Dogs are toothless at birth. Their deciduous teeth are complete and functional within 2 months of birth in most breeds. Permanent teeth are complete and funtional by the end of the 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)

Canine teeth

The canine teeth are large, curved and laterally compressed. Their root is longer than their crown. They have a single root.


Molars

The molars are broader than the premolars. The large flat surface is used for grinding.

Incisors

The incisors are tricuspid in the upper jaw and bicuspid in lower jaw. They have a single root.

Premolars

The premolars are irregular and closely-spaced. They are more complex and larger caudally.

Breed Differences

Eruption times differ between breeds so it is difficult to age dogs by their teeth.
