What is a persistent baby tooth?

Persistent baby teeth get stuck when the permanent tooth is on its way out. Usually it's the canine teeth that tend to get stuck, but it can happen with other baby teeth too. Around six months of age, all the baby teeth should have come loose and the permanent teeth should have emerged. However, it is common for this to be a little slower in smaller breeds. If the milk teeth do not come out properly, this can cause problems and damage the permanent teeth. They can also affect the development of the puppy's bite.
