Why Teeth and Dental Care Matter

Teeth are calcified structures in vertebrates, primarily used for chewing. Humans, like most mammals, develop two sets of teeth: milk teeth and permanent teeth. By age 18, adults typically have 32 teeth, including wisdom teeth. Teeth are categorized into incisors, canines, premolars, molars, and wisdom teeth. They are among the hardest substances in the body and are often used for identification. Despite their toughness, proper care is essential to prevent decay and infection. Regular brushing is recommended to maintain oral hygiene.
