Tooth

A tooth is a dense fibrous tissue inside the body (as opposed to the lining of the mouth), which is formed from the soft tissues surrounding it. This is part of the animal's digestive tract and the plant juice enclosed in it. It consists of the root system and dentition, which are collectively called the jaws. Teeth are part of the skeleton and are located in the oral cavity and are intended for eating food for the purpose of grinding or chewing it. They are necessary for grinding plant mass and consist of organic matter - dentin.
