Can Dogs Use Human Toothpaste?

Quick Takeaway – Is Human Toothpaste Safe For Dogs?

  • No, dogs cannot use human toothpaste.
  • Human toothpaste is not safe for dogs. Xylitol, a common sweetener in human toothpaste, is highly toxic to dogs and can cause life-threatening conditions like hypoglycemia, seizures, and liver failure.
  • Dog-specific toothpaste often comes in flavors like chicken, beef, or peanut butter, making the brushing experience more enjoyable for your pup.
  • Many dog toothpastes contain enzymes that help break down dirt build-up, making it effective even if you can only smear the toothpaste on your dog’s teeth without thorough brushing.

Many pet owners might wonder, “Can dogs use human toothpaste?” It’s a common question, especially when your own toothpaste is within reach. But is human toothpaste safe for dogs? 

Human toothpaste is not safe for dogs. Unlike humans, dogs don’t spit out toothpaste, meaning they ingest whatever is used during brushing, making it crucial to avoid human toothpaste as it may contain harmful ingredients.

Regular brushing helps prevent plaque buildup, gum disease, and other dental issues that can lead to serious health problems. But brushing your dog’s teeth with human toothpaste should never be considered an option, even if you run out of dog-friendly canine toothpaste.

Pet owners unknowingly using harmful toothpaste for dogs happens more often than you may realise. In 2018, UK food brand Lily’s Kitchen surveyed 2000 pet parents, asking whether they’d ever used human toothpaste while brushing their dog’s teeth. The answer was alarming – 8% said they had used human toothpaste on their dog’s teeth!

Is Human Toothpaste Bad for Dogs?

Yes, due to the typical ingredients, human toothpaste is bad for dogs. Artificial sweeteners often used in human toothpaste are toxic for dogs, and using human toothpaste on dogs is ineffective, as well as potentially dangerous. Here’s why:

Certain Ingredients in Human Toothpaste Are Unsafe For Dogs

Before you reach for your own toothpaste to brush your dog’s teeth, it’s important to understand what’s inside. Common ingredients in human toothpaste can include:

  • Artificial sweeteners like xylitol
  • Fluoride
  • Foaming agents

Using human toothpaste on dogs is not only ineffective but can also be dangerous. Here’s why:

Xylitol in Human Toothpaste Is Not Safe For Dogs

One of the most dangerous ingredients in human toothpaste for dogs is xylitol, a common artificial sweetener. Xylitol, also known as birch sugar, is safe for humans but can cause life-threatening conditions in dogs, such as hypoglycemia (low blood sugar), seizures, and liver failure. Even small amounts can be toxic, so it’s crucial to avoid using any product containing xylitol on your dog.

Ingestion of Fluoride Can Be Dangerous for Dogs

While fluoride helps strengthen human teeth, it can be harmful to dogs. Fluoride is a naturally occurring mineral that strengthens enamel (the protective layer on the teeth) and prevents cavities. Fluoride is deemed safe to use in human toothpaste but it is not a safe ingredient in toothpaste for dogs. 

Dogs don’t spit out toothpaste like humans do, which means they swallow everything during brushing. Ingesting too much fluoride can lead to gastrointestinal issues, such as vomiting, diarrhea, and more severe symptoms like muscle tremors or seizures in extreme cases.

Foaming Agents and Flavorings in Human Toothpaste Can Be Harmful to Dogs

Human toothpaste often contains foaming agents and strong flavorings, which can be unpleasant or even harmful to dogs. The foaming action can cause gastrointestinal upset, while the flavors may be too intense for a dog’s sensitive nose and palate, leading to resistance during brushing.

What Can I Use Instead of Human Toothpaste For Dogs?

So, if the answer to “can you brush dogs’ teeth with human toothpaste?” is no, what should you use to clean your pup’s teeth instead?

Dog-Specific Toothpaste Is A Safe Alternative To Human Toothpaste

The best option is to use toothpaste specifically formulated for dogs. Dog toothpaste is designed to be safe if swallowed and comes in flavors that dogs enjoy, such as chicken, beef, or peanut butter. These flavors make the brushing experience more pleasant for your pet and help ensure that they tolerate regular brushing.

How Dog Toothpaste Differs from Human Toothpaste

Dog toothpaste is made with ingredients that are gentle on your dog’s teeth and gums. Unlike human toothpaste, it doesn’t contain potentially harmful ingredients for dogs like xylitol, fluoride, or strong abrasives. The formulations are tailored to effectively clean a dog’s teeth while being completely less of a risk in swallowed.

According to Dr. Jamie Clanin, US DVM, PetLab Co. Consultant, “In addition to being made without these harmful ingredients, it is made with other ingredients that make it more effective in a dog’s mouth. Many dog toothpaste brands contain enzymes, which are proteins that help break down plaque in the mouth. This means that even if your dog won’t let you scrub away in their mouth, even smearing the toothpaste on the surface of their teeth will help!”

Where to Find Dog Toothpaste

You can find dog-specific toothpaste at most pet stores, online retailers, and even some veterinary offices. It’s important to choose a reputable brand that offers quality ingredients and flavors your dog will enjoy.

To be sure the brand you’re using is the best you can give your pup, look for the seal from the Veterinary Oral Health Council (VOHC).

What to Do If Your Dog Accidentally Ingests Human Toothpaste

Accidents happen, and if your dog ingests human toothpaste, it’s important to act quickly.

Immediate Actions

If you suspect your dog has ingested human toothpaste, contact your veterinarian or an emergency pet poison hotline immediately. Do not wait for symptoms to appear, as early intervention is crucial.

Signs of Toxicity

Watch for symptoms such as vomiting, drooling, lethargy, weakness, or seizures. These could indicate toxicity, particularly if the toothpaste contains xylitol or fluoride.

Prevention Tips

To prevent accidental ingestion, always store toothpaste and other personal care products out of your dog’s reach. Keep your bathroom door closed, and consider using childproof locks on cabinets if your dog is particularly curious.

Can Dogs Use Human Toothpaste? Final Thoughts

In summary, while regular teeth cleaning dental care is vital for your dog’s health, using human toothpaste for dogs is not safe. The best dog toothpaste is one that is specifically formulated for pets. By choosing the right products, maintaining a regular dental care routine, and taking your dog to annual veterinary dental cleanings, you can help ensure your dog’s teeth and gums stay healthy for years to come.
