![]() ![]() Cementum covers the root, and the alveolar bone is the bone that supports the teeth. The periodontal ligament is the connective tissue that attaches the tooth to the bone. The gingiva is the soft tissue that surrounds the teeth and covers the jawbone. It consists of four parts: the gingiva (gums), the periodontal ligament, cementum, and alveolar bone. The periodontium is the supporting structure of the tooth. The Periodontium: The Support System of the Tooth ![]() The pulp in the root is responsible for nourishing the tooth. The root also has three layers: cementum, dentin, and pulp. It is covered with cementum, a layer that attaches the tooth to the bone. The root is the part of the tooth that is embedded in the jawbone. Pulp is the innermost layer, and it contains nerves and blood vessels. Dentin is the layer beneath enamel, and it is yellowish in color. Enamel is the outermost layer, and it is white in color. The crown consists of three layers: enamel, dentin, and pulp. Enamel protects the tooth from decay and erosion caused by bacteria and acid. The crown is the visible part of the tooth, and it is covered with enamel, the hardest substance in the human body. By the end of this article, you will have a comprehensive understanding of tooth anatomy. In this article, we will delve deep into the structure of teeth, their functions, and how they contribute to overall oral health. We, as dental professionals, believe that understanding the anatomy of teeth is crucial in maintaining good oral health. Check out the worksheet below for more practice on how to label a tool. The terms used to label a teeth diagram are familiar words you see in other contexts. The roots are held in place in the gum through what is called cement. They stick our teeth right into the bone passing through the gum. Think about the function plant roots play it is the same function the roots of our teeth play. The teeth are actually stuck to this section by what is called the root. The gum itself is the red or dark part to which our teeth stick. The neck is the section that is in contact with the gum. The sensitivity of our teeth is accounted for by the presence of these sensory nerves underneath it. The pulp cavity contains the root canal within which are blood vessels and nerves. Directly underneath the enamel is the dentine and underneath the dentin is the pulp cavity. ![]() It is what we brush with tooth paste to keep clean and void of bacteria. The crown is made up of the enamel the white hard part that is visible from the outside. Each part is further divided into other distinct units with each one displaying a unique characteristic. The tooth is made up of three distinct parts as follows: the crown, the neck and the root. The ability of the teeth to chew hard food particles into smaller pieces tells of an organ that is built tough to resist breaking off. When we ingest food in the mouth, our teeth help us to chew the food into tiny particles that can be further digested when they get into the stomach. There is a worksheet below on a tooth diagram to label.ĭigestion begins in the mouth. This is a great free teaching resource for parents and teachers. Students can freely practice and home or in school. This quiz is interactive and feedback in instant. Each tooth has different parts and each part plays a particular role. In this quiz on tooth anatomy, students will learn how to draw and label a tooth. This is a bilogy quiz online for children in 2nd, 3rd, 4th, 5th and 6th grades.
