DENTAL FORMULAS for VARIOUS SPECIES

Formulas:

I  = Incisors.
C  =  Canines.
PM  =  Premolars.
M  =  Molars.

Dog

I  =  3/3
C  =  1/1
PM  =  4/4
M  =  3/2

TOTAL  =  42 teeth for an adult dog.

To summarize, this means in the dog:

INCISORS = 3/3 

There are 3 upper incisors on both sides of the upper jaw (6 total upper incisors), and 3 lower incisors on both sides of the lower jaw (6 total lower incisors).  This equals 12 incisors total.

CANINES = 1/1

There is 1 upper canine on both sides of the upper jaw (2 total upper canines), and 1 lower canine on both sides of the lower jaw (2 total lower canines).  This equals 4 canines total.

PREMOLARS = 4/4

There are 4 upper premolars on both sides of the upper jaw (8 total upper premolars), and 4 lower premolars on both sides of the lower jaw (8 total lower premolars).  This equals 16 total.

MOLARS = 3/2

There are 3 upper molars on both sides of the upper jaw (6 total upper premolars), and 2 lower molars on both sides of the lower jaw (4 total lower molars).  This equals 10 total.

Therefore, 12 + 4 + 16 + 10  =  42 total teeth for the adult dog.

Cat

I  =  3/3
C  =  1/1
PM  =  3/2
M  =  1/1

TOTAL  =  30 teeth for an adult cat.

Rabbit (Lagomorphs)

I  =  2/1
C  =  0/0
PM  =  3/2
M  =  3/3

TOTAL  =  28 teeth for a rabbit.

FYI:  So, unlike a dog, cat or ferret, rabbits (and rodents too) have no (zero) canine teeth.  And, due to this natural “gap”, it makes it much easier to give them medications when we treat various illnesses.

Rodents (i.e. Rats, Chinchillas, Hamsters, & Mice)

I  =  1/1
C  =  0/0
PM  =  1/1
M  =  3/3

TOTAL  =  20 teeth for a rodent.

Ferret

I  =  3/3
C  =  1/1
PM  =  3/3
M  =  1/2

TOTAL  =  34 teeth for a ferret.
