acrodonty

Acrodonty refers to a dental condition where teeth are fused to the crest of the jawbone, lacking a distinct socket. In this arrangement, the teeth stand on top of the alveolar bone rather than being embedded within it. This type of tooth attachment is common in many species of fish, amphibians, and reptiles. For example, acrodont dentition is found in groups like teleost fish and lizards. Unlike pleurodonty, where teeth are attached to the inner side of the jawbone, or thecodonty, where teeth are set in deep sockets, acrodont teeth are less firmly anchored. This can make them more prone to wear and loss. However, the specific function and adaptation of acrodonty vary significantly across different animal groups, often correlating with their diet and feeding mechanisms. In some cases, the teeth are continuously replaced throughout the animal's life, compensating for wear and tear. The term itself derives from Greek words "akros" meaning summit or tip, and "odous" meaning tooth, accurately describing the position of the teeth.
