So puppies have 28 number of deciduous teeth and adult dog have 42 number of teeth.

Dentination in dogs and Dental formula

In dogs number of teeth varies in different shape and size and number. Therefore number and kinds of teeth in dog can be represented by a sort of equation which is known as dental formula. And there is to half of each job in dog is different.

And those of the upper and lower jaws are separated by a horizontal line, kinds of teeth are denoted by their initial letter i, c, pm and m representing in incissor, canines, premolars and molars respectively. Number of teeth shown in the formula multiply by 2 gives the total number of teeth in dog. in typical dog dentition includes 42 permanent teeth which are shown by the dental formula as follow

i 3/3, c 1/1, pm 4/4, m 2/3 .

To simplify further it is customary to omit the initial letter so that the same formula in dog dentination and their dental formula can be written as = 42 teeth in adult dog. It means upper jaws have 20 number of teeth and lower job have 22 number of teeth in adult dogs.

Four types of teeth in dog

There is four types of teeth in dog incissors, canine, premolar and molar As human beings.

1) incissors: Incisor present in dogs are the front teeth Born By The premaxillae in upper jaw and tip of dentaries in lower jaw. And there is 12 number of incissor present in adult dog, 6 number of Incisor in upper jaw and six number of Incisor in lower jaw.

Incissors in dogs are single rooted, monocuspid and along, curve and sharp edge like razor. And they are adapted for seizing cutting and biting and chewing, mostly in puppies they chew own food with the help of Incisor.

2) canines: in dog a single canine tooth occurs in each half of each jaw just outside the incisors. upper canines are the first teeth on maxillae. canine generally are elongated, single rooted and which conical sharp with monocuspid crown.

And there are four number of canine present in adult dog 2 in upper jow and 2 in lower jaw. it is used for holding food and puppy, piercing, tearing and offence and defence. Canine in adult dog used for puncturing and hold onto something material.

3) premolars: in adult dog canines are followed by premolar and which are followed by molar teeth. Both types are collectively known as cheek teeth. Their crown have broad surface with ridges and tubercles meant for crushing, grinding and chewing.

Pre molar teeth of dogs usually have two roots and 2 cusps and are represented in milk dentition. Actually dog is omnivorous animal they can feed meat also so last premolar in upper jaw have very sharp cusps for cracking bones and shearing tendons.

And there is 16 number of premolar teeth in adult dog 8 number of teeth present in upper jaw and 8 number of teeth present in lower jaw.

4) molar: there is heavy duty, flat shape molar teeth present in adult dog used for chewing and grinding of food. There is an unequal number of molar present in upper jaw and lower jaw in adult dog. There is total 10 teeth of molar present in adult dog 4 teeth in upper jaw and 6 teeth in lower jaw.
