Tooth refers to the hard, calcified structure embedded in the jaws of vertebrates, primarily used for chewing and grinding food. It is composed of enamel, dentin, and pulp, and is covered by gum tissue. Teeth play a vital role in the digestive process by breaking down and masticating food before it enters the stomach.
In humans, there are two sets of teeth that develop over a lifetime: the primary (baby) teeth and the permanent (adult) teeth. The primary teeth begin to erupt around six months of age and are eventually replaced by the permanent teeth, which emerge between the ages of six and twelve. The human adult dentition typically consists of 32 teeth, including incisors, canines, premolars, and molars.
Each tooth has a specific function based on its location and shape. Incisors are used for cutting and biting, canines are helpful for tearing into food, premolars assist in chewing and grinding, while molars are responsible for crushing and grinding tougher foods. The shape and arrangement of teeth in different animals vary according to their diet and evolutionary adaptations.
Maintaining good oral hygiene is essential for healthy teeth. Regular brushing, flossing, and dental check-ups help prevent tooth decay, gum disease, and other dental issues. Poor oral health can lead to tooth loss and impact overall well-being. Dentists specialize in the diagnosis, treatment, and prevention of dental disorders, ensuring the longevity and functionality of teeth.
