What is dental pulp?
To understand root canal treatment, it helps to know first something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue and creates the surrounding hard tissues of the tooth during development.
The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root. The pulp is important during a tooth’s growth and d
evelopment. However, once a tooth is fully mature it can survive without the pulp, because the tooth continues to be nourished by the tissues surrounding it.
Functions of Tooth Pulp
Dental pulp has important functions to teeth health
The pulp has several important functions. Although the primary function of tooth pulp is the formation of dentin, it has several other functions as well.
Functions of tooth pulp include:
- Sensory Function – Pain from trauma to the dentin and/or pulp, differences in temperature, and pressure are caused by stimulation of the pulp.
- Formation of Dentin – The pulp is responsible for the formation of dentin In response to trauma, the pulp forms secondary dentin, also known as reparative dentin
- Nourishment – The pulp contains blood vessels that help to prevent the tooth from becoming brittle by keeping it moisturized and nourished.
