(A). Grinding food
(B). Mastication of food
(C). Cutting food
(D). Tearing food


Our teeth have different functions according to their location:

  • Incisors: biting and cutting food
  • Canines: piercing and tearing food
  • Posteriors: mastication and grinding food

Answer: (C). Cutting food

To memorize this, look at the image above. Scissors help us cut. Can you imagine cutting the wrapping paper you’ll use to wrap your friend’s birthday gift? Can you also associate the sharp edges of the scissor with the flat edges of the front teeth? If you can, this is now stuck in your head forever - congratulations!

Since we are all eager to learn more, let’s review some additional information that is extremely important to know for the dental hygiene board exams (NBDHE, NDHCE) related to the anatomy of the teeth. Here is a summary of the main characteristics of teeth available at StudentRDH dental hygiene board exams review course:

  • Maxillary central incisor: widest crown mesiodistally.
  • Maxillary lateral incisor: most congenitally missing tooth.
  • Maxillary canine: longest tooth in the dentition.
  • Maxillary 1st premolar: 2 roots (buccal, lingual). Other premolars have one root.
  • Mandibular 1st molar: wider mesiodistally than
  • Maxillary 1st molar: Largest tooth in the arch and in permanent dentition. 5th minor cusp (Cusp of Carabelli) present.
  • 3rd molars: usually fused roots.
