Dentine contains a larger protein content in addition to hydroxyapatite. Dentinal canaliculi (so-called tubules) can also be found in dentine. When dentine is exposed in the oral cavity, this can lead to pain-sensitive teeth.
In summary, it can be said that teeth are hierarchical biocomposites with special properties:
- Fracture strength
- Self-repair mechanism by means of remineralisation from saliva
