Know The Anatomy of Human Teeth

What are the different parts of the teeth?
  • Crown Share-upper tooth, and only a part is usually visible. The shape of the crown determines the function of teeth. For example, the front teeth are sharp and chisel-shaped for cutting, while molars have flat surfaces for grinding.
  • The gums of the teeth and gums. Without proper brushing and flossing, plaque and tartar can build on the gums, which leads to gingivitis and gum disease.
  • The root of the tooth that is embedded in the bone. Root represents about two-thirds of the teeth and holds the tooth in place.
  • Enamel, the outer layer of the tooth. Enamel is the hardest, most mineralized tissue in the body - can still be damaged by tooth decay, if not for many years.
  • Dentin-enamel of the tooth. If decay is able to progress through the enamel, it next attacks the dentin - where millions of tiny tubes lead directly to a pulp.
  • Soft Cheeses located in the center of all teeth, where the nerves and blood vessels. If decay reaches the pulp, usually feel pain.

What are the different types of teeth?
Each tooth has a specific task or function (the use of the dental arch in this section to locate and identify each type of tooth):
  • Incisors, Sharp, chisel-shaped front teeth (four upper, four lower) used for cutting food.
  • Fang, sometimes called canine teeth are in the form of points (cusps) and are used to cut food.
  • These premolars, said the two cusps on the biting surface and are sometimes called premolars. Premolars are for grinding and tearing.
  • The molars for grinding, these teeth a few nodules on the surface bite
