The main components which form the enamel organ are:
The main components which form the enamel organ are:
*'''Outer epithelium'''
*'''Outer epithelium'''
'''Secondary dentine''' is produced throughout life and increases with rate of repair. It is darker in colour than '''primary dentine'''.

===Cementum===
'''Cementum''' is synthesised by '''[[Cementoblasts - Anatomy & Physiology|cementoblasts]]'''. It is calcified tissue and lacks regular organisation. Collagen fibres extend from the cementum into the '''[[Periodontal ligament - Anatomy & Physiology|periodontal ligament]]''' to fasten the tooth in its socket. '''Cementum''' is relatively immune to pressure erosion, therefore the tooth can be be romedelled in its socket.
