Teeth have three layers:
Enamel, (say ee-nam-el) is a hard protective outer layer covering the crown of the tooth. | |
Dentine, (say den-teen) is a second protective layer covering the nerve of the tooth. | |
Pulp, (also called the nerve) is the soft middle of the tooth that has a blood supply and nerve endings. |
The tooth is like an apple. An apple has an outer skin and inner flesh to protect the seeds. A tooth has an outer enamel and inner dentine to protect the pulp.
