  19. 4 免疫因素

  20. PULP AND JAW INFECTION Bacteria are the most common causes of inflammation and infection of the pulp. They usually enter the pulp through tooth decay (caries). Invading bacteria first overwhelm the natural defences in the pulp chamber. Then they destroy the tissues in the root canal(s).

  21. Toxins (poisons) from the bacteria that have destroyed the pulp can leak out through the apex into the jawbone. The jawbone, like all bones, is a living tissue which has arteries, veins, and nerves. Therefore, it can become inflamed and infected by the presence of bacteria and their toxins.

  22. INFECTION OF THE FACE AND NECK If untreated, infection in jawbone can erode through the side of the bone into the mouth, or even into the face or neck, and cause sudden, serious, and painful swelling.
