Cattle dental formula

  • Cattle have both temporary (deciduous) and permanent dentition.
  • Maxillary front teeth are absent and the premaxilla is attached by a thick horny epithelium covering a layer of fibrous connective tissue which comprises the "dental pad".
  • I = Incisor.
  • C = Canine.
  • P = Premolar.
  • M = Molar.
  • There are 20 deciduous teeth with a dental formula of:
    • 0 - 0 - 3 - 0.
    • I-  C-  P-  M-   x 2 = 20.
    • 3 - 1 - 3 - 3.
  • There are 32 permanent teeth, the 3 pairs of premolars in each jaw are supplemented by 3 pairs of molars in both maxilla and mandible. Dental formula of:
    • 0 - 0 - 3 - 3.
    • I-  C-  P-  M-   x 2 = 32.
    • 3 - 1 - 3 - 3.
  • The 3 incisors and 1 canine that comprise the front teeth are all spatulate (broad and rounded end) and arranged in a broad linear arch.
  • Some people refer to the canine tooth as the 4th or corner incisor.
  • The fixation of the teeth within each socket allows some dorsoventral movement within "alveoli".
  • There is a large diastema between front and cheek teeth.
  • Cheek teeth increase in size caudally, with the mandibular premolars and molars being narrower than the maxillary.
