What Are People’s Teeth Made Out Of?


You may have ever wondered what teeth are made of. Because it is such an important piece in your day to day, both for its function and aesthetic character, it is normal for you to wonder what teeth are made of.

In reality, it is not usual to know in depth the various parts of teeth, and there are even those who believe that it is just another bone. And in a way, it is normal for a parallel to be established since both teeth and bones have calcium, but they differ essentially in that teeth cannot regenerate and heal if they break.

Teeth are made up of different tissue layers, which give rise to the consistency, hardness, and resistance that characterize this essential element of the digestive process.

Our teeth begin to form during the embryonic phase of the fetus. Later, during the first months of life, this temporary dentition made up of 20 pieces is used so that the little ones can begin to chew the first foods. But it is after 6 years when the teeth are already made, and the permanent ones start to fall out and erupt.

To answer the question about what teeth are made of, we must take into account several factors. By themselves, teeth are bony pieces that grow in the mouths of humans and other living things. Its function is to cut and chew food to facilitate its intake.

Teeth are made up of dentin (or ivory), a particular type of very resistant yellowish bone tissue. It is the most abundant part of the tooth, and we find it within the enamel, being much more sensitive than this. Together with the cement, it helps protect the pulp or nerve. Helps nourish the tooth.


Its function is to protect the pulp from temperature variations and mechanical stresses. When we lose enamel, this part is exposed and can cause pain in contact with cold, very hot, sweet, or acidic foods.

Not by chance, teeth are the most mineralized organs in the human body. Dentin is a composite porous material:

  • 65% inorganic material;
  • 22% organic material;
  • 3% of water.

On the other hand, a fundamental element that complements teeth is tooth enamel, also known as adamantine tissue, which is a protective covering for the teeth. It is composed of hydroxyapatite, the hardest mineral found in the human body that we can also see, although to a lesser extent, in bones.

This mineral, added to the proteins in enamel, makes teeth pieces resistant and strong, with characteristics that allow them to face external agents throughout their lives, even with impeccable aesthetics. Of course, the above goes hand in hand with the care and attention that we pay to their health, starting with proper oral hygiene.

The enamel color has a translucent white or blue-gray hue. In addition, the color of teeth is determined by the dentin, an ivory layer that surrounds the teeth.

The dental crown, commonly known as a crown, is that visible part of the tooth. It is also common to hear a crown when we refer to the dental term of restoring the original one with a prosthesis when it is damaged. Colloquially we call it a dental cover.

What Are Teeth Made Of?


In addition to having elements such as tooth enamel, dentin, or crown, Teeth are made up of several elements. In this list, you can see what elements and what material the teeth are made of as long as you know our mouth a little more.

  • Enamel
  • Dentine
  • Crown
  • Pulp
  • Cement
  • Root
  • Periodontal membrane
  • Nerve and blood supply


Pulp or dental pulp is a loose connective tissue inside the tooth and is surrounded by dentin. In dentin, a small cavity (pulp cavity) contains the pulp of the tooth that is particularly rich in blood vessels and nerve endings (trigeminal nerve). It continues in a canaliculus that runs through each of the roots (root canal) and then flows into the socket with a small hole, through which blood vessels and nerves enter the tooth.

Inside it contains particular cells, the odontoplasts, which have the function of producing the dentin necessary for the renovation processes.

The sensitivity of the tooth is due to the presence of nerve endings within the dental pulp. Each tooth has tactile, thermal, and pain sensitivity.


It is a layer responsible for covering the root of the tooth. It is a tissue that has the same function as enamel but only covers the part covered by the gum or root, which is embedded in the bone and supported by a membrane called the periodontal ligament.


The root or tooth root is formed by dentin and covered by dental cement. It is connected to the alveolar bone (it is the bone located in the maxilla or mandible responsible for lining the spaces where the teeth’ roots are maintained), unlike the dental crown, which, as we have said, is covered by enamel. The part where the root and crown meet is known as the dental neck.

Periodontal Membrane

The periodontal membrane or periodontal ligament is a component that is part of the periodontium, responsible for providing sustainability. The different functions of the tooth can be carried out.

This set of collagen, elastin, and oxygen fibers are responsible for joining the teeth to the bone. In this way, it holds them inside the gum. This function is reinforced by the cementum or root cement and the alveolar bone, which also performs mechanical functions.

Nerve And Blood Vessel

In the blood vessel and nerve, we contemplate two elements. On the one hand, the blood vessel is a hollow structure that drives the heart’s blood. In this element, nutrients and oxygen are transported. The blood vessel of the tooth carries essential nutrients.

The nerves are located in the central part of the tooth. It is the most sensitive and indicative part that something inside our tooth is not working.

Seeing that teeth are made of so many different elements that we have in the human body, it is something so small that we do not give it importance until we have problems. Therefore, we recommend going to a dentist who has the best dental equipment periodically to obtain guarantees in our consultations.
