Structure of a tooth
Enamel:The hard outer layer of the crown. Enamel is the hardest substance in the body.
Dentine:Not as hard as enamel, forms the bulk of the tooth and can be sensitive if the protection of the enamel is lost.
Pulp Soft tissue containing the blood and nerve supply to the tooth. The pulp extends from the crown to the tip of the root.
Nerves and blood supply: Each tooth and periodontal ligament has a nerve supply and the teeth are sensitive to a wide variety of stimuli. The blood supply is necessary to maintain the vitality of the tooth.
Bone: Provides a socket to surround and support the roots of the teeth.
Crown : the top part of the tooth, and the only part you can normally see. The shape of the crown determines the tooth's function. For example, front teeth are sharp and chisel-shaped for cutting, while molars have flat surfaces for grinding.
Root: the part of the tooth that is embedded in bone. The root makes up about two-thirds of the tooth and holds the tooth in place.
Neck:The narrowed part of a tooth between the crown and the root.
