The root of the mandibular canine, which is fully formed by age 13, is the longest in the mandibular arch. The mandibular canines are slightly narrower than the maxillary canines but its crown is as long and sometimes is longer. The mandibular canines usually have only one root, but sometimes the root may be bifurcated, or have two roots.
Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two upper maxillary canines and the two lower mandibular ...
The anatomic root is found below the CEJ and is covered with cementum. As with the crown, dentin composes most of the root, which normally has pulp canals. Canines and most premolars, except for maxillary first premolars, usually have one root. Maxillary first premolars and mandibular molars usually have two roots. Maxillary molars usually have ...
Tooth roots can be great indicators of diets. [13] [14] In a study done on the bear tooth root area, [14] it was found that the amount of space a tooth root took up was an indicator of the bite force required from the species. For example, Panda teeth had the deepest root systems because of their bamboo diet. [14]
Supernumerary roots is a condition found in teeth when there may be a larger number of roots than expected. The most common teeth affected are mandibular (lower) canines, premolars, and molars, especially third molars. Canines and most premolars, except for maxillary (upper) first premolars, usually have one root.

The function of the mandibular tubercles is not certain, but they may also be related to jaw musculature. They are only clearly correlated with the size of the individual, though a few taxa (Brachyhyops and Cypretherium) can be diagnosed by the absence of a specific pair of mandibular tubercles. Generally, the posterior (rear) mandibular ...
