If untreated, a pulp infection or any nerve tissue inflammation can be extremely painful and even result in the spread of the illness or tooth loss. It also does away with the requirement for a future dental implant and tooth extraction.
Anatomy
Knowing a tooth’s anatomy will help you better comprehend why a root canal is required. Three primary layers make up each tooth:
Enamel: The visible, firm, white exterior covering of the tooth is called the enamel.
Dentin: The dentin is the layer that lies beneath the enamel and constitutes most of the tooth.
The dental pulp: The Inner layer of soft tissue beneath the dentin, known as the dental pulp, contains blood arteries, nerves, and other tissue. It reaches from the tooth’s root to the end of the root canal.
