Which statement correctly describes the function of incisors in the dental formula?

• A. Canine - tearing
• B. Incisor - cutting
• C. Premolar - crushing
• D. Molar - grinding

Answer: (B)

In the dental setup, each tooth type has a specific job. Incisors sit at the front and have a sharp incisal edge that acts like a blade, designed to cut or slice food. This cutting action is exactly how you bite into fruit or vegetables, breaking food into manageable pieces before chewing. By comparison, canines are for tearing, premolars for crushing, and molars for grinding. So describing incisors as cutting is the best fit for their role in the dental formula. For example, the front teeth cleanly slice bite-sized pieces from foods like apples.
