What is dentine?
Dentine is a mineralized tissue that makes up the majority of a tooth's structure. It lies beneath the enamel covering of the tooth and is softer than enamel but harder than bone. Dentine plays a crucial role in supporting and protecting the inner pulp of the tooth.
Is enamel harder than a diamond?
No, diamonds are harder than enamel. Diamonds rank as the hardest natural material known, scoring 10 on the Mohs Scale of Hardness, while enamel, the outer layer of teeth, ranges from 5 to 7 on the scale.
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.

What is softer then enamel but harder than cementum?
Dentin is a tissue that is softer than enamel but harder than cementum. It makes up the majority of a tooth's structure and provides support and protection to the inner pulp tissue.
Dentin is a soft substance than the enamel on a tooth and is found under the enamel?
Dentin is a hard tissue that lies beneath the enamel in a tooth, providing support and protection to the inner structures. It is not as hard as enamel but harder than pulp, the innermost part of the tooth.
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
The enamel on your teeth is harder than any bone in your body?
Yes, the enamel on your teeth is indeed harder than any bone in your body. Enamel, which is primarily composed of hydroxyapatite, has a high mineral content that gives it exceptional hardness and resilience, making it well-suited to withstand the forces of chewing. While bones are strong and can withstand various stresses, their structure allows for some flexibility, which makes them less hard than enamel. This hardness is crucial for enamel's role in protecting the teeth from decay and wear.
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
