Teeth grow fast at the early puppy stage. Because the change is so rapid, this is the most accurate time to be able to tell a dog's age. Count the type and position of your puppy's teeth to estimate their age.  Newborn puppies are born without their teeth erupted from the gums. At certain intervals teeth will erupt. The first baby teeth to appear will generally be the canine teeth at 3-4 weeks of age. At 4-5 weeks of age the two middle incisors erupt. At 4-6 weeks the first two molars erupt. At 5-6 weeks the third incisors erupt. And at 6-8 weeks of age the third molar erupts. The premolars do not appear until much later. At eight weeks and older puppies will have 28 baby teeth.  At around 4 months of age the puppy will begin to lose its baby teeth as the adult teeth will erupt. Most times, puppies swallow these teeth but occasionally the owner will find a shed baby tooth or see the gum line is bleeding where a tooth has erupted.  Just as with baby humans, puppies at this stage will love to chew on things! At 4-5 months the adult incisors, first premolar, and first molar will erupt. At 5-6 months the adult canine, premolars 2-4, and second molars erupt. Finally, at 6-7 months the adult third molar will erupt. All together there will be 42 adult teeth. In the first two years of adult life, the teeth are generally white with very little wear. By the end of the second year the white will have dulled and tartar will begin building up. This will cause yellowing on the back teeth. Eventually wear and tear and accumulation of plaque and bacteria will begin to age the teeth. This is how we estimate an adult dog’s age.  By age three, most dogs will have some signs of tooth disease: accumulation of yellow and brown tartar, reddened gums, bad breath. Of course, dogs with owners who brush their teeth daily and who take their dog to the dog dentist regularly will not have these signs of wear and tear and disease. After three to five years the yellowing will increase and be visible on all teeth. There will be noticeable tooth wear. As the dog ages, teeth will continue to show increase wear. The gums may recede from the teeth leaving roots exposed which may lead to tooth loss. The teeth staining will become more pronounced turning the yellow to brown color. From 5 to 10 years, teeth will continue to show increased wear. Signs of disease will likely appear. By 10 to 15 years, some teeth may be missing and decay will be widespread. All told, it can be difficult to determine a dog’s age by merely looking at it’s teeth. Food, habits, dental care (or lack of it) can all play a role in hastening or slowing teeth wear in all dogs.
