How to Brush Your Dog's Teeth: Stress-Free Guide

Brushing your dog's teeth works stress-free when you build up gradually over about two to four weeks. With a soft dog toothbrush or a finger brush and special dog toothpaste, you clean the outer surfaces of the teeth ideally every day, but at least three times a week. Once your dog is trained, the daily routine takes around two minutes.

This guide does not replace veterinary advice.

Why is brushing your dog's teeth worthwhile?

Is it worth brushing your dog's teeth? Veterinary medicine today answers with a clear yes. For a long time, bad breath in dogs was considered a normal part of ageing. Studies show, however, that around 80 percent of all dogs over three years old suffer from periodontal disease. The cause is a simple biological process: after every meal, a soft biofilm of food residue, saliva components and bacteria forms on the teeth – known as plaque.

If this soft coating isn't removed mechanically, minerals from the saliva are deposited within 24 to 72 hours. After three to five days at the latest, the plaque hardens into solid tartar. This rough tartar gives more bacteria an ideal surface to settle on. Gum inflammation (gingivitis) develops, and if left untreated it turns into periodontitis. As the German Federal Veterinary Chamber (Bundestierärztekammer) explains, periodontitis permanently destroys the connection between tooth and tooth socket, the gums recede and the teeth loosen painfully. In addition, bacteria collect in the gum pockets that form and can enter the bloodstream through tiny bleeds, where they can damage internal organs such as the heart, liver or kidneys.

Small and short-nosed breeds in particular – such as the Yorkshire Terrier, the Pug or the Miniature Poodle – tend to develop tartar early because of crowded teeth and altered saliva flow. A Swedish study, reported on by the vets at aktion tier e.V. among others, shows how quickly home care pays off: after just seven days of daily brushing, existing gum inflammation and bacterial plaque fell significantly in the dogs studied, while the animals' stress levels during the procedure dropped from day to day.

An honest assessment: a real toothbrush vs. chews and sprays

The market for dental care products is huge, but not everything that's promised stands up to veterinary scrutiny. Experts at the University of Veterinary Medicine Hannover (Stiftung Tierärztliche Hochschule Hannover) stress in their dental hygiene recommendations that manually cleaning the tooth surfaces with a toothbrush remains by far the most effective tool. Sprays, water additives or powders can no more replace mechanical brushing than they can for humans.

And what about dental chews? Firm chewing stimulates saliva flow and provides a certain amount of mechanical abrasion, especially on the tips of the molars. However, dogs usually bite down on chew bones with just a few specific teeth at the back of the jaw; the sensitive incisors and canines, as well as the all-important gum line where gum meets tooth, barely get cleaned. On top of that, extremely hard materials such as antler pieces or solid marrow bones carry a risk of painful tooth fractures. Chews, and dental sticks tested by the independent Veterinary Oral Health Council (VOHC), are therefore a sensible addition, but not an equal replacement for regular brushing.

Brushing your dog's teeth: a step-by-step guide without force

If you want to brush your dog's teeth, the way you build up the training decides whether it works. Dogs rarely object to the brushing itself. What they object to is having their head gripped without warning and a strange object put in their sensitive muzzle. With positive medical training, your four-legged friend learns to cooperate willingly. Only move on to the next step once the current one works with your dog completely relaxed.

