Dogs are toothless at birth. The '''deciduous''' teeth are complete and functional within 2 months of birth in most breeds. '''Permanent''' teeth are complete and functional by the end of the 7th month.

===Incisors===
 +
Dogs have six incisors in the maxilla and six in the mandible. Incisors have a single [[Tooth - Anatomy & Physiology#Root|root]].
   −
===Canines===
+
===Canine Teeth===
 +
The canine teeth are large, curved and laterally compressed. Their [[Tooth - Anatomy & Physiology#Root|root]] is longer than their [[Tooth - Anatomy & Physiology#Crown|crown]]. They have a single [[Tooth - Anatomy & Physiology#Root|root]].
   −
The canines are large, curved and laterally compressed. Their [[Root - Anatomy & Physiology|root]] is longer than their [[Enamel Organ#Crown|crown]]. They have a single [[Root - Anatomy & Physiology|root]].
+
===Premolars===
−
 
+
Premolars are irregular and closely-spaced. They are more complex and larger caudally. The first maxillary premolar has a single root, the second and third maxillary premolar have two roots and the fourth maxillary premolar (carnasial tooth) has three roots.

===Molars===
 
===Molars===
 +
The molars are broader than the premolars. The large flat surface is used for grinding. The maxillary molars have three roots each.
   −
The molars are broader than the premolars. The number of cusps is similar in all breeds, usually two or three.
+
==Breed Differences==
−
 
  −
===Incisors===
     −
The incisors are '''tricuspid''' in the upper jaw and '''bicuspid''' in lower jaw. They are smaller rostrally and have a single [[Root - Anatomy & Physiology|root]].
+
Eruption times differ between breeds so it is difficult to age dogs by their teeth.  
   −
===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]].

==Breed Differences==
     −
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 [[Root - Anatomy & Physiology|roots]]''' and '''carnasial teeth''' (upper P4 and lower M1).
