Aside from regular brushing, there are some other ways to ensure your dog’s dental health – and some pretty cool reasons why they’re important. Just check out these five fascinating facts about your dog’s teeth.


Your dogs will have two sets of teeth in their lifetime. First, a set of 28 puppy teeth will force their way through the gums at about 3-4 weeks of age. These are the sharp little milk teeth that are so amazing at ripping through flesh (as any puppy owner can attest). They are very useful for your puppy’s first exploration – as young pups tend to determine what an object is by mouthing it.

Eventually, the adult teeth force their way through the gums, pushing puppy teeth out. These are the teeth that can cause serious damage should they ever be used in a bad way – they’re permanent (if taken care of!), strong, and depending on the breed, can grow quite large.

Teeth are Alive

Dog’s teeth are living tissue, just like our own set of chompers. Each tooth has several parts to it – the actual tooth is the core (called pulp) that is covered by bone, which is covered by a layer of dentine, and finally a layer of enamel. The pulp is what supplies nerves and blood vessels to the tooth to help keep them healthy.


Because teeth are alive, damage or tooth decay can lead to serious pain. That’s why dental health is such an important topic. Luckily, aside from regular brushing, there are many ways to keep your dog’s teeth healthy and strong. Water additives offer plaque-busting protection every single time your dog drinks from his bowl. Edible dental chews contain ingredients designed to clean and care for teeth, and oral sprays not only prevent plaque, but freshen breath, too!

Dogs have 42 teeth as adults!

In puppyhood, dogs only have 28 teeth (also known as “milk teeth”). But, eventually their permanent teeth come in for a total of 42 (twenty on the upper jaw, twenty-two on the bottom jaw).  By the time the adult teeth come in, your dog will have lost all of his puppy teeth. Most dogs are finished teething around six months old. You can help your puppy bring in his adult teeth by providing plenty of puppy chews to help offset the pain of bringing these new teeth in (just like we do with infants).

Each Tooth Has A Purpose

  • Incisors: These are the small teeth in your dog’s jaw. They are used for scraping flesh from bones in the wild and for picking up items (like their favorite chew toys). Your dog has 12 incisors (6 on top, 6 on bottom).
  • Canines: Also known as “fangs”, these are the teeth used to grip things your dog is trying to hold rather than eat. If you’re bitten, it’s usually the fangs that penetrate. Your dog has four canines (two on top, two on bottom).
  • Premolars: This is what your dog’s does his heavy chewing with. These teeth run up the sides of your dog’s mouth and he has four on top, four on bottom. Usually, whatever your dog chews with these teeth is what he will eventually try to ingest. Dogs usually have four on the top and bottom of both sides of their jaw just behind the canines. Nearly all dogs have a total of sixteen premolars.
  • Molars: These are located behind the premolars and they usually have two on both sides of the jaw, with three on each bottom side (for a total of ten). But, this will depend on the breed of dog and the size of his mouth. Molars are used to grind grasses and other plant material, and to break down sources of protein so your dog doesn’t choke.

Bite Force

The strength of a dog bite is between 250 and 325 PSI (pounds per square inch) whereas, the average human has a bite force of about 120-220 PSI. A domesticated dog’s bite force isn’t as strong as you may think, especially when compared to some other animal friends! In a recent experiment by National Geographic, a 2-pound Macaw had a bite force of 375 PSI (which is very close to the 400 PSI strength of a wild wolf!)

And, although they get a bad rap, the American Pit Bull terrier had one of the lowest bite forces of the large dogs tested. Of course, bite force will change according to the breed or size of dog. The records for the strongest bites of domestic dogs are actually held by Shepherds and Rottweilers.


Dogs Need Help with Teeth

Dogs rely on us to help them keep their teeth clean and working. This means getting them to the vet for checkups and regular dental exams. Regular dental exams ensure things like cavities, gum disease and broken teeth don’t jeopardize your dog’s health. Dental problems can be very painful for your dogs and in this age of new toys and indestructible chews, they occur quite often.

  1. My wife and I recently brought a new dog named Scruffles into our home and we want to know how we can take care of him. It really helped when you stated that new toys and certain types of chews can actually end up causing harsh dental problems for a dog because we were wondering what would need to be done if Scruffles decides to play with a chew toy all the time to calm himself down. I’ll be sure to remember all your tips and look for a dental care vet we can regularly take Scruffles to. Thank you!