1. Get the right preparation and equipment
   Why: The wrong materials can hurt the gums or even be toxic to your dog, which undermines the training straight away.
   How: Get a special dog toothbrush with soft bristles (a soft child's toothbrush also works) or, to start with, a microfibre finger brush. You'll also need a dog toothpaste, which usually comes in poultry or liver sausage flavour. Choose a quiet spot – such as a firm blanket or the sofa – and always practise at a similar time of day after a walk, when your dog is relaxed.
2. Build a positive association through taste
   Why: Your dog should store dental care as a sign that a reward is coming, not as an annoying chore.
   How: Put a small dab of dog toothpaste on your index finger and let your dog simply lick the paste off. To your dog, the paste feels like a special treat. Repeat this briefly for two to three days, without holding his head or pulling up his lips.
3. Practise touching the muzzle and lifting the lips
   Why: The muzzle is covered with fine whiskers and is very sensitive to touch; grabbing it without asking triggers avoidance behaviour as a reflex.
   How: Introduce a fixed cue word, for example “teeth”. Gently stroke your dog's cheek, lift the upper lip slightly for one second, release it straight away and reward him with toothpaste or a small treat. Slowly increase the duration over several days to five to ten seconds.
4. Get used to rubbing along the gums (finger or finger brush)
   Why: Before stiff bristles go into the mouth, your dog needs to get to know the feeling of light pressure on his teeth and gums.
   How: Spread a little toothpaste on your bare finger or a dampened finger brush. Lift the lip at the side and, using gentle circular movements, rub for a few seconds over the large canines (fangs) and the surrounding gums. Leave the front incisors out completely for now – they're the most ticklish and sensitive.
5. Introduce the toothbrush
   Why: The unfamiliar feeling of nylon bristles in the mouth can frighten a dog if he hasn't been allowed to explore the tool in peace first.
   How: Dampen the soft toothbrush, press the dog toothpaste deep between the bristles (so it isn't just licked off the top) and hold the brush out to your dog. Let him sniff it and lick the paste from the bristles. That way he already feels the texture of the brush on his tongue and teeth, of his own accord.
6. First brushing of the canines and molars
   Why: The openings of the large salivary glands sit by the upper back molars – that's exactly where most tartar forms.
   How: Place the toothbrush at a 45-degree angle against the gum line of a canine. Brush with gentle pressure in light circular motions or from “red to white” (from the gum towards the tip of the tooth). Over several days, work your way back from the canines to the molars. Often you don't even need to open the mouth wide: it's enough to slide the toothbrush into the cheek pouch with the muzzle closed.
7. Complete the routine: incisors and finishing up
   Why: Only once the sides work reliably will your dog accept brushing right beneath the sensitive tip of his nose.
   How: Carefully lift the front lip and briefly brush over the small incisors of the upper and lower jaw. In everyday care, limit yourself to the outer surfaces of the teeth: dogs largely clean the inner surfaces themselves through the constant friction of their rough tongue. End every dog teeth brushing session with a cheerful release cue and a short play or cuddle session.

When to start brushing your dog's teeth: a schedule by age and training stage

Many dog owners wonder when to start brushing a dog's teeth. As a rule: the earlier you start getting your dog used to it, the more natural the ritual becomes. But even an adult rescue dog can still learn to accept tooth brushing stress-free at any age. If you'd like to find out about typical breed traits and grooming needs beforehand, the HonestDog breed finder offers helpful guidance.

Keep the teething phase in mind

Between the third and sixth month of life, a young dog loses his 28 baby teeth while the 42 permanent teeth break through. During this phase the gums are often irritated, slightly red and sometimes bleed a little. If you scrub away with a brush in your dog's mouth at this stage, he'll associate tooth brushing with pain. Pause proper brushing on sore days during teething and limit yourself to a quick look inside. This daily look matters for spotting so-called retained baby teeth in good time: if a baby canine doesn't fall out even though the permanent tooth is already growing in next to it, your vet needs to check it, because plaque settles extremely quickly in the narrow gap otherwise.

Common mistakes when brushing teeth — and what helps instead

Even with the best intentions, small mistakes often creep into daily dental care, causing your dog to turn his head away or the training to stall. If you know the typical stumbling blocks, you can easily avoid them.

• Mistake 1: Using human toothpaste or home remedies
  Human toothpaste – including children's toothpaste – is strictly off limits for dogs. Dogs can't spit after brushing and swallow the paste. Many human toothpastes contain fluoride, foaming surfactants (which irritate the stomach lining) or the sugar substitute xylitol (birch sugar), which in even the tiniest amounts causes a life-threatening drop in blood sugar and liver damage in dogs. Home remedies such as baking soda or salt also damage the tooth enamel and the stomach.
  What helps instead: Use only special dog toothpaste with an enzymatic or mildly abrasive action, or, if in doubt, brush with plain lukewarm water only.
• Mistake 2: Starting right at the front incisors
  Out of human habit, many owners put the toothbrush on the incisors head-on first. In dogs, though, the area directly under the nose is highly sensitive. Often the dog sneezes, finds the touch unpleasant and pulls his head back immediately.
  What helps instead: Always start at the side with the large canines and work your way back to the molars. The small incisors only get their turn at the very end, for a few seconds.
• Mistake 3: Trying to scrub off hard tartar
  When thick, yellowish-brown crusts are already sitting on the teeth, some owners reach for hard brushes or even metal tartar scrapers. But this can't remove tartar below the gum line; instead it causes painful injuries to the gums and fine scratches in the enamel, where new plaque sticks even faster.
  What helps instead: Hardened tartar belongs at the vet's. At home, brush only on clean teeth or after a professional dental cleaning to remove new soft plaque.
• Mistake 4: Persuading or holding your dog when he wriggles
  If your dog is clamped between your knees because you're in a hurry, it creates stress. The next time he sees the toothbrush, he'll hide under the table.
  What helps instead: Work with a cooperation signal. If your dog turns his head to the side, pause immediately for two seconds and wait calmly until he turns back. Short sessions of 20 seconds per side of the jaw, followed by a reward, get you to your goal faster than a forced show of strength.

