Tooth destruction from processes other than dental caries is considered a normal physiologic process but may become severe enough to become a pathologic condition. Attrition is the loss of tooth structure by mechanical forces from opposing teeth. [66] Attrition initially affects the enamel and, if unchecked, may proceed to the underlying dentin.
The tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth and is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [3] The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [3]
During this stage of odontogenesis, the epithelial tooth germ forms a bell-shaped structure in the labio-lingual section and is characterised by the formation of the dental sac. The peripheral cells of the dental papilla undergo differentiation, growing larger in size and taking a columnar (uni-layered) form and are now referred to as ...
Pulp acts as a security and alarm system. Slight decay in tooth structure not extending to the dentin may not alarm the pulp, but as the dentin gets exposed, due either to dental caries or trauma, sensitivity starts. The dentinal tubules pass the stimulus to the pulp's odontoblastic layer, triggering the response. This mainly responds to cold.

The PDL substance has been estimated to be 70% water, which is thought to have a significant effect on the tooth's ability to withstand stress loads. The completeness and vitality of the PDL are essential for the functioning of the tooth. The PDL ranges in width from 0.15 to 0.38mm with its thinnest part located in the middle third of the root.
