This treatment is applied when the nerve (pulp) inside the tooth is damaged or dies due to decay or trauma. The procedure involves removing the nerves inside the tooth, shaping the canals in the roots, disinfecting them from microorganisms, and then filling the enlarged canals. Afterwards, restorations such as fillings, porcelain, crowns, or inlays are performed by the dentist according to the loss of substance in the upper part of the tooth to maintain functional continuity. Otherwise, the tooth may need to be extracted.

The most common causes of pulp damage are:

• Cracked tooth
• Deep decay
• Tooth injury caused by a severe blow in the past or recently

Additionally, various techniques are used in vital treatments to keep teeth alive in the mouth:

• Permanent tooth capping
• Extraction of baby teeth
