newborn Teeth

Children get their first teeth between 6 and 12 months old. Newborn teeth consist of 20 teeth, divided into 2 types: baby teeth and permanent teeth.

  • Baby teeth include 8 cutting teeth (4 upper cutting teeth and 4 lower cutting teeth) and 12 chewing teeth (8 molars and 4 chin teeth). All baby teeth will fall out to make way for the growth of permanent teeth.
  • In terms of position, newborn teeth will grow from bottom to top, starting from the upper and lower cut teeth, then the molars and finally the chin teeth. When baby teeth begin to fall out, permanent teeth will erupt to replace them.

It’s important to take care of your baby’s newborn teeth from the moment they appear to make sure their baby teeth and permanent teeth grow strong and healthy later on.

What If You Lost Your Teeth?

Tooth loss is a serious problem in the field of dentistry. There are many causes of tooth loss, including trauma, tooth decay, periodontal disease, gingivitis, and aging. The loss of teeth seriously affects the health and quality of life of patients.

Besides, missing teeth can lead to negative health effects such as:

  • Affects chewing function: Losing teeth makes chewing harder, reducing vitamin absorption and compromising health.
  • Changes in jaw structure: As a tooth is lost, jawbone pressure decreases, causing bone loss and facial changes.
  • Disrupts speech and pronunciation: Missing or missing teeth can cause speech and pronunciation problems, affect communication, and create low self-esteem.
  • Impact on psychology and self-confidence: Losing teeth can affect a patient’s psychology and self-confidence, leading to communication difficulties and affecting the quality of life.

But, you don’t need to worry. To prevent and treat tooth loss, dental measures can be applied, including dental implants, bridges, scaling, fillings and braces. However, regular dental care and adherence to the principles of proper oral hygiene are the best ways to minimize the risk of tooth loss and preserve the overall health of your teeth.

Tips For Healthy Teeth And Dental Care

Taking good care of your teeth and gums is a crucial aspect of avoiding dental disease and preserving your oral health. Tips from Spring Orchid’s dentist on how to keep your teeth healthy and avoid losing any of them:

  • Brush properly: Clean your teeth twice daily for 2 minutes. Use a medium-hard toothbrush and brush according to tooth form. To eliminate plaque and germs, brush all angles.
  • Flossing: Daily flossing is recommended. Flossing removes plaque and food between teeth.
  • Use mouthwash: An effective mouthwash may kill off lingering germs and significantly reduce foul breath. Using mouthwash at least once a day is recommended.
  • Limit sweets and carbonated drinks: Sweets and carbonated drinks can cause bacteria growth and acids in the mouth. Limiting sweets and fizzy drinks can help reduce the risk of tooth loss.
  • Treat dental problems promptly: You should have dental work done as soon as you notice anything wrong. If dental issues are caught early, they may be treated before they worsen and cause loss of teeth.
  • Routine dental visits: It is suggested that you see your dentist at least twice a year to check on your oral health and get oral care advice. Frequent dental appointments are also beneficial.

Why do children have 32 fewer teeth than adults?

As a result of how their mouths grow, kids typically lack 32 permanent teeth whereas adults only lack 7. Children’s primary teeth (sometimes called milk teeth) fall out at this stage of development and are eventually replaced by permanent teeth. Permanent teeth begin to erupt into position between the ages of 6 and 12, in accordance with the principles of oral development.

Depending on the incisor and molar development, the number of teeth will rise from 20 to 32. Children’s teeth are less than adults’ because they don’t have enough room in their mouths to grow all their permanent teeth.

How many baby teeth fall out?

Infant’s teeth emerge from the roots between the ages of 6 months and 1 year. As the permanent teeth develop between the ages of 6 and 12, the youngster may begin to lose their baby teeth.

According to the American Dental Association, a typical youngster loses roughly 20 baby teeth, including 10 upper and 10 lower teeth. Baby teeth often fall out in the following order: top and bottom two front teeth, then posterior molars, and lastly rear incisors. Baby teeth fall off, making room for permanent teeth.

Can we self-treat cavities or gingivitis?

Don’t try to do dental work on yourself. You should not attempt to treat a dental condition on your own because you might make it worse, leading to more damage to your teeth and gums and perhaps even more serious complications including infection and swelling.

To detect and correct problems and keep your teeth healthy, see your dentist often.
