Pulp is the living tissue inside your teeth that contains blood vessels, nerves and connective tissue. It’s important for two main reasons: it helps to keep your teeth healthy and strong, and it provides sensation (feeling) to your teeth.

The pulp extends from the crown of the tooth (the part you can see) to the root of the tooth, which is anchored in your jawbone.

 There are a few different ways that pulp can be damaged, including:

Decay: This is when bacteria in your mouth form acids that eat away at tooth enamel, eventually reaching the pulp.

Trauma: A blow to the mouth or teeth can damage the pulp, even if there’s no visible damage to the tooth.

Infection: If decay isn’t treated and bacteria continue to grow, they can infect the pulp.

Pulp damage is usually treated with a root canal procedure, which involves removing the damaged pulp, cleaning out the inside of the tooth and then sealing it. In some cases, a tooth with damaged pulp may need to be extracted (pulled).

Functions of Dental Pulp:

The dental pulp has several functions. These include:

  • To provide sensation to the tooth. The dental pulp contains nerves that allow you to feel hot, cold, sweet or sour stimuli.
  • To provide nutrients to the tooth. The blood vessels in the pulp supply the tooth with nutrients that are necessary for its growth and development.
  • To help form the tooth. The cells in the pulp are responsible for helping to form the dentin, which is the hard, outer layer of the tooth.
  • To protect the tooth. The pulp acts as a barrier to bacteria and other harmful substances that could potentially damage the tooth.

If the pulp is damaged, it can no longer perform these functions. This is why it’s important to get prompt treatment for any dental problems that you may have.


The pulp is a very important part of your teeth. It helps to keep them healthy and strong, and provides sensation to your teeth. If the pulp is damaged, it can lead to serious dental problems. Therefore, it’s important to get prompt treatment for any dental problems that you may have.



1. Can Pulp regenerate?

Pulp regeneration is the process where new pulp tissue is formed to replace lost or damaged pulp. This can happen through various means, including:

  • Direct cell division of existing pulp cells
  • Migration of cells from the surrounding periodontium (jawbone and supporting tissues) into the pulp
  • Differentiation of stem cells into new pulp cells

Pulp regeneration is a complex process and is not yet fully understood. However, it is clear that the body has a remarkable ability to regenerate lost or damaged tissue, and this includes the pulp of teeth. With advances in dental technology and our understanding of the biology of tooth regeneration, it is likely that even more effective methods of pulp regeneration will be developed in the future.

2. What is Dental Pulp made of?

Dental pulp is made up of connective tissue, blood vessels, and nerves. The cells that make up the pulp are called pulp cells or odontoblasts. These cells produce the hard tooth substance (dentin) that makes up the bulk of the tooth. Dental pulp also contains other cell types, including:

Fibroblasts: These cells produce the collagen and other proteins that give the pulp its structure.

Macrophages: These cells help to protect the pulp from infection by ingesting bacteria and other foreign material.

Mast cells: These cells release histamine and other chemicals that can cause inflammation.

Neutrophils: These cells are a type of white blood cell that can help to fight infection.

3. Can a tooth survive without Pulp?

A tooth can survive without pulp because the tooth is mostly composed of dentin, which does not require a blood supply. Dentin is produced by the odontoblasts, which are located in the dental pulp. Once the odontoblasts mature, they move out into the dentin and lose their connection to the blood vessels in the pulp.

This means that the pulp is not essential for the survival of the tooth. However, the pulp does play an important role in the health of the tooth by providing nutrients and oxygen to the surrounding tissues, and by helping to protect the tooth from infection.

4. What happens if Dental Pulp becomes damaged?

If dental pulp becomes damaged, it can lead to pain, infection, and tooth loss. The most common cause of pulp damage is dental decay, which occurs when bacteria in the mouth produce acids that eat away at the tooth enamel. Once the enamel is breached, the bacteria can access the dentin and eventually the pulp. Dental trauma or procedures such as root canal therapy can also damage the pulp.

If the pulp is damaged, it will become inflamed and can become infected. This can lead to pain, swelling, and tenderness. If left untreated, an infection in the pulp can spread to other parts of the tooth or even to other parts of the body. In severe cases, this can be life-threatening. Treatment for a damaged or infected pulp usually involves removing the pulp tissue through a procedure called root canal therapy. After the pulp is removed, the tooth can be sealed and protected with a filling or crown.
