Structure of mammalian tooth, types of teeth in vertebrates, dental formula in mammals
Understand the Problem
The question is inquiring about the anatomy of mammalian teeth, the different types of teeth found in vertebrates, and the dental formula specific to mammals. This involves understanding tooth structure, function, and classification across various vertebrates.
Answer
Mammalian teeth include incisors, canines, premolars, and molars. Eutheria have 3 molar pairs and 4 premolars per jaw; Metatheria have 4 molar pairs and 3-2 premolars.
Mammalian teeth are heterodont, consisting of incisors, canines, premolars, and molars. The dental formula for mammals varies by group: Eutheria typically have three pairs of molars and four premolars per jaw, while Metatheria have four pairs of molars and three or two premolars.

More Information
Mammalian teeth are specialized for different functions — cutting, tearing, grinding, etc. — reflecting a diverse range of diets among different species.
Tips
A common mistake is confusing the dental formulas of different mammalian groups, which differ significantly in the number of specific teeth types.
