Is a Dog’s Mouth Cleaner Than a Human’s Mouth?

The saying, "a dog's mouth is cleaner than a human's mouth," has been around for a long time. However, is it true? In this blog post, our veterinarians in Maury County address this age-old question.

Is a dog's mouth cleaner than a human's?

When comparing a dog's mouth to a human's mouth, it's like comparing apples and oranges. While there is some overlap in the types of bacteria between species, dogs' mouths contain a variety of dental bacteria that you won't find in yours.

Dogs' mouths have about 600 different species of germs, compared to 615 and counting varieties in human mouths. 

In short, the answer is no. However, there are similarities. For example, Porphyromonas is a bacterial family that causes periodontal disease in both canines and humans.

Billions of germs slowly build up on the surface of the teeth, causing bad breath, gum recession, tooth root abscesses, and bone damage around the tooth roots. Periodontal disease's early stages are treatable in dogs and humans with at-home dental care. Like humans, dogs require professional cleaning regularly.

Can you get infections & diseases from dog saliva?

The chance of germs being transmitted to humans through a dog's saliva is extremely minimal. However, it still has a chance of happening. Through their saliva, dogs can spread bacterial and viral illnesses. These can be transmitted if a dog bites you or saliva goes into your nose, mouth, or eyes.

Bacterial Infections

A dog bite can transmit the bacteria Capnocytophaga canimorsus through the bite wound, resulting in a severe bacterial infection in humans. Another, Pasteurella canis, is the most common bacteria found in a dog's mouth; it is also the most common organism found in a person a dog has bitten. The location of the wound determines the severity of a dog bite wound and whether the person is immunocompromised or vulnerable in some other way.

If a dog bites you, wash the wound thoroughly with soap and water for 15 minutes before seeking medical attention. If your dog consumes food contaminated with Salmonella or E. coli, these pathogens may be transmitted to you if your dog's slobber enters your mouth. A raw food diet is more prone to contamination, but any dog food can become contaminated.

Rabies

The most serious infection dogs can transmit through their saliva is rabies. It's a virus that spreads when a dog bites someone. The virus infiltrates the nervous system, causing a variety of symptoms. Dogs may exhibit anxiety and nervousness at first. In later stages, they become aggressive, uncoordinated, and disoriented.

If you see a dog (or wild animal) exhibiting these symptoms, contact your local animal control or police department and keep your distance. When a dog, person, or wild animal develops symptoms of rabies, it is almost always fatal.

Is it bad if your dog licks you then?

Because your skin absorbs saliva poorly, there is little risk of infection if a dog licks your skin (as long as they are not licking a wound). If you are allergic to dog saliva, your skin may develop hives, a rash, and/or become extremely itchy.

How to Clean a Dog's Mouth

Proper dog dental care, and learning how to clean your dog's teeth, are essential in making sure your dog's mouth is as clean and safe as possible. One of the easiest ways to do this is to bring your dog in for a dental appointment. We recommend at least once a year or more if your dog suffers from dental disease (like periodontitis).

When you bring your dog to Veterinary Wellness Clinic of Columbia for a dental checkup, our vets will perform a full oral examination for your dog and check for signs of dental issues, such as:

  • Extra teeth or retained baby teeth
  • Bleeding around the mouth
  • Swelling or pain in or around the mouth
  • Plaque or tartar buildup on teeth
  • Discolored teeth
  • Loose or broken teeth
  • Bad breath

If oral health problems in pets are left untreated, they can become severe, causing a great deal of pain and discomfort. If you notice signs of periodontal disease in your pet, such as decreased appetite (indicating tooth pain), abnormal chewing, drooling, dropping food from the mouth, bad breath, or other symptoms, contact your veterinarian right away to schedule a dental appointment for your pet.

During the appointment, we thoroughly clean and polish your dog's teeth, both above and below the gum line. We also probe and x-ray the teeth, followed by a fluoride treatment and a dental sealant to help prevent future decay and damage. If your dog has advanced periodontal disease, we will work with you to create a treatment plan to help restore its mouth to a pain-free and healthy state.

Should I brush my dog's teeth?

As a pet owner, you play an important role in helping your dog fight dental disease. Here are a few simple ways you can help keep your dog's mouth healthy and clean his teeth:
  • Brush your pet's teeth daily with a finger brush from your vet or a child's toothbrush to remove any plaque or debris. It's as straightforward as brushing your own teeth. If your dog resists having its teeth cleaned, try some doggie toothpaste in flavors your dog will love. These dog-friendly toothpaste can transform a chore into a treat.
  • Use a plaque prevention product (your vet can recommend some), which you can apply to your pet’s teeth and gums. These products act as a barrier to prevent plaque buildup.
  • Offer your pup treats such as dental chews or food designed to help prevent plaque buildup and tartar.

Dental care is an important part of your pet's overall health. Be sure to book your pet's annual dental appointment today. Your dog will thank you.
