Teething begins in puppies at about 3Â½ to 4 months of age, when the primary incisors begin to be replaced by permanent incisors. By the time the average puppy reaches 6-7 months of age, all 42 adult teeth will have erupted.
When they reach 30 days of age, their deciduous or temporary (baby) teeth start to break through the gums. This is referred to as erupting.. Puppies have a total of 28 deciduous teeth by the time they reach 45 days of age. This is a good time to give puppies plenty of chew toys.
