what is teeth

Teeth are hard, calcified structures found in the mouths of many vertebrates. In humans, they play a crucial role in the digestive system by breaking down food through cutting, crushing, and grinding before swallowing. Most adults have 32 permanent teeth, which include incisors, canines, premolars, and molars. Each type of tooth has a specific function, such as biting, chewing, and grinding up food. The enamel, which is the hardest, white outer part of the tooth, is mostly made of calcium phosphate, a rock-hard mineral. Teeth also play an important role in speech and are an essential part of a persons smile, contributing to their confidence and social interaction. Its important to care for teeth by visiting the dentist regularly and practicing good oral hygiene at home to maintain their health and functionality.
