Teeth
Teeth are one of the most important bony structures inside the human body. ... Ultimately, teeth are the first step of the digestive process. ... Teeth are also used in human speech. The teeth, mouth, lips and tongue are used to form words by controlling the flow of air through the mouth.1 Besides chewing food and human speech, teeth also provide the human body with a structural support to the muscles in the face that form our facial expressions. Teeth are essential to our daily lives. Our teeth are constantly being put to work; therefore it is important to eat nutritious foods that are beneficial to our teeth and to have good hygienic habits that are conducive to healthy teeth. ... 2 Permanent teeth begin to form several months before birth. ... 3 The permanent incisors and first molars begin to mineralize at, or close to the time of expected birth, while the other teeth will eventually mineralize later. When the teeth finally mineralize and form they will erupt. Even though the teeth have erupted, the roots of the teeth have not yet fully formed. When the teeth erupt, they rise from epithelial and connective tissue, which is also known as mesenchyme.
Even though humans have twenty teeth in primary sets (children about the ages of five and six have all twenty primary teeth) and adults have thirty-two teeth in a set of permanent set, each tooth has the same components. All teeth contain a vital periodontal ligament, through which roots are attached into the sockets in the alveolar bone of the jaws (maxilla and mandible). ... 4 The size and shape of each tooth in the mouth may vary depending on the function and placement of the tooth, but each is comprised of the same components in both the primary and permanent sets of teeth.
