1. Sensation: The pulp contains nerve fibers that provide sensation to the tooth, allowing us to feel hot, cold, and pain. 2. Nutrition: The pulp supplies nutrients to the tooth, helping it to stay healthy and function properly. 3. Formation of dentin: The pulp is responsible for producing dentin, the hard tissue that makes up the majority of the tooth structure. 4. Defense: The pulp contains immune cells that help fight against infection and inflammation in the tooth. 5. Repair: In response to injury or decay, the pulp can initiate a repair process by forming secondary dentin to protect the tooth. 6. Blood supply: The pulp contains blood vessels that supply oxygen and nutrients to the tooth, promoting its overall health. 7. Development: During tooth development, the pulp plays a crucial role in the formation and maturation of the tooth. 8. Sensory feedback: The pulp provides feedback to the brain about the position and pressure applied to the tooth, helping us to chew and bite effectively.
