Puppies have 28 temporary teeth that erupt at about three to four weeks of age.
They have 42 permanent teeth that begin to emerge at about 5 to 7 months of age.
Puppies should lose a puppy tooth before the corresponding adult tooth emerges. If a puppy tooth is still in place when an adult tooth begins to show, see your veterinarian so the dog's occlusion is not affected.
Small dog breeds are more likely to develop periodontal disease than large dogs because the teeth of small dogs are often too large for their mouths, according to veterinary dentistry experts.Puppies, like people, have a primary or deciduouse dentition. These are baby teeth, which usually are all in place by 6-8 weeks of age and which, by 16-24 weeks, are subsequently replaced by the adult teeth. In this age group we see two types of dental problems occurring: traumatic damage to the baby teeth and oral cavity, and improper eruption of the adult teeth.
