As a pet parent, it is important to keep an eye on your dog's teeth because oral health issues are fairly common in dogs over the age of three. Our Pico Rivera vets are here to give you the inside scoop about the number of teeth your dog should have and why they might be losing teeth.
How Many Teeth Do Dogs Have?
The number of teeth in a dog’s mouth will change as they grow from puppies into adult dogs.
Puppy Teeth
Puppies are born toothless, and their puppy teeth do not appear until they are 3 to 4 weeks old. By 3-5 months of age, they should have all 28 puppy teeth, including incisors, canines, and premolars.
Adult Teeth
The age of eruption of adult teeth in dogs is between 3-7 months of age. Adult dogs should have 42 permanent teeth, as compared to humans who have 32 teeth.
Their upper jaw has 20 teeth, while their lower jaw has 22 teeth.
Types of Dog Teeth
Each of a dog's teeth—incisor, canine, premolar, and molar—serves a specific function. Here is an explanation of what each type of tooth does and where they are located in your dog's mouth:
Incisors
What is the most visible part of your dog's smile? The teeth's incisors! These are the small teeth directly in front of the upper and lower jaws. They use them to scrape at meat and groom their coats.
Canines
The canines, or "fangs," are located behind the incisors. They are a pair of long, pointed, and extremely sharp teeth on both sides. Canine teeth tear into meat and grip objects. Dogs can also show these teeth if they feel threatened or defensive, which is why understanding dog body language is critical.
Pre-Molars
On either side of a dog's jaw on both the top and bottom are wide pre-molars, or carnassials. A lot of shredding and chewing is done with these teeth, which is why they're relatively sharp.
Molars
At the very back of a dog's mouth, above and below, are flat molars. He uses these to crunch on hard things, such as treats or kibble.
Why Dogs Lose Teeth
Aside from the transition from puppy teeth to adult teeth, it is not normal for a dog to lose teeth. If you notice that your dog is losing their adult teeth, you should contact your vet and schedule a dental appointment.
Here are the most common reasons for a dog to lose their adult teeth.
- Periodontal Disease - The most common reason for a dog to lose teeth is because of advanced dental disease in their mouth. Without proper dental care—like brushing and veterinary dental cleanings—periodontal disease can lead to diseased gums and decaying teeth.
- Trauma - Your dog's teeth can be lost due to trauma, whether it is caused by chewing something or another injury to its mouth. Some of the most common items that can lead to tooth fractures or loss are made of dense mineral or bone material. To protect your dog's teeth, avoid giving your dog things like beef or pork bones, as these can be too hard and often result in fractures and tooth damage.
- Tooth Decay - Dog teeth decay and wear and tear at a much faster rate than human teeth. They use their teeth to pick up, carry, and chew objects. Furthermore, slobbery toys, hair, dirt, feces, and food all pass through a dog's mouth. All of this can have an impact on their dental health. Some dogs (particularly small breed dogs and Greyhounds) develop tooth decay at an alarming rate, necessitating the extraction of numerous teeth by a veterinarian over the course of their lives.
How To Prevent Dogs From Losing Their Teeth
More than 80% of dogs will have some form of periodontal disease, including gingivitis, by the age of three. This means that your dog's teeth should be brushed on a regular basis to avoid dental disease. Giving your dog dental chews is a good idea, and you should take him to the vet for thorough cleaning on a regular basis. If you notice your dog having difficulty chewing or if you have other concerns about their teeth or mouth (including bad breath! ), consult your veterinarian to determine the best course of action to keep those chompers healthy.
If you notice that your dog is losing teeth, has loose or wiggly teeth, or has progressively worsening breath, please set up a consultation with a veterinarian as soon as possible. Even if it seems like they just lost one tooth, it is likely that your pet has more diseased teeth in their mouth causing discomfort that would benefit from removal. Don’t wait until your pet is not eating to get a dental consult with your veterinarian. Use your pet’s annual exam as an opportunity to discuss your dog’s teeth and overall dental health before there is a problem.
