The tooth structure is composed of multiple layers, each serving a specific function to protect and support the tooth's integrity. These layers include enamel, dentin, pulp, and cementum, working together to facilitate chewing, protect against decay, and support overall oral health.

Enamel is the hardest substance in the human body, primarily composed of hydroxyapatite, and serves as the protective outer layer of teeth. Its durability and resistance to decay are crucial for maintaining oral health, though it cannot regenerate once damaged.

Dentin is a calcified tissue that lies beneath the enamel and cementum in teeth, providing structural support and protection to the inner pulp. It is composed of microscopic tubules that can transmit sensations such as pain and temperature changes to the dental pulp.

dentin

Pulp refers to the fibrous material obtained from wood, recycled paper, or other plant sources, used primarily in the production of paper and paperboard. It plays a crucial role in the paper industry, impacting both the quality of the final product and the sustainability of the production process.

pulp

Cementum is a specialized calcified substance covering the root of a tooth, playing a crucial role in anchoring the tooth within the alveolar bone by attaching to the periodontal ligament. It is essential for maintaining the integrity of the tooth's attachment system and can undergo continuous deposition throughout life to compensate for tooth wear and movement.

cementum

Chewing is a fundamental biological process that involves the mechanical breakdown of food in the mouth, making it easier to swallow and digest. It also plays a crucial role in the initial stages of digestion by mixing food with saliva, which contains enzymes that begin the chemical breakdown of carbohydrates.
