    Retained deciduous (baby) teeth occur frequently in puppies, especially those of toy breeds. The canine tooth (fang) is the tooth most commonly retained as the permanent tooth grows in alongside it. If it remains, it may affect the position of the permanent tooth. Your veterinarian may elect to surgically remove the retained tooth, especially if it's still there at 6 months of age. Many veterinarians radiograph the area before removing a tooth to make sure a permanent tooth is present to take its place.
