How to Brush Your Dog’s Teeth (A Beginner’s Guide)

There are two kinds of dog owners – the ones who brush, and the ones who find out at a four-figure dental bill that they should have. Brushing a dog’s teeth sounds fussy right up until you’ve smelled the alternative. The good news for beginners is that the hard part isn’t the brushing at all – it’s the fortnight beforehand, teaching your dog that a hand near the mouth is nothing to worry about.

Spend a week or two just handling the muzzle and letting your dog lick pet toothpaste off your finger before a brush ever appears. Then use a soft brush or finger brush and an enzymatic dog toothpaste (never human paste), work the outer surfaces at the gumline for about 30 seconds, and aim for daily. Brushing prevents disease – it can’t reverse tartar that’s already there.

Why bother brushing at all

Dental disease is the most common problem vets see in adult dogs, and most dogs carry some of it by the time they hit middle age. It starts as plaque along the gumline, which hardens into tartar and inflames the gums – that’s the source of the smell owners notice first. Left alone, the bacteria work below the gum and loosen teeth, and the low-grade inflammation can put strain on the heart, kidneys and liver. Daily brushing is the single most useful thing you can do at home, though it works best as prevention rather than a rescue.

Get the gear right first

You need two things, and neither is expensive. A soft brush comes first – a finger brush (a rubber cap with little bristles) is the easiest place for beginners to start, though a soft-bristled child’s brush works just as well and reaches further. Match the head to the mouth: a baby brush for a chihuahua, an adult brush for a labrador. Second is an enzymatic pet toothpaste, the kind sold in poultry, beef or peanut-butter flavours so the dog actually wants it – look for the ones from Virbac, Prozym or the PAW by Blackmores range at Pet shops. Never use human toothpaste; the fluoride and foaming agents are made to be spat out, and your dog will swallow the lot.

When to start and how often

Start young if you can. A pup that learns mouth-handling during teething treats brushing as normal for life, but plenty of adult dogs learn it too – it just takes more patience. As for frequency, daily is the gold standard, because plaque hardens into tartar within roughly 24 to 48 hours and brushing is what interrupts that cycle. Every other day still helps. Once a week, despite the good intentions, does almost nothing for the long run.

How to brush your dog’s teeth, step by step

Take each step at your dog’s pace and only move on when they’re relaxed. For some dogs that’s a few days; for the wary ones it can be weeks, and rushing is the fastest way to set yourself back.

1. Handle the muzzle first (a few days). At a quiet time, gently lift the lip, touch the gums and let go, then reward. This is the same desensitising groundwork you’d lay for nail trims or ear cleaning, and it’s the step most people skip.
2. Introduce the toothpaste. Let the dog lick a pea-sized blob off your finger so they decide it’s a treat, not a threat. If they’re unsure, smear a little on the back of your hand first.
3. Rub it on with a finger. Once they’re happy licking it, run a toothpaste-coated finger along the outside of a few teeth and the gumline for a couple of seconds, then reward and stop. Build up the number of teeth over several sessions.
4. Bring in the brush. Swap your finger for the finger brush or soft brush. Hold the head still and lift the lip – no need to prise the mouth open – and angle the bristles at about 45° into the gumline.
5. Work the outer surfaces (about 30 seconds). Use small circles, focusing on the canines and the big back cheek teeth where tartar gathers. The inside surfaces matter far less, so don’t fight for them. Finish every session with a treat, every single time.

The mistakes that put a dog off for good

Most failed brushing routines come down to the same handful of errors, and they’re all about the dog’s confidence rather than your technique.

• Forcing the mouth open. Dogs hate it, and one bad session can sour them for months. Brush the outsides with the mouth gently closed instead.
• Starting on a sore mouth. If the gums are already red or there’s heavy tartar, brushing hurts and teaches avoidance – sort the cooperative care and a vet check first, then build the habit.
• Going too fast. Jumping straight to the brush in week one is the classic beginner slip, and we’ve all been tempted by it.
• Chasing the inner surfaces. The tongue keeps the inside reasonably clean; the cheek-facing surfaces are where the damage happens, so spend your 30 seconds there.
• Brushing now and then. An occasional scrub does little. A short daily habit beats a thorough weekly one every time.

Brushing isn’t the only job

Brushing is the centre of home care, not the whole of it. Dental chews, dental diets and water additives can each shave off a bit of surface plaque, but none reach below the gumline, so treat them as helpers rather than replacements. Toy and brachycephalic breeds – chihuahuas, pugs and curly small dogs like cavoodles – have crowded mouths and tend to need the most help, so if you own one, the daily habit matters even more.

When it’s a vet job

Brushing prevents trouble; it can’t undo it. Book a vet check if you notice any of these:

• Fishy or rotten breath that doesn’t shift.
• Red, swollen or bleeding gums.
• Brown or yellow tartar crusted along the teeth.
• Dropping food, chewing on one side or pawing at the mouth.

Given that dental disease shows up in around 80% of dogs by age three, most dogs need a professional scale and polish at some point. That’s done under anaesthetic so the vet can clean below the gumline and check every surface – and it’s why you should steer clear of ‘anaesthesia-free’ or ‘gentle’ dentals, which only tidy the visible crown and miss the part that matters.

What it costs in Australia in 2026

Home care is cheap. A brush and a tube of enzymatic toothpaste runs about $10 to $25 and the paste lasts months. A professional dental under anaesthetic is the bigger number – commonly $300 to $700 in metro clinics for a scale, polish and check, and more once dental X-rays or extractions are involved, sometimes well past $1,500. Treat those as ballpark ranges rather than quotes, because they swing with your dog’s size and how much work the mouth needs. The cheaper path, by a wide margin, is the two minutes a day that keeps them out of the theatre.
