Your puppy’s first baby teeth, also called deciduous teeth, come in between six and eight weeks of age.
Since this happens before you bring him home, you won’t have to deal with this. However, those baby teeth only last a few months before his adult teeth break through the gums. This can cause as many problems for your puppy as it does for human children when they’re teething. It’s a tough time for both the puppy and her owners.
Puppies will begin losing baby teeth and growing in adult teeth at an individual rate. However, most puppies begin loosing their incisors (those tiny teeth at the front of the mouth) during the puppy’s third month, often towards the end of the third month. These lost incisors will let you know teething has started.
The teething then moves from front to back. The canine teeth (the fangs) usually fall out next, followed by the premolars and then molars. However, it’s not unusual for the fangs to remain as the premolars fall out. Between six to eight months, your puppy should have all 42 adult teeth.
Retained Baby Teeth
When your puppy goes to the veterinarian’s clinic for vaccinations, the veterinarian will check your puppy’s mouth to see how teething is progressing. However, check your puppy’s mouth regularly in between these appointments and if you see a retained baby tooth with an adult tooth growing in beside it, give your vet a call to see if she wants to see your puppy right away. A retained baby tooth can cause damage to the permanent tooth. If the baby tooth isn’t pulled in a timely manner, the adult tooth could grow in crooked, causing it to be in an incorrect position in the puppy’s mouth. This could cause him difficulty eating, pain in his mouth, and a variety of other problems.
