Question: how long does it take for a puppy's teeth to grow back?
Answer: At this age of 8 months, the puppy should have 42 teeth -12 incisors, 4 canines, 16 premolars and 10 molars. Puppies have 28 temporary teeth (called puppy teeth or milk teeth) that start coming in at about four weeks of age. They generally fall out between 14 and 30 weeks, when they are replaced by 42 adult teeth.
