If there are 206 bones in the human body, are teeth considered to be bones?

Is a tooth a bone or just a form of a bone?

If there are 206 bones in the human body, are teeth considered to be bones?
neither, it is a different type of tissue completely, both in structure and embryological origin.
Reply:i agree with the first person!
Reply:yep, troy is right - i think thats the second time this week he%26#039;s written a better answer than i could.


did you know the only part of you body that cannot heal its self is a tooth?
Reply:no it%26#039;s not a bone it%26#039;s a tooth
Reply:Although the tooth is often considered a %26#039;bone%26#039; fact is that is really isn%26#039;t a true part of the osteo family.





It has its own characteristics such as tooth enamel, etc.
Reply:The tooth is anchored in the bone and the bone forms part of the jaw.


(Bone - alveolar bone forms the tooth socket and provides it with support)








There are 206 bones in the human skeleton, not including teeth and sesamoid bones (small bones found within cartilage):


• 80 axial bones, which include the head, facial, hyoid, auditory, trunk, ribs, and sternum.


• 126 appendicular bones, which include arms, shoulders, wrists, hands, legs, hips, ankles, and feet.
Reply:No, teeth are made of a composition of mineral salts, calcium, and phosphorus. The layer of the tooth that you brush is called the enamel, while the majority of the tooth material itself is called dentine. Bones on the other hand are made of calcified tissue, except during the first few weeks of of pregnancy where your bones are composed of cartilage, then after a few weeks a process called ossification takes place where your cartilagenous tissue is slowly replaced by calcium phosphate. This process of ossification where your bones become more and more calcified is completed around the age of 25. Teeth like bones are composed of calcium, but bones have far more calcium than teeth do. Hope that answers your question.
