What is the hardness of tooth enamel on the mohs scale?
Tooth enamel has a Mohs hardness of around 5 on the Mohs scale. It is harder than most other parts of the human body, but can still be worn down by acidic foods and poor dental hygiene practices.
Do teeth have nerve endings and how do they contribute to tooth sensitivity?
Yes, teeth have nerve endings that are located in the pulp of the tooth. When the protective enamel layer is worn down or damaged, these nerve endings can be exposed to external stimuli such as hot or cold temperatures, causing tooth sensitivity.
Why is acid bad for your teeth?
Acid can erode the enamel on your teeth, which is the protective outer layer. Once the enamel is worn down, teeth become more vulnerable to decay and sensitivity. It can also lead to cavities and tooth sensitivity.

What is the difference between a tooth and a bone?
Enamel is developed during infancy and adolescence only. Once the tooth has erupted into the mouth, no more enamel is created. Enamel has no innervation and no blood supply. In short, it is not living tissue, and cannot be healed if broken by trauma or disease (tooth decay). In contrast, bone tissue has blood supply and innervation. It continues to replace it's worn out cells throughout life, and it is capable of healing if damaged through injury or disease.
Why Do Our Teeth Discolor?
As you age, the outer layer of enamel on your teeth gets worn away exposing the yellow dentin. Your tooth dentin also grows as you age, which decreases the size of the pulp. The translucency of the tooth reduces, making it look darker. Genetics: Thicker and whiter enamel runs in some families.
What are the three types of Dentin in teeth?
The structure of a tooth includes three major divisions: the tooth root, the dentin (pulp) and the enamel. The tooth root is connected to the blood supply, which carries oxygen and nutrients to the cell, including calcium to replace worn enamel. The dentin is the living interior, which maintains the nerve tissue and enamel-producing cells. The enamel is the hard outer surface. It consists of hard, hollow tubules packed tightly together like bundles of drinking straws. The enamel that wears away from chewing can be replaced by new material.
What are sperm whales teeth made of?
A sperm whale possesses teeth with cementum cells overlying dentin cells. Unlike human teeth (which are comprised mostly of enamel on the tooth portion outside of the gum) sperm whale teeth have cementum outside the gum. Only in larger whales does some enamel show where the cementum has been worn away on the tip of the tooth, revealing the underlying enamel.
