A tooth is a hard, white structure found in the mouths of many animals, including humans. It helps us chew food, making it easier to digest. Each tooth has a specific shape and function, such as cutting, tearing, or grinding. Our teeth are made of enamel, dentin, and pulp, and they play a crucial role in our overall health. Taking care of our teeth is important to prevent problems like cavities and gum disease. Regular brushing with a toothbrush and using toothpaste can help keep them clean. Visiting a dentist for check-ups ensures that our teeth stay healthy and strong throughout our lives.
