==Resumen==
Dogs are toothless at birth. Their '''deciduous''' teeth are complete and functional within 2 months of birth. '''Permanent''' teeth are complete and funtional by the end of the 6th or 7th month.
The formula for '''deciduous''' teeth: 2 (I3/3 C1/1 P3/3)
The formula for '''permanent''' teeth: 2 (I3/3 C1/1 P4/4 M2/3)
===Caninos===
The canines are large, curved and laterally compressed. Their [[Enamel Organ#Root|root]] is longer than their [[Enamel Organ#Crown|crown]]. They have a single [[Enamel Organ#Root|root]].

===Molars===
The molars are broader than the premolars. The number of cusps is similar in all breeds, usually two or three.
===Incisors===
The incisors are '''tricuspid''' in the upper jaw and '''bicuspid''' in lower jaw. They are smaller rostrally and have a single [[Enamel Organ#Root|root]].
===Premolars===
The premolars are irregular and closely-spaced. They are more complex and larger caudally. They have a discontinuous cutting edge on [[Enamel Organ#Crown|crowns]].
==Diferencias Entre Razas==
Eruption times differ between breeds so it is difficult to age dogs by their teeth. '''Brachiocephalic''' dogs do not possess all of the cheek teeth. They have '''fused [[Enamel Organ#Root|roots]]''' and '''carnasial teeth''' (upper P4 and lower M1).
