Making your own homemade dog toothpaste is appealing - it's cheap, natural, and you control what goes in it. But a quick search turns up dozens of recipes with zero mention of what's actually safe or whether any of it works. This vet-sourced guide gives you the honest version: safe DIY recipes with real caveats, how enzymatic dog toothpaste works, and what to do for the dog who simply will not let you near their mouth with a brush.
TL;DR: Never use human toothpaste on a dog - xylitol and fluoride are toxic. You can make a simple homemade paste (coconut oil + a pinch of baking soda + a little broth), but it isn't a proven plaque-reducer. Enzymatic toothpastes are the type vets most recommend because their enzymes keep working without perfect brushing. And if your dog refuses the brush entirely, a no-brushing option like our dog dental powder is the realistic path. Look for the VOHC seal.
Do You Need Special Dog Toothpaste? (Yes - Never Use Human Toothpaste)
Dogs can't rinse and spit, so they swallow everything you brush with - which makes human toothpaste dangerous. Many human pastes contain xylitol, a sweetener that's toxic to dogs and can trigger a dangerous blood-sugar crash within 10-60 minutes, plus liver damage at higher doses.2 Human toothpaste also contains fluoride in amounts not meant to be swallowed. Dog toothpastes are made to be swallowed safely and come in flavors like poultry and beef.1
What Is Enzymatic Dog Toothpaste and How Does It Work?
Enzymatic toothpaste is the type most recommended by veterinary dentists, and for good reason: it keeps working even when your brushing isn't perfect. It uses a system of enzymes - typically glucose oxidase and lactoperoxidase - that react to produce hydrogen peroxide and antibacterial compounds, suppressing the plaque bacteria that cause tartar and bad breath.3 Because the chemistry does part of the work, enzymatic paste is more forgiving than a plain abrasive paste for dogs (and owners) who can't manage a thorough scrub.
Safe Homemade Dog Toothpaste Recipes (With Honest Caveats)
If you want to DIY, keep it simple and safe:
- Basic paste: 1 tbsp coconut oil + a small pinch of baking soda + a few drops of low-sodium bone broth for flavor.
- Herbal variant: add a tiny amount of chopped parsley (breath) or a pinch of turmeric.
Caveats that matter: never add xylitol or use human toothpaste; go easy on baking soda (too much can upset the stomach if swallowed); and understand that homemade pastes are not proven to reduce plaque the way tested products are.4 Treat DIY paste as a gentle, better-than-nothing option - not a replacement for a vet-recommended product.
Homemade vs. Enzymatic vs. Dental Powder

How to Brush Your Dog's Teeth, Step by Step
- Go slow over several days. Let your dog lick the toothpaste off your finger first.
- Introduce the brush (or a finger brush) with paste, touching just a few teeth.
- Lift the lip and brush the outer surfaces at a slight angle toward the gumline.
- Aim for ~30 seconds per side, focusing where the tooth meets the gum (not scrubbing the gums raw).
- Reward generously. Keep it positive and short.
- Build to daily. Plaque starts hardening within 2-3 days, so frequency matters more than perfection.1
What If My Dog Refuses the Brush?
Plenty of dogs simply won't tolerate brushing - and a paste you can't apply does nothing. That's the gap a no-brushing option fills. The AKC itself lists dental powders among legitimate at-home dental-care methods.1 Our Dog Dental Powder is a 12-ingredient scoop you sprinkle on food - no brush, no paste, no wrestling. For the full breakdown of how powders work and how they compare, see our best dental powder for dogs guide.
How to Choose: VOHC Seal, Flavor & Brush Type
Whatever route you pick, look for the VOHC seal (the Veterinary Oral Health Council's mark for products proven to reduce plaque or tartar) as your quality filter.5 Choose a flavor your dog likes (compliance is everything), and pick the tool that fits - a finger brush for small or nervous dogs, an angled brush for larger ones.
Frequently Asked Questions
Can I make my own dog toothpaste?
Yes - a simple coconut oil, pinch-of-baking-soda and broth mix is safe. Just never add xylitol or use human toothpaste, and know that homemade paste isn't a proven plaque-reducer.
Is baking soda safe for dogs' teeth?
In tiny amounts as a mild abrasive, yes - but swallowing too much can upset the stomach, so use a pinch or skip it.
Does enzymatic toothpaste actually work?
Yes - its enzymes suppress plaque bacteria and it keeps working even without perfect brushing, which is why vets recommend it.
Can I use human toothpaste on my dog?
No - xylitol and fluoride are toxic to dogs. Xylitol can cause a dangerous blood-sugar crash within an hour.
What can I use if my dog won't let me brush?
A no-brushing dental powder, a brushless enzymatic gel, dental chews or water additives - then slowly work toward brushing if you can.
How often should I brush my dog's teeth?
Ideally daily, since plaque begins hardening within 2-3 days. Even a few times a week is far better than nothing.
The Bottom Line
Homemade toothpaste is fine as a gentle, budget option - just keep it xylitol-free and don't expect miracles. Enzymatic paste is the vet-recommended standard, and for the dog who refuses the brush, a no-brushing dental powder is the realistic way to actually protect their teeth.

Evidence note: Daily tooth brushing with a pet-safe paste is the home-care gold standard, but consistency matters more than method - the best routine is the one you'll actually keep up.
