How Often Should You Brush a Dog's Teeth? A Vet-Backed Answer

By PawNest Team

Dental disease is one of the most common, and preventable, health issues in dogs. Here's how often to brush and why it actually matters.

If the idea of brushing your dog's teeth sounds like a battle you don't have time for, you're not alone — most dog owners skip it entirely. But dental disease is quietly one of the most common health problems in dogs, and it's largely preventable with a habit that takes about two minutes a day. Here's how often you actually need to brush, and what happens if you don't.


Daily Is Ideal, But Consistency Matters More Than Perfection

Veterinary dental experts agree that daily brushing is the gold standard, but that doesn't mean anything less is pointless. [PetMD notes](https://www.petmd.com/general-health/how-often-should-you-brush-dog-teeth-and-cat-teeth) that brushing at least two to three times a week can still meaningfully reduce plaque buildup, even if daily isn't realistic for your household. The key is building a routine you'll actually stick with — a perfect daily habit that lasts two weeks and then quietly disappears helps your dog far less than three times a week, every week, indefinitely.

Why It Matters More Than Most Owners Realize

The scale of the problem is bigger than most people expect. According to PetMD, roughly 80 to 90 percent of dogs age three and older have some degree of dental disease, and [the AVMA notes](https://www.avma.org/resources-tools/pet-owners/petcare/pet-dental-care) that by age three, most pets already show early evidence of periodontal disease. Left untreated, plaque hardens into tartar, gums become inflamed and infected, and bacteria from the mouth can enter the bloodstream, with the potential to affect the heart, kidneys, and liver over time. It's a dental issue on the surface, but the consequences aren't limited to the mouth.

How to Actually Start Brushing

Go slowly, especially if your dog has never had their teeth brushed before. Start by letting them lick a dog-safe enzymatic toothpaste off your finger for a few days so they associate the taste with something positive, then gradually introduce a finger brush or soft-bristled dog toothbrush. Focus on the outer surfaces of the teeth, where plaque builds up fastest, and keep early sessions short — a few seconds is a win when you're starting from zero. Never use human toothpaste, which often contains xylitol or fluoride levels that are unsafe for dogs.

What to Do If Brushing Isn't Happening Yet

If your dog won't tolerate brushing, it's not all or nothing. Dental chews, water additives, and dental-specific diets can help reduce plaque as a supplement — none of them replace brushing entirely, but they're meaningfully better than nothing while you work on training your dog to accept a toothbrush. Watch for [signs of dental disease in dogs and cats](/blog/signs-of-dental-disease-in-dogs-and-cats), like bad breath, yellow or brown buildup on teeth, bleeding gums, or reluctance to chew — these mean it's time for a professional cleaning, not just more home care.

Professional Cleanings Are Still Necessary

Home brushing slows down plaque buildup, but it doesn't replace professional veterinary cleanings, which can reach below the gumline where brushing can't. Most dogs benefit from a professional cleaning roughly once a year, though your vet can recommend a schedule based on your dog's breed, age, and how their teeth look at checkups. Small and toy breeds in particular tend to be more prone to dental disease and may need cleanings more often. A good ear-cleaning routine is worth pairing with this too — see [how to clean a dog's ears](/blog/how-to-clean-a-dogs-ears) for the basics.


Frequently asked questions

**What if my dog won't let me brush their teeth at all?** Start with just letting them lick toothpaste off your finger, build up gradually over days or weeks, and lean on dental chews and diets in the meantime rather than giving up entirely.

**Can I use a washcloth instead of a toothbrush?** Yes — a soft, damp washcloth wrapped around your finger with dog-safe toothpaste is a reasonable substitute, especially for dogs that resist a brush.

**How do I know if my dog already has dental disease?** Bad breath, visible tartar, red or bleeding gums, and reluctance to eat hard food or chew toys are common signs worth a vet visit.

**Do small dogs need more dental care than large dogs?** Often yes — small and toy breeds are more prone to overcrowded teeth and periodontal disease, so they may need more frequent brushing and professional cleanings.
