How long should I brush my dog’s teeth?

Once your dog is used to it, VCA suggests at least 30 seconds on each side. While you’re training, keep it short — VCA’s behaviorist notes a session might be only 30 seconds at first, and the very first brushes may last a second or two before the reward.

Will brushing remove tartar that’s already there?

No. VCA notes that tartar has to be scraped off professionally, and the AVMA suggests having your pet’s teeth checked sooner if they look discolored or covered in tartar. Whether your dog needs a cleaning, and whether anesthesia is appropriate, is your vet’s call. Daily brushing is about keeping new plaque from turning into more tartar.

How often should I brush my cat’s teeth?

Daily, just like a dog. The Cornell Feline Health Center says daily toothbrushing can prevent most forms of dental disease, and some cats need a few weeks of gradual introduction. The AVMA notes cats tend to resist more than dogs, so patience matters. If your cat has badly inflamed gums, Cornell says brushing can hurt — see your vet first.

How Often Should I Brush My Dog’s Teeth? Daily vs. 3x a Week

Q: How often should I brush my dog’s teeth?

Once a day is ideal. If that isn’t realistic, aim for at least three times a week — VCA Animal Hospitals calls that the absolute minimum, and the AVMA says brushing several times a week can still be effective. Plaque can harden into tartar within about 48 hours, and tartar won’t brush off, so frequency matters more than effort. Cats benefit from daily brushing too; always use pet toothpaste.

Q: Can I use human toothpaste on my dog?

No — use a toothpaste made for pets. Dogs swallow toothpaste rather than spitting it out, and Cornell’s College of Veterinary Medicine says human paste isn’t recommended because it contains detergents and fluoride. Some human toothpastes also contain xylitol, which Cornell warns can cause severely low blood sugar, seizures or liver injury in dogs even in small amounts. The same goes for cats; the Cornell Feline Health Center says human toothpaste is not safe for them.

Q: My dog’s gums bleed when I brush. What should I do?

Stop, and call your vet if the bleeding is more than usual. A veterinary behaviorist writing for VCA Animal Hospitals advises contacting your vet if the gums bleed more than usual during brushing or you notice an unpleasant odor. Cornell lists bleeding from the mouth and bad breath among the possible signs of periodontal disease. If the gums are already red and bleeding, have your vet look before you carry on.

How often: daily is best, three times a week at minimum

Brush once a day if you can, and no less than three times a week. VCA Animal Hospitals says the best way to protect your dog’s teeth is brushing at least once daily, with three times a week as the absolute minimum to remove plaque and keep tartar from building up. The AVMA’s pet dental care brochure calls regular brushing the single most effective thing you can do to keep teeth healthy between dental cleanings — daily is best, but brushing several times a week can still be effective.

Why so often? According to VCA, plaque can harden into tartar within 48 hours, and once it does, it has to be scraped off professionally. Brushing at home works by removing plaque while it’s still soft, so a short daily brush beats a long weekly one.

Cats need daily brushing too. The Cornell Feline Health Center says daily toothbrushing can prevent most forms of dental disease. The AVMA points out that most dogs accept brushing but cats can be more resistant, so training takes more patience.

Getting started: build up one step at a time

Don’t start with a toothbrush on day one — introduce each piece separately and reward every step. Ellen Lindell, a board-certified veterinary behaviorist writing for VCA, lays out a sequence along these lines:

Pick a comfortable spot for both of you — a small dog might stand on a low table with a towel on it.
Reward your dog for standing still, building up a little each day until they can stay put for about two minutes.
Introduce the brush. Let them lick an easy-to-lick treat off it, then touch it briefly to the front teeth.
Introduce the toothpaste. Offer a dab of pet toothpaste and let them lick and swallow it.
Start brushing — just a second or two at first, then a reward. Once your dog is comfortable, VCA suggests brushing each side for at least 30 seconds.

If the handle feels clumsy, VCA suggests a soft fingertip brush instead. Some dogs take a few minutes to accept brushing; others take months. If you’re not making progress after a few weeks, VCA recommends getting help from a behavior consultant or trainer.

Toothpaste: pet toothpaste only

Use a toothpaste made for pets, never your own. Dogs don’t rinse and spit, so whatever goes on the brush gets swallowed. Cornell’s College of Veterinary Medicine says human paste isn’t recommended because it contains detergents and fluoride. Some human toothpastes also contain xylitol; Cornell warns that even a small amount can cause severely low blood sugar, seizures or liver injury in dogs, and advises using only dog-safe toothpaste. For cats, the Cornell Feline Health Center is just as clear: human toothpaste is not safe.

Beyond toothpaste, Cornell suggests looking for dental products with the Veterinary Oral Health Council (VOHC) seal, which is awarded only to products backed by supporting research. The AVMA adds that not every product marketed for dental health actually works, so it’s worth asking your vet before you buy.

Bleeding, bad breath or tartar: call your vet

If the gums bleed more than usual, the breath smells bad, or you can see tartar, have your vet take a look rather than brushing harder. VCA’s behaviorist advises contacting your vet if the gums bleed more than usual during brushing or you notice an unpleasant odor. The AVMA recommends a veterinary dental check at least once a year, and sooner if you notice:

Bad breath
Broken or loose teeth
Teeth that are discolored or covered in tartar
Abnormal chewing, drooling, or dropping food
Reduced appetite or refusal to eat
Pain or swelling in or around the mouth
Bleeding from the mouth

Cornell notes that by the time signs like mouth odor or bleeding appear, periodontal disease is usually already advanced. The AVMA also reminds owners that a pet in pain may bite, so be careful when checking the mouth yourself.

Brushing doesn’t replace a veterinary dental exam

Daily brushing keeps plaque from turning into tartar; existing tartar and anything below the gumline is a job for your vet. The AVMA explains that most dental disease happens below the gumline, out of sight, which is why a thorough cleaning and evaluation are done under anesthesia. Whether your dog needs a cleaning, how often, and whether anesthesia is right for them are decisions your vet makes with you.

What about “anesthesia-free” cleanings? The AVMA’s brochure states that the AVMA, the American Animal Hospital Association and the American Veterinary Dental College do not recommend them: they can’t clean or inspect below the gumline, and they can injure the pet or the person doing the procedure. If a cleaning comes up, talk it through with your vet.

Common mistakes

Using human toothpaste. It gets swallowed, and some ingredients aren’t safe for dogs.
Rushing the first sessions. A bad first experience makes every session after it harder.
Counting on the groomer. Cornell says brushing every month or two doesn’t deliver the benefits of daily brushing.
Brushing harder when the gums bleed. Stop and ask your vet.
Skipping the yearly dental check because you brush. Brushing and vet exams do different jobs.

How to remember

A daily habit sticks best when it’s attached to something you already do — brushing your own teeth before bed, say, or the evening walk. The real trouble with a daily job is not knowing whether today’s is done: with two or three people caring for the dog, each assumes someone else brushed, and a few hectic days can turn into a week without anyone noticing. Logging each brush shows who did it and which days were missed, and gives your vet a real answer about how often it happens.

While you’re handling the paws, check whether a nail trim is due, and use bath day for a closer look at the teeth and gums. When you replace your own toothbrush (see how often to replace a toothbrush), take a look at the dog’s brush too and swap it if the bristles are splayed.
