If wisdom teeth have been removed there will be 28 teeth..
What are the 4 layers of the tooth?
Human teeth are made of four types of tissue: enamel, dentin, cementum, and pulp.
These soft and hard tissue layers contain important minerals such as calcium, phosphorus, magnesium and potassium.
All of these nutrients play a vital role in forming and maintaining strong, healthy teeth that aren't sensitive to pain..
What is the correct order of the layers of tooth structure going from the outside of the tooth to the middle?
Teeth are made up of different layers — enamel, dentin, pulp, and cementum.
Enamel, which is the hardest substance in the body, is on the outside of the tooth.
The second layer is dentin, which is softer than enamel, and the deepest layer inside the tooth is pulp, which consists of nerves and blood vessels..
What is the deepest layer of the tooth?
Tooth pulp is the innermost layer of your tooth.
It contains nerves, blood vessels, specialized cells and connective tissues, which provide nutrients for your tooth.
In simple terms, dental pulp is what keeps your tooth alive.
The outer layers of your tooth — dentin and enamel — protect the pulp of your tooth..
What is the tooth covering layer?

Tooth enamel is incredibly durable.
In fact, it's the hardest substance in your body — even harder than your bones..
What layers of the tooth structure are the teeth made up of?
