Tooth structure 1
C cementum D dentin E enamel P pulp cavity
Enamel is hardest substance of the body and acellular.
Dentin is cellular and second hardest substance in body.
Cementum is third hardest substance in body - similar to bone.
Pulp caivty has blood vessels, nerves, lymph, and a lot of connective tissues.
