Just like human babies, puppies begin to develop their first set of teeth a few weeks after birth. Understanding this process can help you prepare for the teething stage and ensure your puppy’s dental health gets off to the best possible start.
Puppies are born without teeth. Their first set of teeth, known as deciduous teeth (also called milk teeth or baby teeth), begin to erupt at around 2 to 4 weeks of age. By around 6 to 8 weeks, all 28 deciduous teeth should be present. These include incisors (the small front teeth), canines (the longer pointed teeth), and premolars (the teeth behind the canines). Puppies do not develop molars at this stage; those only come in with the permanent adult teeth.
The teething process, during which the deciduous teeth fall out and adult teeth come through, typically begins at around 3 to 4 months of age. By around 6 to 7 months, most puppies will have all 42 of their permanent adult teeth. Larger breeds tend to complete teething slightly later than smaller breeds.
Common signs that a puppy is teething include:
There are several ways you can help your puppy through the teething process:
Occasionally, a deciduous tooth does not fall out when the adult tooth erupts. This is known as a retained deciduous tooth, and it is more common in small and toy breeds. A retained baby tooth can cause the adult tooth to come through in the wrong position, leading to dental crowding, bite problems, and increased tartar accumulation. If you notice a puppy tooth that does not fall out by around 6 months, it is worth mentioning to your vet, as extraction may be recommended.
