Puppies born with no teeth and like any other mammal, they have to go through a teething process. Both puppies and adult dogs have different types of teeth. 

Types Of Dog Teeth

There are four types of teeth, each one has it's own purpose:

Molars: Located behind the premolars, these are the furthest set of teeth in a dog's jaw. They are used to break down hard foods. The noise that you ear when your dog is eating kibble is produced by these teeth while smashing the food.

Premolars: These sharp-edged teeth are located between the molars and the canines, and their main function is to shred food into small pieces.

Canines: These are the long pointed teeth located behind the incisors. They are used to tear meat apart, hold objects and food or even to inflict wounds in other animals.

Did you know? Canines also help to keep the tong in place. When your puppy loses his temporary canines, you'll notice that his tong will often be hanging out of the mouth.

Incisors: Located in the front of the mouth, these small teeth are used for scrapping. When your dog gets a bone with some meat attached, you'll notice that he uses the incisors to scrape the meat of the bone (and use the molars and premolars to chew it).

How Many Teeth Do Dogs Have?

Adult dogs have 42 permanent teeth: 10 molars, 16 premolars, 4 canines, and 12 incisors, however, they are not all equally distributed between the jaws, the lower jaw has 22 teeth and the upper jaw has only 20:

One way to distinguish a puppies from adult dogs is based on how many teeth do dogs have in his mouth, since they are not the same.

How many teeth do puppies have?

Unlike adult dogs, puppies have only 28 temporary teeth: 12 premolars, 4 canines, and 12 incisors, until the permanent teeth start to erupt at 10-12 weeks oldThey don't have molars, because they don't have to crush much food at this age and they have fewer premolars than an adult dog.
