What are the Different Parts of the Tooth?


The teeth are a component of the digestive system in your body. Before you swallow, they reduce the size of the food by either crushing or chopping it. The average number of teeth found in a human is 32, but some people have more and others have fewer. The enamel that covers the outside of your teeth serves as a protective barrier and is the hardest substance in the human body.

What are Teeth?

Your teeth are very important to the digestive process. By chopping and crushing the food, they make it more manageable for the patient to swallow.

Teeth are ectodermal organs, despite their appearance, which are more similar to that of bones. Your hair, skin, and sweat glands are all examples of different ectodermal organs.

How Many Teeth Do Humans Have

The average adult has 32 teeth that never fall out. However, some people are born without teeth (a condition known as hypodontia), while others have extra teeth (a condition known as supernumerary teeth).

The majority of children have twenty primary teeth, or baby teeth, that erupt (come in) between the ages of four months and six years. These are temporary teeth, also known as baby teeth, which will be replaced by permanent adult teeth at some point in the future.

What are the Four Types of Teeth?

There are many distinct kinds of teeth, each one serving a specific function essential to our health. The following are the four categories of human teeth that are permanent:

  • Incisors
  • Canines
  • Premolars
  • Molars

1. Incisors

In front of the other teeth in your mouth, your incisors are the ones that stand out the most. The upper jaws of most people have four incisors, and the lower jaws also have four incisors. These consist of your two front teeth as well as the teeth that are located on either side of them.

When you bite into something, the single, pointed edge of each incisor helps you cut through the substance.

2. Canines

Canine teeth got their name from the fact that they look like the fangs of a dog. They differ from other types of teeth in that they have more points. Canine teeth are typically located in each of the four corners of a person’s mouth (upper right, upper left, lower right, and lower left).

Canine teeth are useful for tearing into tough foods like meat and vegetables with a crunchy texture. Canines are sometimes referred to as “eye teeth” because of their location directly under the eyes of a person’s mouth.

3. Premolars

Premolars, which are located in the space between your canines and your molars (the teeth at the very back of your mouth), are also referred to as bicuspids.

Premolar teeth are similar to canine teeth and molar teeth in appearance. They facilitate the ripping, crushing, and grinding of food into more manageable chunks.

4. Molars

The back teeth known as molars are located at the very back of your mouth. This is where approximately 90 percent of your chewing action takes place. The majority of adults have 12 molar teeth, with three located in each of the four quadrants.

Molar teeth are comprised of wisdom teeth, also known as third molars. Therefore, if you did not have your wisdom teeth extracted when you were younger or if you were born without them, you most likely have eight molars in total.

Your molars are the teeth that do the majority of the chewing, so they are ideal for crushing and grinding the food you eat.

How do Teeth Function?


The cutting, tearing, mixing, and grinding of food that you eat requires the coordinated efforts of all of your teeth working in harmony. After that, your tongue and your oropharynx (the upper part of your throat) work together to roll the food into a compact ball that is simple to swallow.

What’s the Anatomy of a Tooth? 

Two primary components make up a tooth:

1. Crown

This portion of your tooth extends above your gums and is the only part of your tooth that is visible. Your tooth crown is covered in enamel, a substance that is both hard and protective.

2. Root

This portion of your tooth is responsible for securing the tooth within your jaw. Because your gums cover it, you are unable to see the actual root. Your tooth is anchored to your periodontal ligament, which is the soft connective tissue that lines your tooth socket. The root is located at the center of the tooth.

What Are Teeth Made of?

The following are the four primary layers that make up your teeth:

1. Enamel

This is the layer that acts as a barrier between the inside and outside of each tooth. Your enamel acts as a barrier between cavity-causing bacteria and your teeth. The hardest substance found in the human body is called enamel.

2. Dentin

There is a layer of dentin just below the enamel that covers your teeth. Dentin isn’t as strong as enamel. When enough enamel is missing to expose dentin, the likelihood of developing cavities increases.

3. Cementum

Cementum covers your tooth root. Along with your periodontal tissues, it helps anchor your tooth firmly in your jaw.

4. Tooth Pulp

This is the layer of your tooth that is closest to the pulp. Nerves, blood vessels, and connective tissues are all found within its structure.

Are Teeth Bones?

No. Even though teeth are very similar to bones, they are very distinct from one another. When bones are broken, they can regenerate or repair themselves. Teeth are unable to. Your teeth, in contrast to your bones, do not have any marrow in them.

What Are the Common Conditions that Can Affect Your Teeth?

The majority of people have some form of tooth decay at some point in their lives. Cavities have the potential to develop when bacteria eat through the tough, outer layer of enamel on your teeth. The bacteria will continue to erode your tooth even after the dentin layer beneath it has been stripped of its protective layer.

Other common problems that can affect your teeth are the following:

1. Bruxism or Tooth Grinding

The enamel on your teeth can be worn away by clenching and grinding your teeth, making your teeth more vulnerable to damage.

2. Tooth Sensitivity

Teeth that are sensitive to heat and cold are typically caused by enamel that has worn away or roots that are exposed.

3. Trauma to Your Mouth

Accidents involving motor vehicles, sports-related injuries, and other forms of trauma can result in broken, chipped, or even knocked-out teeth.

4. Tooth Discoloration

It is natural for certain foods and beverages, like tea, coffee, or berries, to stain your teeth after prolonged consumption over time. Several medications, particularly long-term use of them, have been linked to tooth discoloration.

