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.
