Human teeth have no way to repair the damage done to them. However, human teeth, with the help of human saliva, can remineralize themselves to combat demineralization caused by food and drink.
The hard surface of the tooth is made of enamel which is the hardest tissue in the human body. Tooth enamel has no living cells so unlike a broken or fractured bone the body has no way to repair chipped/cracked enamel.
It is called the enamel. It's the most external layer of a tooth and the hardest substance in the body.
TEETH are the only part of the body that can't repair itself
Enamel is called the dentine part of the tooth
It is one of the 4 components of the mammalian tooth and is to be found just beneath the hard enamel outer layer or in ridges between ridges of hard enamel. Being softer than the enamel, in herbivores (like the elephant) the dentine wears away faster ensuring that the roughness of the tooth surface is maintained as the tooth itself wears away. In omnivores and carnivores, it mechanically supports the enamel surface and protects the tooth pulp and nerves.

Tooth enamel.
yes
Calcium is a metal element present in tooth enamel.
Tooth paste is a flavoured mild abrasive. It removes stains and polishes the enamel. The brush itself actually cleans food particles off the teeth,not the paste.
Eroding away of tooth enamel
it is called enamel. so the answer is true It is called enamel
