How many teeth do dogs have?
The actual number of teeth your dog has will change as they mature from puppyhood into adulthood.
Puppy Teeth
Puppies are toothless at birth and don't develop their puppy teeth until they reach three to four weeks of age. By the time they're three to five months old, they should have grown all 28 puppy teeth, which include incisors, canines, and premolars.
Adult Teeth
The eruption of adult teeth in dogs occurs between four and seven months of age (this timeline can vary between breeds and even differ depending on the dog). Dogs typically have 42 permanent teeth, unlike humans, who possess 32. Their upper jaw houses 20 teeth, whereas their lower jaw accommodates 22.
Types of Dog Teeth
Each type of tooth in a dog's mouth—incisor, canine, premolar, and molar—serves a specific purpose. Let's explore what each type of tooth does and where these teeth are located in your dog's mouth:
Incisors
What does your dog's smile reveal most prominently? The incisors of their teeth! These small teeth are located right in front of the upper and lower jaws, and dogs employ them for scraping meat and grooming their coats.
Canines
The canines, also known as "fangs," are a pair of long, pointed, and extremely sharp teeth located behind the incisors. Dogs use these teeth to tear into meat and grip objects. Dogs may also bare their canines if they feel threatened or defensive, so it's important to understand dog body language.
Premolars
Wide premolars, called carnassials, are located on both the top and bottom of a dog's jaw. Due to their sharpness, they play a crucial role in shredding and chewing.
Molars
Flat molars are at the very back of a dog's mouth, above and below. Your pup uses these to crunch on hard things like treats or kibble.
Why Dogs Lose Teeth
Dogs usually do not lose their teeth, except when transitioning from puppy to adult teeth. If you notice your dog losing its adult teeth, it is important to contact your veterinarian immediately to schedule a dental exam and cleaning.
Here are the most common reasons why dogs lose their adult teeth.
- Periodontal Disease - The most common reason a dog loses teeth is due to advanced dental disease. 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 through the process of trauma—whether it's caused by chewing something or sustaining another injury to their mouth. Some of the most common items that can cause fractures or loss of teeth are made from dense mineral or bone material. To protect your dog's teeth, it's best to avoid giving them beef bones or pork bones, as these materials can be too hard and commonly result in fractures and tooth damage.
- Tooth Decay - Dogs' teeth decay and experience wear and tear much faster 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 throughout their lives.
How to Prevent Dogs From Losing Their Teeth
Once dogs reach age three, many will have some form of periodontal condition, such as gingivitis. Brushing your dog's teeth regularly is essential to prevent dental disease. Providing dental chews and scheduling regular vet visits for thorough cleanings are also beneficial practices.
If you notice your dog having difficulty chewing or if you have concerns about their teeth or bad breath, don't hesitate to consult your vet for guidance on maintaining your pet's dental health. Make a veterinarian appointment promptly if you observe tooth loss, loose/wiggly teeth, or worsening breath.
Even if it appears that your pet has lost only one tooth, there may be more diseased teeth causing discomfort that would benefit from removal. Don't wait until your pet stops eating; use your pet's annual exam to discuss their teeth and overall dental health before any issues arise.
