Detailed explanation-1: -Heterodont dentition involves four types of teeth – incisors, canines, premolars and molars. There are three dentition types based on attachment of teeth. Thecodont is the condition when teeth are attached to sockets on the jaw bone. Acrodont dentition refers to the condition where teeth are fused to the jaw bone.

Detailed explanation-2: -In Class Mammalia, teeth are of different types (heterodont) and are embedded in the socket of the jaw (thecodont). These are developed twice during the lifetime of the animal (diphyodont), i.e., milk and permanent teeth.

Detailed explanation-3: -Thecodont is a type of dentition in which the teeth are embedded in the deep sockets of the jaw bone. Examples include living crocodilians and mammals.

Detailed explanation-4: -Thecodont teeth are present in crocodiles, mammals, and dinosaurs. It is a type of tooth present in the animals where the root of the teeth is firmly attached in the socket of the jawbone, an archosaurian characteristic that was inherited by the dinosaurs. This attachment is the strongest in the vertebrates.

Detailed explanation-5: -Thecodont teeth or thecodont dentition describes the morphology of teeth. These types of teeth have well developed roots. Thecodont teeth are deeply embedded in the sockets of the jaw bone. These are present in mammals, certain reptiles such as crocodiles and in distinct animals such as dinosaurs.
