• Enamel: is the substance that covers the crown of the tooth.It is very hard and quite resistant to mechanical and chemical attack. Its purpose, of course, is to protect the tooth from the dangers posed to the teeth by the oral environment.
• Dentin: is the hard, yellow bone-like material that underlies the enamel, cementum and surrounds the entire nerve. is sensitive to touch and other stimuli.
• Gums: the soft tissue that surrounds the root of the tooth.
• Cementum: a layer of tough, yellowish bone like tissue that covers the root of a tooth. It helps to hold the tooth in the socket. the fibers of the periodontal membrane are embedded within the cementum.
• Pulp: the soft centre of the tooth. The pulp contains blood vessels and nerves; it nourish the dentin.
• Nerves: nerves transmit signals to and from the brain.This let you feels things like hot, cold and pain.
• Periodontal membrane ligament: the strong fleshy tissue between tooth and the tooth socket that holds the tooth in place,the fibers of the periodontal membrane are embedded within the cementum.
