How is pulpitis caused?

Pulpitis is a common dental disease primarily caused by various factors: 1. Bacterial infection: Bacteria are the main causative agents of pulpitis, especially facultative anaerobes and obligate anaerobic bacteria, such as Actinomyces, Streptococcus, and Lactobacillus. When teeth develop caries, cracked tooth syndrome, severe attrition, or other conditions, bacteria can invade the pulp through exposed dentinal tubules or other pathways, leading to infection. 2. Physical and chemical irritation: Physical or chemical stimuli resulting from dental trauma, tooth wear, or improper management during dental treatments (such as cavity preparation or filling) may also cause pulpitis. 3. Dental diseases: If dental conditions such as caries or periodontitis are left untreated, the病变 may gradually progress and affect the pulp, leading to the development of pulpitis. Therefore, maintaining good oral hygiene, timely treatment of dental diseases, and avoiding unnecessary irritation to the teeth are important measures for preventing pulpitis.
