Can you use human toothpaste on dogs? It’s a valid question. Some of the medications which veterinarians prescribe for dogs are human drugs obtained from human pharmacies. Also, as pet parents, we share almost everything with our furry friends—from our deepest thoughts to our pillows. So while we might draw the line at sharing our toothbrushes with our dogs, does it really matter if we share our toothpaste? Turns out the answer is, “Yes, it does matter.” Do not use human toothpaste on your dog’s teeth. Integrative veterinarian Dr. Julie Buzby outlines three reasons why human toothpaste poses a health hazard for your dog.
3 critical reasons why human toothpaste is dangerous for dogs
Although we know that some of the medications and supplements we take are safe for use in dogs, human toothpaste is certainly not on that list. There are three components of human toothpaste that make it unsafe for dogs:
Fluoride, in high enough doses, is toxic to dogs. Human toothpaste is designed to be rinsed out of the mouth, not swallowed. Do you know how hard it is to convince a four-year-old child not to swallow toothpaste, let alone a Labrador?!
While acute fluoride toxicity is possible (a large dose of fluoride consumed at once), the more likely scenario is chronic toxin exposure, where the fluoride ingestion from frequent use (over the course of months to years) eventually reaches toxic levels in the dog’s body. The symptoms are considerably different in the two scenarios.
Signs of acute fluoride toxicity from a dog ingesting a large amount of human toothpaste include:
- Rapid, irregular heart rate
- Fecal and urinary incontinence
- In severe cases, death may occur
In acute fluoride toxicity in dogs, the fluoride is absorbed quickly, and acute toxic effects may be seen within 90 minutes of ingestion.
Symptoms of chronic toxicity from a dog ingesting a small amount of human toothpaste over time include:
- Discoloration and mottling to the teeth
- Intermittent limping (high levels of fluoride can bind up calcium and replace some of the calcium in bones)
- Poor appetite and weight loss
Even pet toothpaste may contain fluoride
While dog toothpaste is formulated to be swallowed, you still need to check the label on toothpaste formulated for pets before purchase. There are doggie

2. Sodium Lauryl Sulfate (SLS)
Next, let’s look at another component of human toothpaste that’s unsafe for dogs: Sodium Lauryl Sulfate.
To create the foaming action, manufacturers add a chemical called Sodium Lauryl Sulfate (SLS). SLS is present in soaps, shampoos, laundry detergents, and
In dogs, SLS can cause gastrointestinal upset if swallowed in sufficient quantities. Now you know “the rest of the story” on why pet toothpaste doesn’t foam, and another reason why “no” is always the answer to the question, “Can you use human toothpaste on a dog?”
There’s nothing sweet about our third reason why human toothpaste poses a hazard to dogs.
You may have heard about xylitol, an increasingly common artificial sweetener in human foods and hygiene products. Ironically, xylitol has been associated with preventing tooth decay in
I think it might surprise you to learn how prevalent this dangerous chemical is in human toothpaste, including some well-known “holistic” brands such as Tom’s of Maine®, Trader Joe’s®, and Young Living™. (For more human dental products containing xylitol, please refer to Preventive Vet’s list of products containing xylitol.)
Sadly, xylitol and dogs are a deadly mix. Xylitol can cause two problems for a dog’s system: low blood sugar and irreversible damage to the liver, both of which can be fatal.
Please get in the habit of checking the label (and check in with your vet!) for everything you give your dog. Be sure to watch for xylitol (i.e. birch sugar) in the ingredient list.
Now that you know the three reasons why dogs and human toothpaste don’t mix, you may be wondering about toothpaste formulated specifically for dogs. What are the benefits of dog toothpaste? What dog toothpaste should you use? Let’s discuss this.
How valuable is dog toothpaste for your dog’s dental health?
Here’s the truth: the real benefit of routine home dental care for your dog isn’t from the dog toothpaste itself. It’s the physical act of brushing—the repetitive motion of the bristles scrubbing away food particles and plaque deposits in the mouth—that makes brushing your dog’s teeth so valuable.
When you take your car to the DIY car wash, is it the pink soap that cleans the dirt and debris from your car, or is it your elbow grease? Consistency and good technique are far more valuable than the animal-safe toothpaste you use. Brushing your dog’s teeth with plain water is reasonable.
A dog toothbrush, which can be found at most pet stores, online retailers, or at your veterinarian, is specially designed to reach into your dog’s mouth and safely brush plaque and bacteria off the teeth.
If your dog is at risk for dental diseases, your vet may even recommend a prescription dog food to promote oral health!
For some tips on how to incorporate dental care into your dog’s daily routine, see my article: Should I Brush My Dog’s Teeth? 7 Toothbrushing Tips.
So why do we even use pet toothpaste for dogs?
The manufacturers claim that pet toothpaste does help reduce plaque, but I don’t know of any scientific research that proves this. The real benefit of using dog toothpaste when brushing your dog’s teeth is probably the flavor. Supposedly, animals don’t like the taste of human toothpaste (mint), but veterinarian-recommended pet toothpaste comes in such decadent flavors as poultry, malt, beef, and seafood.
Recently, one of my veterinary clients told me she was surprised by how much her dog liked the taste of the dog toothpaste. In fact, her dog seemed to enjoy having his teeth brushed because of it.
That’s the real advantage of doggie toothpaste—keeping the experience a positive one for your canine companion. Tooth brushing can be a little treat!
Which dog toothpaste should I use?
As with many pet products, the market is flooded with options for dog toothpaste. So how do you choose which one to use?
Generally, I recommend an enzymatic cleaning toothpaste, such as Virbac C.E.T. Enzymatic Toothpaste.
As we’ve learned, the mechanical aspect of brushing is more valuable than the enzymatic action in toothpaste. However, these types of dog toothpastes have potential benefits. Here are common enzymatic ingredients and their respective actions:
- Lactoperoxidase, lactoferrin, and lysozyme: These enzymes reduce plaque by killing the bacterial, fungal, and viral components and free radical scavengers which also target the organism’s cell membrane or cause iron deprivation. Dental products may contain one, two, or all three of these enzymes.
- Mutanase and dextranase: These enzymes keep plaque from sticking to the teeth by breaking apart plaque’s glycan bonds, thus causing it to be water-soluble.
- Papain: This enzyme reduces plaque build-up by keeping a plaque component—salivary glycoproteins—from accumulating in the pet’s mouth.
Dog toothpaste containing these ingredients can give added benefits to the mechanical component of tooth brushing.
Human toothpaste for dogs? I don’t think so!
Finally, when someone asks you, “Can you use human toothpaste on dogs?” I hope that you’ll respond with an emphatic “No!” and explain the dangers of using human toothpaste. Kudos to anyone enthusiastic about brushing their dog’s teeth, but remember to read the label on over-the-counter pet toothpaste before use, or buy from your veterinarian to protect the health of your dog.
What questions do you have about brushing your dog’s teeth?
Please comment below.
I was brushing my teeth. My chihuahua wanted a pet. I had a tiny bit of Pepsodent on my fingers. I tried to wipe it off before I touched her. She was acting a bit weird for a minute. Should I be worried? Take her to the er?
Julie Buzby DVM says
I wouldn’t think a trace amount of toothpaste that was accidentally touched to the skin of your dog would cause a problem. If you think your pup is exhibiting strange symptoms, then I always think it is best to contact your vet and seek their advice.
Thank you so much for the useful information! Wish this was known by more people!
Dr. Julie Buzby says
Thank you so much for your kind words. We aim to arm pet owners with accurate and applicable information so it always makes us happy when we hear our articles accomplish that goal.
anthony martin says
You still have not told any of us what is the name of the doggie toothpaste that tastes like chicken for my dog to use ? Thanks
Julie Buzby, DVM says
Hello Anthony. My apologies! 🙂 This is what I recommend: Virbac C.E.T. Enzymatic Dog & Cat Poultry Flavor Toothpaste
Where are the studies that show these enzyme toothpastes are effective against plaque, cavities & gum disease?
Dr. Julie Buzby says
This is a good question and I think your point is well taken. The mechanical aspect of brushing is surely more valuable than any potential enzymatic action. Here are common enzymatic ingredients and their respective actions:
~ Lactoperoxidase, lactoferrin and lysozyme: These enzymes reduce plaque by killing the bacterial, fungal, and viral components and free radical scavengers which also target the organism’s cell membrane or cause iron deprivation. Dental products may contain one, two, or all three of these enzymes.
~Mutanase and dextranase: These enzymes keep plaque from sticking to the teeth by breaking apart plaque’s glycan bonds, thus causing it to be water soluble.
~Papain: This enzyme reduces plaque build-up by keeping a plaque component – salivary glycoproteins- from accumulating in the pet’s mouth.
I don’t have any specific studies to cite about these products, but hopefully understanding the proposed mechanism of action is helpful. I would also recommend you check out the Veterinary Oral Health Council website because it is a great resource for learning more about the different oral health product options. The site outlines in detail the process required for a product to get the VOHC seal of acceptance. Thanks for asking!
Caitlyn Hill says
What about fluoride free, natural children’s toothpaste? As long as it doesn’t have those other ingredients mentioned wouldn’t be okay to use in dogs in small quantities?
Julie Buzby, DVM says
Hello Caitlyn, even if you were to ensure that there were no toxic ingredients in the natural chidren’s toothpaste, dogs don’t love the taste of human toothpaste, which would decrease the “joy” factor in the experience. We absolutely want to keep it positive and fun! Keep in mind that human toothpaste of any variety is not designed to be eaten. However that’s exactly what happens with dog teeth brusthing. Dogs like to lick it right off–so I recommend a dog toothpaste hands down, but any version (human or pet) of soft-bristled tooth brush is fine.
Linda Brodowski says
I’ve been brushing my dog’s teeth with Raw Extra Virgin Organic Coconut Oil for months now…it seems to work well plus he gets the added GI benefits that go along with using this. About 1/2 tsp does well on cleaning his teeth. He’s 10lbs anfd loves when I brush : )
Julie Buzby says
My only concern with recommending that across the board is that I have heard of dogs getting pancreatitis from too much coconut oil (fat content) and it is high calorie. But I’m sure if used sparingly, as your describe, it makes sense. Thanks for the comment, Linda!
