A human has a mouth whose primary role is communication and food intake. The mouth contains the teeth, tongue, and gums. A normal adult has a total of 32 teeth in the mouth. The teeth are separate and play different roles in speech and eating. We are going to discuss the teeth and their parts.
Parts of the teeth
The teeth are the hardest parts of the body. They are responsible for chewing as well as speech. The teeth have parts like enamel, dentin, pulp, cementum, and the periodontal ligament that aid their functionality. The enamel is the hard white outer part of the tooth made of calcium phosphate material. The dentin is the layer under the enamel described as a hard tissue that contains vessels and nerves. When the enamel is hurt, the dentin can feel the heat and cold, which are usually painful. The pulp is the tissue inside the tooth. It is where the nerves and blood vessels pass. The cementum is a tissue in the jaw that holds the teeth firmly to the gums and jawbone. Periodontal ligament assists in firmly maintaining the teeth in the jaw.
The teeth are grouped into incisors, canines, premolars, and molars. Each of the grouped sets of teeth plays a separate role. The incisors are the teeth in the front middle. There are four incisors in the upper and lower jaw. The canines are four, two on each jaw, and follow the incisors, one on each end. The premolars are eight in number and follow the canines. The molars are the teeth at the rear side of the mouth. They are flat and are good for grinding. The teeth at the end are the wisdom teeth and erupt at the older age of eighteen years.
The teeth are susceptible to some diseases due to poor health. The diseases include cavities, periodontitis, gingivitis, plaque, and tartar. These diseases are caused by the lack of regular brushing and flossing. Regular visits to our dentist are recommended for excellent dental health. Visit us for more information on the teeth anatomy.
