### What is Pulp Necrosis? Pulp necrosis is a condition where the soft tissue inside a tooth, known as the pulp, dies. This condition is irreversible and is the final stage of a disease called pulpitis. ### Causes of Pulp Necrosis The pulp inside your teeth can die due to various reasons, including: - **Tooth Decay**: Severe cavities can reach the pulp and cause infection. - **Injury**: Trauma to the tooth can disrupt the blood supply to the pulp, leading to its death. ### Symptoms - **Pain**: The first sign is usually discomfort or pain, which can range from mild to severe. - **Discoloration**: The affected tooth may change color, starting from yellow to gray and eventually black. ### Diagnosis Dentists use several tests to diagnose pulp necrosis: - **Endo-Ice Test**: A cold spray is applied to the tooth to check for sensitivity. - **Hot Test**: Heat is applied to the tooth to see if it responds. - **Electric Pulp Test (EPT)**: An electrical current is used to measure the vitality of the pulp. ### Treatment - **Root Canal**: The infected pulp is removed, the chamber is cleaned, and the tooth is sealed and covered with a crown. - **Extraction**: If the tooth cannot be saved, it may be removed and replaced with an implant or bridge. ### Prevention Good dental hygiene, including regular brushing and flossing, can help prevent pulpitis and pulp necrosis. A healthy diet rich in vitamins and minerals is also essential. If you play contact sports, consider using a mouthguard to protect your teeth from trauma.
