No – human toothpaste isn't safe for dogs. It's not designed to be swallowed. And also, some dogs can't rinse and spit the way people do. So anything in the paste ends up ingested. Some human toothpastes also contain xylitol, which is toxic to dogs even in small amounts.
Here's what to use instead, what actually happens if your dog gets into your toothpaste and whether brushing is even necessary in the first place.
Do You Actually Have to Brush Your Dog's Teeth?
Yes. Plaque starts hardening into tartar within 24–72 hours and once it mineralizes, brushing can no longer remove it. See our guide on removing tartar from dog teeth for more.
Skipping brushing doesn't just mean cosmetic buildup – it's the leading path to gum disease and eventual tooth loss in dogs. Daily brushing is the standard recommendation; if that's not realistic, aim for at least 3–4 times a week supplemented with a dental chew or dental powder.

Why Human Toothpaste Isn't Safe
The short version: Human toothpaste is built for spitting, not swallowing, and dogs can't do the first. Two ingredients make this more than just a preference issue – xylitol (toxic to dogs even in small amounts) and fluoride (not meant to be ingested repeatedly in the quantities a dog would swallow).
For the full breakdown of what makes a toothpaste dog-specific and what to check on an ingredient label, see our guide on dog-specific toothpaste.
What to Do If Your Dog Already Ate or Licked Human Toothpaste
A single lick off a dropped tube is a different situation than a dog getting into and swallowing a significant amount, so the right response depends on how much and what kind.
Here's what you can do:
- Check the ingredient list first. If the toothpaste contains xylitol, treat it as a potential emergency – xylitol toxicity in dogs can develop quickly and this is not a "wait and see" situation. Contact your vet or a pet poison hotline immediately.
- Watch for symptoms such as vomiting, weakness, loss of coordination or lethargy and seek veterinary care promptly if any appear – don't wait for a full symptom list before calling.
- For a small lick of a fluoride (non-xylitol) toothpaste, mild stomach upset is the most likely outcome, but it's still worth calling your vet if your dog seems unwell or if you're unsure of the ingredients.
- When in doubt, call. It's always a good id to check with your vet or a poison control line. Why? Because toothpaste ingredients vary enough that guessing isn't worth the risk.
Keeping toothpaste tubes out of reach – the same way you would medication – is the simplest way to avoid this situation entirely.
What Can You Brush Your Dog's Teeth With Instead?
If you're out of dog toothpaste and need a stopgap, or you're just starting a brushing habit and haven't bought any yet, here's what you can do:
- Plain water on a soft-bristled brush or finger brush is a safe, if less effective, placeholder. It won't provide enzymatic plaque support, but the mechanical brushing action still helps.
- A clean, damp washcloth or gauze wrapped around your finger, gently rubbed along the teeth and gumline, works as a no-toothpaste option for puppies or dogs just getting used to having their mouth handled.
- Dog-specific enzymatic toothpaste is the actual long-term answer, not a workaround – it's formulated to be swallow-safe and includes enzymes that support plaque breakdown beyond what water or a cloth alone can do.
- Avoid homemade pastes with baking soda or salt in any real quantity – small amounts are generally considered low-risk, but there's no reliable dosing for dogs and it offers no real advantage over purpose-made formula.
Water or a cloth are fine for a day or two in a pinch – they're not a long-term substitute for a proper dog toothpaste.
FAQs
Can dogs use human toothpaste?
No, dogs can't and shouldn't use human toothpaste. Human toothpaste isn't designed to be swallowed, it's designed to be spat out. The catch is that dogs can't rinse and spit like people do, so the intention of the formula and method of action isn't compatible for dogs.
Some formulas also contain xylitol, which is toxic to dogs, or fluoride, which isn't meant to be ingested in the quantities a dog would swallow during brushing. So, there's literal formulation and ingredient differences that really can be enough to worry about when it comes to your dog. Always use a toothpaste made specifically for dogs.
What happens if my dog eats toothpaste?
What happens to your dog if they eat human toothpaste, depends on the ingredients and the amount of toothpaste they've ingested. If the toothpaste contains xylitol, treat it as urgent and contact your vet or a pet poison hotline right away, because xylitol toxicity can develop quickly.
For a small amount of a non-xylitol, fluoride-based toothpaste, you'll usually expect mild stomach upset, which isn't a risky outcome, but it's still worth a call to your vet if your dog seems unwell or you're not sure what was in the tube. They can check and confirm the appropriate next steps for your dog.
Do you actually have to brush your dog's teeth?
Yes, you do have to brush your dog's teeth. Without regular brushing, plaque can build-up and harden, turning into tartar within a few days. When it becomes tartar, it's no no longer able to be removed by daily brushing. This is where you'll have to take a trip to the vet to help.
Tartar build-up often progresses to gum disease over time, which is definitely something that you want to avoid for your dog. So, what can you do? Daily brushing is ideal; 3–4 times a week with a dental chew or dental powder on other days is a reasonable minimum.
What can I brush my dog's teeth with if I don't have dog toothpaste?
If you don't have dog toothpaste, you can use plain water on a soft brush, or a damp washcloth wrapped around your finger. Both of these methods work as short-term options, but of course, neither replaces a proper enzymatic dog toothpaste.
This type of dog-specific toothpaste offers plaque-breakdown support that water alone just doesn't. If it's temporary and interim, brushing with just water is usually okay for a few days until you're able to start using dog toothpaste to clean their teeth again. There are also the options of dental chews, dental powder and dental wipes as supplements and accessories that can really help.
Is it okay to use baking soda as dog toothpaste?
It's not recommended to use baking soda as dog toothpaste, no. While using small amounts of baking soda are generally considered low-risk, there's no reliable guidance for dogs, which isn't something that you want to trust. If consumed in larger amounts, it can upset digestion and it doesn't offer the enzymatic plaque support of a dog-specific formula.
Dog-specific toothpastes are formulated with specific enzymes that help to break down the plaque that's sitting on their teeth more effectively than a standard human toothpaste. It also doesn't contain any of the harmful chemicals that a human toothpaste does. A purpose-made dog toothpaste is the safer and more effective choice.
To Sum Up
Human toothpaste isn't safe for dogs because of how it's formulated and because dogs can't spit it out. Always reach for a dog-specific, enzymatic toothpaste instead.
If your dog does get into your toothpaste, check the ingredients, watch for symptoms and call your vet if there's any xylitol involved or anything seems off. In a pinch, water or a damp cloth can bridge the gap, but they're not a substitute for the real thing long-term.
