Dog Dental Care: How to Brush Your Dog’s Teeth

Dental disease is one of the most common health problems vets see in adult dogs, yet it is also one of the easiest to prevent. Plaque builds up on teeth every day. If it is not removed, it hardens into tartar, irritates the gums and can lead to painful infections and tooth loss. Regular brushing at home is the single most effective way to keep your dog’s mouth healthy, and with a gentle approach most dogs learn to accept it.

Signs Your Dog May Have Dental Problems

Before you start a home routine, check your dog’s mouth. Lift the lips and look at the teeth and gums in good light. Book a vet check if you notice:

• Bad breath that does not go away.
• Yellow or brown crusty build-up near the gum line.
• Red, swollen or bleeding gums.
• Loose, broken or discoloured teeth.
• Dropping food, chewing on one side or pawing at the mouth.
• Reduced appetite, especially for hard food.

If there is already heavy tartar, brushing alone will not remove it. Your vet may recommend a professional dental clean under anaesthesia, after which home brushing helps keep the teeth clean.

What You Need

A Dog Toothbrush

Choose a soft-bristled brush sized for your dog’s mouth, or a finger brush for small dogs and beginners. A child’s soft toothbrush can work for small breeds.

Dog-Safe Toothpaste

Never use human toothpaste. Many contain fluoride levels and ingredients, such as xylitol, that are unsafe if swallowed, and dogs cannot spit. Pet toothpastes come in flavours dogs enjoy, such as poultry or malt, which makes brushing feel like a treat.

Patience and Treats

The first sessions are about building trust, not about perfect cleaning.

Step-by-Step Guide to Brushing

1. Pick a quiet time when your dog is relaxed, such as after a walk.
2. Let your dog taste the toothpaste from your finger. Praise and reward.
3. Touch the lips and teeth with your finger for a few seconds over several days.
4. Introduce the brush with a little toothpaste and let your dog lick it.
5. Lift the upper lip and brush the outer surfaces of a few front teeth in small circles, angling the bristles towards the gum line.
6. Gradually work back to the large cheek teeth and canines, which collect the most plaque.
7. Keep sessions short – 30 seconds is fine at first, building to about two minutes.
8. Finish with praise, play or a walk so your dog links brushing with good things.

Focus on the outside surfaces of the teeth. Most dogs’ tongues keep the inner surfaces relatively clean, and the outer surfaces are where plaque builds up fastest.

How Often Should You Brush?

Daily brushing is ideal because plaque begins to form within hours. If daily is not realistic, aim for at least several times a week. Consistency matters more than perfection; a quick daily brush is better than a long session once a month.

Helping a Reluctant Dog

Some dogs resist having their mouths handled. Slow down and break the process into tiny steps, rewarding each small success. Use a finger brush or a piece of gauze around your finger if a toothbrush feels too strange. Brush only a few teeth per session if needed. Avoid holding your dog down forcefully, which creates fear. If your dog growls or snaps, stop and ask your vet whether there is pain in the mouth, because sore teeth can make dogs defensive.

Other Tools That Support Dental Health

Brushing is the gold standard, but other products can help:

• Dental chews designed to reduce plaque, given as part of the daily calorie allowance.
• Dental diets with kibble shaped to scrape teeth as the dog chews.
• Water additives or gels recommended by your vet.
• Safe chew toys made of rubber or nylon.

Avoid very hard chews such as cooked bones, antlers or hooves, which can fracture teeth. A useful rule many vets mention: if you cannot press your thumbnail into a chew, it may be too hard. Our guide to best dog food choices explains how diet supports overall health.

Dental Care for Puppies

Starting early makes life much easier. Puppies lose their baby teeth and grow adult teeth during the first months of life. Gentle mouth handling during this time teaches them that brushing is normal. Use a very soft brush and keep sessions playful. Read our guide to training a puppy not to bite for help with mouthy puppies during the teething stage.

Small Breeds and Senior Dogs

Small and toy breeds often have crowded teeth, which trap more food and plaque, so they tend to need extra dental attention. Senior dogs may already have some gum disease, and their teeth can become sensitive. For both groups, regular vet dental checks – at least once a year – are important. Ask your vet to look at the teeth during every routine visit and note any changes on your dog’s health record.

Making Dental Care Part of Your Routine

Link brushing to an existing habit so you do not forget. Many owners brush their dog’s teeth right after their own evening routine, or straight after the last walk of the day. Keep the toothbrush and paste in the same visible spot, and reward your dog with a favourite game afterwards. Within a few weeks, many dogs start to come running when they see the brush.

FAQ

Can I use human toothpaste for my dog?

No. Human toothpaste can contain ingredients that are harmful if swallowed, and dogs cannot spit it out. Always use toothpaste made for dogs.

Do dental chews replace brushing?

Dental chews can help reduce plaque, but they do not clean as thoroughly as brushing. Use them as an extra, not a replacement.

Why does my dog’s breath smell so bad?

Persistent bad breath is often a sign of plaque, tartar or gum disease. It can also be linked to other health issues, so ask your vet if it continues.

How do I know if my dog needs a professional dental cleaning?

Visible tartar, red or bleeding gums, loose teeth or mouth pain are signs your dog may need a vet dental assessment and cleaning.
