Angella, my second daughter came to the kitchen yesterday asking if puppies lose their teeth. I asked her why she said our cute puppy, Montana teeth aren't complete anymore. So I carried our puppy up to confirm, and I noticed a teeth is missing. I'm scared, is my puppy sick or do puppies lose teeth?
Yes Julien, puppies lose teeth just like human. 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. So your puppy isn't sick, she is only becoming an adult.
Just like @everette has explained, at approximately 8 weeks, the puppy's teeth start falling out as the adult teeth push the milk ones out of the way.
The sequence of the teeth’s fall is: first are the incisors around 12 to 16 weeks of the puppy’s age; then the canine teeth will fall out around 16 weeks and lastly, the pre-molars around 24 weeks.
Even though the puppy teeth don't normally last long enough to have any serious problems, it’s important to get your young puppy used to a dental care regime. Gently reach into his mouth and rub his gums and teeth. This will get him used to having someone's fingers in his mouth and will make future dental care much easier.
Absolutely yes, but at the same time I will advice you visit a vet. Establishing a consistent dental care regime early on in his life is one of the best things you can do for your puppy’s health. And since his health and your happiness will invariably go hand-in-hand, you’ll be doing yourself a huge favour as well.
One thing you may not have noticed about your puppy is that the adult teeth may be coming in behind the puppy teeth and you just don’t see them yet. When the adult teeth come in they will push out the little puppy teeth.