5. Impacted Teeth

If a tooth does not erupt properly, it can become impacted either in the gums or the jaw bone. Even though it can happen to any tooth, the most common instance of this is when the wisdom teeth become impacted.

6. Orthodontic Misalignment

Incorrect orthodontic alignment can manifest itself in a variety of ways, including crooked, gapped, crowded, or rotated teeth. These conditions can have a detrimental effect on both your oral health and your ability to chew food properly.

7. Abscessed Tooth

There are instances in which bacteria penetrate the pulp, which is the deepest layer of your tooth. If this occurs, you run the risk of developing an abscess, which is a painful pocket of pus.

8. Gum Disease

Even though gum disease first manifests itself in the gums, it can ultimately result in loose teeth and even the loss of teeth.

How Can You Keep Your Teeth Healthy?

The importance of good dental hygiene cannot be overstated because it is required to keep one’s teeth and gums healthy. Without the appropriate care, tooth decay and gum problems can lead to a variety of complications, some of which can ultimately result in pain, difficulties in speech, and a reduction in one’s sense of self-confidence. Many professionals believe that problems with dental health contribute to the burden that is placed on the global health system and that they must be addressed appropriately.

Observing good dental hygiene and preserving the health of your teeth are both goals that are well within your reach if you keep the following in mind:

1. Brush your teeth consistently to maintain good dental hygiene.

Brushing your teeth at least twice per day is one of the most important things you can do to keep your mouth clean and your teeth healthy. Plaque and bacteria can be removed from your teeth by brushing them. 

It is important to brush your teeth at least twice a day, but you should avoid doing so too vigorously. Brushing too vigorously can cause damage to the tooth enamel as well as the gums. It is recommended that you use toothbrushes that have gentle bristles.

2. To maintain good dental health, you should also brush your tongue.

It is important to remember to brush your tongue in addition to your teeth because plaque can also accumulate there. That can be accomplished in a variety of different ways. A tongue scraper, a spoon, or even the back of your toothbrush, provided it has a scraping edge, can be used to remove tongue plaque.

3. Consider whether or not you need to use products containing fluoride to keep your teeth in healthy condition.

Cavities can be avoided with the use of fluoride, and tooth decay can be brought on by a lack of fluoride. Fluoride is an antimicrobial agent that also acts as a barrier that protects your teeth from harmful bacteria. It is important to maintain good oral hygiene and tooth health by brushing your teeth twice a day with fluoride-containing toothpaste. Doing so will help promote oral hygiene and keep your teeth healthy.

Inquire about the necessity of purchasing a mouthwash that contains fluoride from your dentist, or consider looking into other available choices, depending on the nature of the problems you are experiencing with your teeth.

4. To keep up with proper dental hygiene, floss at least once per day.

Plaque and bacteria can be removed from between the teeth, an area that cannot be reached by the toothbrush, but can be with floss. It is just as important to floss as it is to brush your teeth because flossing removes food particles stuck between the teeth, stimulates the gums, and reduces inflammation.

5. Rinsing your mouth with mouthwash will help you keep your teeth clean and healthy.

Mouthwash can help improve dental hygiene by lowering the amount of acid that is produced in the mouth, re-mineralizing the teeth, and cleaning areas that cannot be reached by a toothbrush or by flossing. In addition to brushing and flossing, using mouthwash, which contains active ingredients, is an important part of good oral hygiene.

Only your teeth, which make up only about a quarter of your mouth, can be cleaned by brushing. Mouthwash, on the other hand, not only cleans the entirety of your mouth but also kills germs around and below the gum line, providing the highest level of cleanliness and protection possible.

6. Be mindful of what you put in your mouth to protect and preserve your teeth.

Your diet affects your oral hygiene and plays a role in the maintenance of the health of your teeth. Make sure that your diet is well-balanced by eating a lot of vegetables and fruits, foods that are high in starch, and foods that are high in protein, but cut back on foods that are high in sugar and fat.

7. Watch what you drink, too!

Drinking sugary beverages will almost certainly harm your teeth. Drinking sugary beverages regularly can cause cavities in your teeth. Additionally, they may contain high concentrations of acid, which can cause tooth erosion.

8. To maintain good dental health, you should avoid foods and beverages that are colored as well as cigarettes.

The state of your dental hygiene can also be impacted by smoking. Smoking leads to increased levels of plaque and tartar on the teeth if the germs remain there for an extended period.

Consuming colored foods has the same effect on the color of your teeth as smoking does, giving the impression that your teeth are dirty and lacking in vitality.

9. Visit your dentist consistently to ensure you have good dental hygiene.

Don’t skip out on your routine visits to the dentist if you want to keep up with your oral hygiene and get the input and recommendations of a trained professional. A dentist is qualified to evaluate and diagnose any problem that calls for prompt treatment to prevent it from becoming more severe. In addition, by performing a more in-depth cleaning on the teeth, your dentist will be able to remove any tartar that has formed on the plaque.


You will gain a better understanding of the causes of oral health conditions if you familiarize yourself with the basics of tooth anatomy. There are four primary categories of teeth, each of which serves a distinct purpose, such as biting, chewing, or grinding food. Every single tooth is comprised of several separate components, each of which plays a specific function. If you want to have a healthy smile, it is important to take care of this complex system.
