Dental Formula

2 (I3/3 C1/1 P3/3) Deciduous

2 (I3/3 C1/1 P4/4 M2/3) Permanent

Toothless at birth

Deciduous teeth complete and functional within 2 months of birth

Permanent teeth complete and funtional by the end of the 6th or 7th month

Canines

Large, curved, laterally compressed

Root longer than crown

Single root

Molars

Broader than premolars

Number of cusps similar in all breeds- usually two or three

Incisors

Tricupsid in upper jaw

Bicusped in lower jaw

Smaller rostrally

Single root

Premolars

Irregular, closely-spaced

More complex and larger caudally

Discontinuous cutting edge on crowns

Breed Differences

Eruption times differ between breeds so difficult to age dogs by teeth

Brachiocephalic dogs do not possess all cheek teeth, have fused roots and have carnasial teeth (upper P4 and lower M1)

-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]].
-===Premolars===
+'''Canines'''
-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===
+*Large, curved, laterally compressed
-The molars are broader than the premolars. The large flat surface is used for grinding. The maxillary molars have three roots each.
