Tooth Layers
Teeth consist of multiple specialized layers. The outer enamel, the hardest substance in the body, protects against decay and damage. Beneath lies dentin, a bone-like tissue containing microscopic tubes that transmit sensations. The innermost pulp contains blood vessels, nerves, and connective tissue providing nutrients and sensation. Each layer serves specific functions in tooth structure and maintenance.
Root System
Tooth roots anchor into the jawbone through periodontal ligaments, providing stability while allowing slight movement during chewing. Cementum covers the root surface, helping attach periodontal fibers to the tooth. The root canal system within each tooth carries blood vessels and nerves from the pulp to the jaw. This anchoring system distributes chewing forces effectively while maintaining tooth vitality.
Supporting Structures
Teeth rely on surrounding tissues for support and function. Gums (gingiva) protect roots and bone from bacteria, while alveolar bone provides structural support. Blood vessels and nerves enter through small openings at root tips, ensuring continuous nourishment. This complex support system enables teeth to withstand significant forces during chewing while maintaining their health and position. Shutdown123
