Dentitions refer to the arrangement, type, and number of teeth found in the jaw bones of animals. Synonyms for the term dentitions include dental formula, tooth arrangement, tooth structure, and tooth morphology. A specific type of dentition can also be referred to as a dentition pattern, such as the deciduous dentition of young animals or the permanent dentition of adult animals. Dentitions can vary greatly between species, with some animals having specialized teeth for specific purposes, such as the sharp canines of carnivorous animals or the flat molars of herbivores. Understanding the dentition of an animal can provide important information about their feeding habits and evolution.