When to get help: clear warning signs for the vet or a trainer

As the practising vet Ralph Rückert stresses in his professional articles, even the most conscientious home dental care has its anatomical limits: certain teeth – such as the back molars in the upper jaw – are hard to reach fully with a brush, and problems below the gum line often stay invisible to the naked eye. If a dog already has toothache, he'll resist any contact with the toothbrush – often suffering in silence, since dogs rarely show chronic mouth pain by yelping.

You should pause brushing straight away and see your vet soon if you notice any of the following warning signs:

• Strong, foul-smelling breath: A clear sign of bacterial decay and inflammation in the gum pockets.
• Red, swollen or bleeding gums: A red edge along the teeth or traces of blood on chew toys point to acute gingivitis or periodontitis.
• Yellowish-brown, hard crusts: Visible tartar, especially on the canines and back molars.
• Changed eating behaviour: Your dog suddenly chews on only one side of the jaw, drops hard dry food, eats hesitantly or swallows chunks whole without chewing.
• Defensive behaviour or face rubbing: Your dog paws at his muzzle, drools more or flinches when you touch his cheek.
• Broken, discoloured or wobbly teeth: Any loose tooth or tooth with a bluish-pink discolouration needs urgent examination by a veterinary dentist (including dental X-rays).

Important for veterinary treatment: a thorough dental cleaning and examination of the gum pockets is only possible in dogs under gentle anaesthesia. Veterinary professional associations and universities expressly advise against so-called “anaesthesia-free dental cleanings” (for example at dog groomers or with ultrasonic devices on a conscious animal), because they only cosmetically clean the visible tooth crowns, while the disease-causing bacteria remain beneath the gum line and the animal is put under considerable stress.

If your dog shows strong fear or aggression (such as growling, snapping or freezing) as soon as you approach his muzzle, even though his teeth have been confirmed healthy by a vet, bring in a qualified dog trainer who specialises in medical training. Together you can use targeted counter-conditioning and a cooperation signal (such as voluntarily resting his chin on your hand) to create a safe setting in which your dog stays in control.

Frequently asked questions

How often should you brush a dog's teeth?

Vets recommend daily tooth brushing as the ideal. Since soft plaque hardens into solid tartar within about 48 to 72 hours due to the minerals in saliva, cleaning should take place at least three times a week to reliably interrupt this process. Brushing once a week usually isn't enough to prevent tartar.

When should you start brushing a dog's teeth?

You should begin the playful getting-used-to phase – briefly lifting the lips and touching the teeth with a finger – as early as puppyhood, from the 8th to 12th week of life. The actual daily brushing with a soft dog toothbrush ideally starts once teething is finished, from the sixth to seventh month. With adult dogs, you can begin training at any time.

Is brushing a dog's teeth really worthwhile – wolves don't brush either, do they?

Yes, brushing your dog's teeth is very worthwhile. The comparison with the wolf falls short for several reasons. For one, domestic dogs mostly eat finely minced canned or dry food instead of whole prey with fur, tendons and cartilage. For another, many dog breeds have shorter jaws and tighter gaps between the teeth than the wolf as a result of breeding. On top of that, domestic dogs live considerably longer – and even wild wolves often suffer from severe dental damage in old age.

Can I brush my dog's teeth with coconut oil or a finger brush?

A microfibre finger brush works very well for the first weeks of getting used to it, as well as for very small breeds, but it reaches the narrow gaps between the teeth a little less well than a soft brush. Coconut oil is often mentioned as a home remedy, but it has no abrasive action and can't dissolve plaque on its own. If your dog likes the taste, you can put a tiny bit of coconut oil on the brush as a reward – but what really cleans is always the mechanical abrasion from brushing.

What helps if my dog won't let me brush his teeth at all?

If your dog still won't tolerate a toothbrush in his mouth even with patient training, once toothache has been ruled out, you can use the finger brush or put a special dental care gel (for example enzyme-based or, after consulting your vet, chlorhexidine-based) into the cheek pouches at the side. Tested chews that encourage long chewing also help. In this case, be sure to plan regular dental check-ups at your vet's so tartar can be professionally removed in good time.

Good dental care takes a bit of patience at the start, but it pays off over many years with a pain-free, lively dog and far fewer dental treatments under anaesthesia.
