• Bacteria can enter the pulp through various routes, including:

• Bacterial toxins and enzymes stimulate an inflammatory response in the pulp

Trauma

• Blunt trauma to the tooth can cause pulpitis
• Examples of traumatic events include:
  • Falling and hitting the tooth
  • Being hit in the mouth
  • Biting or chewing on something hard
• Trauma can lead to bleeding and inflammation in the pulp

Corrosion or Erosion

• Improper dental procedures can cause pulpitis, including:
  • Over-instrumentation during root canal therapy
  • Over-preparation of the tooth during restorative procedures
  • Use of harsh chemicals or medicaments
• These factors can cause mechanical or chemical irritation of the pulp

Other Factors

• Genetic predisposition can contribute to pulpitis
• Systemic diseases, such as:
