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 funtional by the end of the 7th month.
Formula for deciduous teeth: 2 (i3/3 c1/1 p3/3)
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.
Incisors
Incisors have a single root.
Premolars
Premolars are irregular and closely-spaced. They are more complex and larger caudally.
Molars
The molars are broader than the premolars. The large flat surface is used for grinding.
Breed Differences
Eruption times differ between breeds so it is difficult to age dogs by their teeth.
