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.
The hardest substance in the teeth is the enamel, which is the outer layer that protects the teeth from wear and decay. Enamel is primarily made up of minerals like hydroxyapatite, making it extremely strong and durable. However, enamel can still be damaged by acids and physical trauma.
"Enamel."
It's Dentin
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.
these are two different elements, thigh bone is "bone" and a tooth is enamel
Dentine
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.
Enamel.
Dentin is not classified as bone tissue, although it shares some similarities. It is a hard, calcified tissue that makes up the bulk of a tooth, lying beneath the enamel and surrounding the pulp. Unlike bone, dentin has a unique structure and is primarily produced by odontoblasts. Its primary function is to support the enamel and protect the inner pulp of the tooth.
Dentin is a hard tissue that makes up the bulk of the tooth structure beneath the enamel. It is sensitive to stimuli such as temperature changes and decay, and serves to protect the inner pulp of the tooth.
Enamel is stronger than hair. Enamel is the hardest substance in the human body, providing protection to the teeth from wear and decay. Hair is made of keratin, a protein that is not as hard as enamel.
