How to Clean Your Dog's Teeth at Home (Without a Fight)
Share
According to the American Veterinary Medical Association, most dogs and cats show some evidence of periodontal disease by age three. It is common, it is often painful, and a lot of it can be slowed down with a few minutes of care at home.
Why it matters
Plaque builds up on teeth every day. Left alone, it hardens into tartar and irritates the gums. Bad breath is usually the first sign owners notice, but by the time breath is bad, the process is well underway. At-home cleaning won't reverse existing tartar — that needs a vet — but it helps slow new build-up.
Start slowly, over a week or two
- Days 1–3: Lift your dog's lip for a second, praise, reward. That's it.
- Days 4–7: Rub a finger along the outside of the teeth and gums. Keep it short.
- Week two: Introduce a brush or brush-tip applicator with pet toothpaste, a few teeth at a time.
Always use toothpaste made for pets. Human toothpaste isn't meant to be swallowed, and dogs swallow it.
Focus on the outside surfaces
You don't need to open your dog's mouth wide or reach the inside of the teeth. Most build-up collects on the outer surfaces of the back teeth and canines, which you can reach by lifting the lip. Aim for a couple of times a week to start, and daily if your dog accepts it.
What helps between brushing
Chewing helps keep teeth cleaner, which is why textured chew toys are useful — they aren't a substitute for brushing, but they're a good daily habit.
When to see a vet instead
Book a vet visit if you see red or bleeding gums, a broken tooth, heavy brown tartar, swelling on the face, or if your dog drops food or chews on one side. Those need a professional, not a toothbrush.
What we use
The Pet Toothbrush Pen releases a little gel as you go, which makes it easier to do a few teeth quickly without juggling a tube and a brush. For daily chewing, the squeaky teeth-cleaning toy has a textured surface that dogs happily work on. For coat care, see how to brush a dog that hates being brushed.
