The teeth and mouth are essential parts of the digestive and sensory systems. The mouth is the entry point for food, where the process of digestion begins. It includes the teeth, which are used to break down food into smaller pieces, making it easier to digest. The teeth consist of different types: incisors for cutting, canines for tearing, and molars for grinding. The salivary glands in the mouth produce saliva, which helps soften food and contains enzymes that start breaking down carbohydrates. The mouth also plays a role in speech, breathing, and tasting. Proper dental care is crucial for maintaining oral health and preventing issues like cavities or gum disease.
