Maxillary incisors are the four front teeth located in the upper jaw, known as the maxilla. They include two central incisors and two lateral incisors. These teeth are primarily responsible for cutting and slicing food due to their sharp edges. They also play a crucial role in speech and the overall appearance of a person's smile. The maxillary incisors typically have a flat, thin shape and are larger than the corresponding mandibular incisors in the lower jaw. Each incisor has a single root and is covered by enamel, the hardest substance in the human body. Proper care of these teeth is essential for maintaining oral health.
