Growing Puppy Teeth

Puppies, almost without exception, are born without teeth. They have 28 temporary teeth (called puppy teeth, milk teeth or deciduous teeth) that start coming in at about three to four weeks of age. They generally fall out between 14 and 30 weeks, when they are replaced by 42 adult teeth.

Which puppy teeth fall out first?

The first to be lost are the incisors, the front six teeth on the top and bottom. Next, the long fang-like canine teeth should fall out as the permanent canines erupt. All of the 42 permanent teeth should be in place by the time a puppy is about 6 months old.
