Is enamel harder than a diamond?
No, diamond is harder than enamel.
What is dentine?
a calcareous material harder and denser than bone that comprises the bulk of a tooth
What is softer then enamel but harder than cementum?
DENTIN
What part of the tooth is harder than bone?
the enamel!
What is the function of the dentine in 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.

Dentin is a softer substance than the enamel on a tooth and is found under the enamel?
Enamel is the hard, outer material found on teeth. Underneath the enamel is dentin, which is softer and makes up most of the tooth. If a person has bad acid reflux, the enamel on their teeth comes off, and their teeth become very sensitive to temperature and certain foods.
Hardest substance in human body?
The strongest substance in the human body is DENTINE,a very hard material which resembles bone in composition but contain no haversian canals.The exposed portion of the tooth is covered with a thin layer of ENAMEL, which is even stronger than dentine. This hard part starts developing by forming a cap of predentine secreted by odonoblasts and enamel matrix formed on this predentine layer from ameoblsats.
What layer of the tooth is harder than bone?
Teeth are hard because of a crystal molecule they contain called hydroxyapatite. This molecule is part of teeth and bones and is what makes them resistant to bending or compressing. But teeth are harder than bones because the outer layer of enamel contains more hydroxyapatite than anything else in the body
What is an tooth enamel?
Hi I'm a dental hygienist so I can answer this for you!! The Enamel on your teeth is the hardest substance in your whole entire body; yes it is even harder than bone!! So the closest thing in your body to enamel is bone but it is much harder and stronger!
Which is the hardest substance present in the human body?
Hardest compont of the human body is the Enamel of the tooth (above gum line - gingivi) with approximately 95% calcium concentration The Dentin of the tooth (within enamel) has approximately 80% concentration of calcium
Dentin is a soft substance than the enamel on a tooth and is found under the enamel?
dentin is less minerelised than enamel thus it is soft
