How to Brush a Dog's Teeth: A Step-by-Step UK Guide

Brushing your dog's teeth daily is the most effective thing you can do to prevent painful dental disease, and most dogs can learn to accept it with patience. Use a dog toothbrush and dog toothpaste, never the human kind, build up slowly over a couple of weeks, and aim for the outer surfaces of the teeth where plaque gathers most. Done little and often, it takes a couple of minutes and saves a lot of misery later.

Why it matters more than people think

Dental disease is one of the most common health problems in UK dogs, and by middle age a large proportion have some degree of it. Built-up plaque hardens into tartar, inflames the gums and eventually causes pain, tooth loss and infection that can affect the whole body. The bad breath owners notice is usually the first warning sign, not a normal doggy quirk.

The good news is that home brushing genuinely slows this down. It's cheap, it's quick, and it spares your dog the discomfort and the vet bills that come with advanced disease.

What you'll need

• A dog toothbrush, a finger brush, or a soft child's brush
• Dog toothpaste in a flavour your dog likes, such as poultry or beef
• Treats for rewarding calm behaviour
• A quiet spot and a few unhurried minutes

Human toothpaste is a firm no. It contains fluoride and sometimes xylitol, both of which are toxic to dogs when swallowed, and dogs can't spit it out.

The step-by-step routine

The secret is going slowly. Rushing creates a dog that dreads the brush, so spread these steps over one to two weeks.

• Days 1 to 2: Let your dog lick a little dog toothpaste off your finger so they learn it tastes good.
• Days 3 to 4: Gently lift the lip and rub a dab of paste along the gum line with your finger. Keep it short and reward calm.
• Days 5 to 6: Introduce the brush with paste on it, letting your dog lick it before any brushing.
• Day 7 onwards: Brush a few teeth at a time, focusing on the outer surfaces at a 45-degree angle to the gum line, using small circles.
• Building up: Add more teeth each session until you can do the whole mouth in a minute or two.

Stop while your dog is still relaxed, not when they've had enough. Ending on a good note is what makes tomorrow easier.

Concentrate on the cheek-facing surfaces, especially the big back teeth, as that's where plaque and tartar build up fastest. The inner surfaces matter less, since the tongue helps keep them cleaner.

What to do with a reluctant dog

If your dog clamps shut or backs away, slow right down rather than forcing it. Drop back a step, shorten the sessions, and use higher-value treats. Some dogs simply need weeks rather than days, and that's fine. Never pin a frightened dog down to brush, as you'll only deepen the fear.

Brushing also gives you a chance to spot trouble early: red or bleeding gums, a broken or wobbly tooth, lumps, or a foul smell all warrant a look from your vet, who may recommend a professional scale and polish under anaesthetic.

Brushing plus a backup plan

Daily brushing is the gold standard, but it works even better alongside other dental support. Dog dental chews help scrape away some plaque between brushes and keep dogs occupied, though they're a complement rather than a replacement for the brush. You'll find them and other oral-care kit in the health and grooming category.

If you're choosing chews, our best dental chews guide explains which actually earn their keep and which are just calories. And while you're sorting your dog's grooming routine, our guide on how to stop a dog shedding covers the brushing side of coat care too, so the whole routine hangs together. Combine daily tooth brushing, sensible chews and regular vet check-ups, and you'll keep your dog's mouth healthy for years.
