Dental Fact: did you know that the enamel on your teeth is the hardest substance in your body?
Dentin supports the enamel on your teeth. It’s a yellow bone-like material that’s softer than enamel and carries some of the nerve fibres that tell you when something is going wrong inside your tooth.
The Pulp is the centre of the tooth. It’s a soft tissue that contains blood and lymph vessels, and nerves. The pulp is how the tooth receives nourishment and transmits signals to your brain.
Cementum is what covers most of the root of the tooth. It helps to attach the tooth to the bones in your jaw. A cushioning layer called the Periodontal Ligament sits between the cementum and the jawbone. It helps to connect the two.
