Dental formulae are used to indicate the number of each type of tooth for a given species. . Bony lesions of the jaw bone (mandible ) associated with cheek tooth loss that may indicate tooth root infection are uncommon. Management factors include drafting broken-mouthed ewes to lowground pastures where these ewes can be as productive as full-mouthed ewes provided there is an appropriate sward height and/or supplementary concentrate feeding. The dental formula for domestic sheep (Ovis aries) is 0.0.3.3/3.1.3.3, which means they have 3 upper premolare and 3 upper molars, and no upper incisors or canines.

Incisor teeth loss is readily recognised during checks for correct dentition undertaken routinely as part of the selection procedure pre-mating. Jaguars typically weigh anything between 90 and 140 kilograms. Premature loss of incisor teeth is a major problem that leads to early culling because affected sheep are unable to bite short pasture leading to malnutrition, poor production and weight loss particularly on marginal grazing and hill pastures. The dental formula for sheep and goats is as follows: 0/4 incisors, 3/3 pre-molars, 3/3 molars. Traditionally in the UK, culling for reproductive reasons follows six crops of lambs but incisor tooth loss may affect two-crop ewes on some farms representing major production and financial losses. The morphology as well as the dental formula (see Table: Dental Formulas ) of mammalian teeth, however, are variable and closely related to the animal’s alimentation. In sheep the permanent teeth are not completely erupted until 3.5 - 4 years of age. There are no recognised control measures for this sporadic condition.
