What is enamel made up of
96% mineral crystals
Tell me about enamel
Insensitive to pain, mineral crystals, the main part of it is calcium hydroxyapatite cells are made up of ameloblasts
Infomati9n about Dentine
Hollow tubules contain fibrils aka nerve endings , made up of odontoblasts and it is softer then enamel and contains calcium hydroxyapatite
Tell me about cementum
Walls to protect roots it is a calcified outer layer and it is made up of cementoblasts and attaches to the ligaments
Tell me about the pulp
Contains nerves and blood vessels the blood gives the tooth nutriance and blood enters by the apical foraman
