It was theorized that positive selection for shovel-shaped incisors over the spatulate incisors is more commonly found within cultures that used their teeth as tools due to a greater structural strength in increased shovel-shaped incisors. [2] In some instances, incisors can present a more pronounced version of this called double shovel-shaped.
Horse teeth often wear in specific patterns, based on the way the horse eats its food, and these patterns are often used to conjecture on the age of the horse after it has developed a full mouth. As with aging through observing tooth eruption, this can be imprecise, and may be affected by diet, natural abnormalities, and vices such as cribbing.

The unusual saw-like tooth whorl and the lack of wear on the teeth of Helicoprion implies a diet of soft-bodied prey, as hard-shelled prey would simply slip out of the mouth. Due to the narrow nature of the jaw, suction feeding is unlikely to have been effective, and Helicoprion is thought to have been a bite feeder .
The specialised teeth—incisors, canines, premolars, and molars—are found in the same order in every mammal. [6] In many mammals, the infants have a set of teeth that fall out and are replaced by adult teeth. These are called deciduous teeth, primary teeth, baby teeth or milk teeth.
A saw set is a tool or part of the tool kit for tuning saw blades. It adjusts the set , or distance the saw tooth is bent away from the saw blade. The magnitude of set determines the cut width and prevents the blade of the saw from binding in the wood.
A caudal hook is characterized by the posterior molar developing a growth which overhangs and “hooks” around the adjacent tooth. This diagram depicts a caudal hook on the lower last molar, however the upper last molar can also develop a caudal hook.
