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!
That is correct. The exterior of any large bone is harder than the interior marrow.
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.
The hardest substance in the human body is tooth enamel. It is even harder than bone and serves as the outer protective layer of our teeth.
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
No. It does not have the amount of calcium as bone.
Tooth enamel is the outermost layer of the tooth, protecting it from decay and damage. It is the hardest substance in the human body, made up of minerals like calcium and phosphate. Maintaining good oral hygiene practices can help protect and strengthen tooth enamel.
Enamel, which covers the outer layer of teeth, is the hardest substance in the human body. It is even harder than bone.
The hardest bone in your body is your thigh bone. Its stronger than concrete!
Epidermis - 1st layer - outermost thinner layer covering of our body and protection Dermis - 2nd layer - Tiny blood cells and capillaries harder than the first layer. It gives skin complexion Subcutaneous tissue - 3rd layer - Most hardest layer - above the bone - Protection for bone
Because bone is much harder than cartilage
No, the hardest bone in the body is the femur (thigh bone) which is harder than concrete. :)
