Understanding the Puppy Teething Process

Aside from protecting the sofa legs from your puppy’s incessant chewing, there’s not a whole lot to do while your new pet is going through the teething process. Knowing the details of teething is a good idea, though. That way, you know what your puppy is going through and when, and you can let your vet know right away if something seems amiss.

Newborn Puppies

Just like human babies, puppies are born with no teeth. They don’t need them at this stage, after all—your puppy will suckle milk from their mother if the mother is around, or they’ll need to be hand-fed from a bottle if the mother isn’t available.

2-3 Weeks of Age

Around two or three weeks of age, your puppy’s first baby teeth will start coming out of the gums. The smaller front teeth, called the incisors, are usually the first to appear. The canine teeth will follow—these are the four long fangs. Your puppy’s premolars are the last to appear, and they come in behind the canines near the back of the mouth. When it’s all said and done, your puppy will have 28 baby teeth, which are known medically as the deciduous teeth and are often referred to as the “milk teeth.”

6 Weeks of Age

By the time your puppy is about six weeks old, all 28 baby teeth will probably have come in. Around this time, your pup will be in the process of getting weaned off of the mother’s milk or formula, and they’ll begin eating solid puppy food.

3-4 Months of Age

Around the 12- to 16-week mark, your puppy’s baby teeth will start falling out. The adult teeth come in and simply push the deciduous teeth out of the way, so you may occasionally see a baby tooth on the floor or by your puppy’s water or food bowls. Most often, though, your pup simply swallows the baby teeth as they come out, which is perfectly normal.

6 Months and Older

By the time your dog is six months old, all 28 baby teeth will likely be gone, replaced by 42 adult teeth. Your puppy will now have molars in addition to premolars, which are the largest teeth at the back of the mouth that help with chewing and mashing food.

Our Advice on Understanding the Puppy Teething Process in 2025

How often should a puppy’s teeth and gums be examined by a veterinarian during the teething stage?

During the teething stage, a puppy’s teeth and gums should be examined by a veterinarian at least once a month. Regular check-ups are crucial to monitor the development and ensure there are no complications such as retained baby teeth, misalignment, or gum infections. These visits also allow the veterinarian to provide guidance on managing teething discomfort and maintaining oral hygiene. Early and consistent dental care helps establish a healthy foundation for the puppy’s adult teeth and prevents potential dental issues in the future.

Can the teething process affect a puppy’s overall health or behavior, such as appetite, sleep patterns, or socialization?

Yes, the teething process can affect a puppy’s overall health and behavior. During teething, puppies may experience sore gums, leading to decreased appetite and changes in eating habits. Discomfort from emerging teeth can disrupt sleep patterns, making puppies more restless or irritable. Additionally, the need to chew increases significantly, which can impact behavior and socialization. Puppies may become more focused on chewing objects, which can sometimes result in destructive behavior. Monitoring and providing appropriate chew toys can help alleviate discomfort and support healthy development and behavior during this stage.

Are there any long-term consequences of dental issues that arise during the puppy teething stage?

Yes, dental issues during the puppy teething stage can have long-term consequences. Problems such as retained baby teeth, misalignment, or gum infections can lead to chronic pain, difficulty eating, and even behavioral issues due to discomfort. Poor dental alignment can cause abnormal wear on teeth and increase the risk of periodontal disease, which can affect overall health. Early detection and treatment of dental issues by a veterinarian are crucial to prevent these long-term consequences and ensure a healthy adult dentition for the puppy.

What is the role of genetics in a puppy’s dental development and teething process?

Genetics play a significant role in a puppy’s dental development and teething process. Genetic factors determine the timing of tooth eruption, the alignment of teeth, and the overall dental structure. Certain breeds may be predisposed to specific dental issues, such as overcrowding, misalignment, or retained baby teeth. Hereditary conditions can also influence the risk of periodontal disease and other oral health problems. Understanding a puppy’s genetic background helps veterinarians anticipate potential dental issues and tailor preventive care to ensure optimal dental health as the puppy matures.

How can puppy owners establish good dental hygiene habits and routines during the teething stage?

Puppy owners can establish good dental hygiene habits during the teething stage by introducing regular tooth brushing with a pet-safe toothpaste. Start by gently massaging the puppy’s gums to get them accustomed to oral care. Provide appropriate chew toys to help alleviate teething discomfort and promote healthy chewing behavior. Regularly inspect the puppy’s mouth for signs of dental issues, such as retained baby teeth or gum inflammation. Establish a routine of professional dental check-ups with the veterinarian to monitor dental development and address any concerns early, ensuring lifelong dental health.
