How do you brush your dog's teeth?

More than eighty percent of dogs over three years old have tartar or gingivitis. Yet only a small minority of owners brush their dog's teeth. Five minutes a day prevents pain, bad breath, and expensive dental cleanings under anesthesia. This is how you do it.
📌 In brief
- Brush ideally every day, at least three times a week.
- Use only dog toothpaste — human toothpaste with xylitol or fluoride is toxic.
- Build it up in small steps over 1 to 2 weeks, always with a reward.
- Focus on the outside of the molars and canines: that's where most tartar accumulates.
- Bad breath, brown deposits, or bleeding gums? Have your dog checked by the vet.
Why is brushing dogs' teeth so important?
Because plaque hardens into tartar within 24 to 48 hours, and you can't remove tartar at home. Untreated gingivitis causes pain, tooth loss, and bacteria that burden the heart, liver, and kidneys via the bloodstream.
How often should you brush your dog's teeth?
Every day is ideal, three times a week is the absolute minimum. Because plaque hardens within two days, longer breaks will largely negate the effect.
Which toothpaste and brush should you use?
Always use toothpaste specifically made for dogs, usually with chicken or beef flavor. Human toothpaste contains fluoride and sometimes xylitol, which are toxic to dogs. For the brush, choose a soft dog toothbrush or a finger brush.
⚠️ Never human toothpaste
Xylitol causes a life-threatening drop in blood sugar and liver damage in dogs. Baking soda and human mouthwash are also not recommended.
Step-by-step plan: how to teach your dog to brush teeth
- Day 1-2: let your dog lick the toothpaste from your finger. Only that, with lots of praise.
- Day 3-4: gently lift the lip and touch the gums with your finger. Reward.
- Day 5-6: rub your finger or finger brush over the canines for a few seconds.
- Day 7-10: introduce the toothbrush on one side of the mouth. Keep it short.
- Afterwards: brush in small circles at a 45-degree angle, from back to front, about 30 seconds per side.
Choose a quiet moment, preferably after a walk when your dog is tired and relaxed. Always stop at a positive moment, even if you've only done half of it.
đź’ˇ Tip: You can largely skip the inside of the teeth. The tongue keeps that side fairly clean; most tartar is on the outside of the molars.
What if your dog really doesn't allow brushing?
Then you build up further on habituation and combine with alternatives. If it still doesn't work after weeks, ask your vet for advice — sometimes there is underlying pain.
| Method | Effect on plaque | When to use |
|---|---|---|
| Toothbrush + dog toothpaste | Very good | Daily, gold standard |
| Dental chew sticks | Moderate | As a supplement, watch calories |
| Enzymatic gel or spray | Moderate to good | For dogs that refuse brushing |
| Dental cleaning at the vet | Complete (including tartar) | 1 to 2 times per life or on advice |
How does teeth brushing fit into the rest of the care?
It works best as a fixed part of a grooming routine: brushing, checking ears, checking nails, and brushing teeth. A dog accustomed to being touched around the head and mouth will also tolerate brushing and nail clipping more easily. Read also how to care for your dog's ears and how to clip your dog's nails.

From what age do you brush a puppy's teeth?
From about eight weeks you can start with a finger brush. The younger you start, the more normal your dog will find it.
Do chew sticks help instead of brushing?
They reduce plaque a bit, but do not replace brushing. Consider them a supplement and count the calories.
Why does my dog's breath smell so bad?
Usually due to plaque, tartar, or gingivitis. If the odor persists despite brushing, have the teeth and organs checked.
Can you remove tartar yourself?
No. Scraping with an instrument damages the enamel and gums. Tartar should be removed by the vet.
How long should a brushing session last?
About 30 seconds per side, so a good minute in total. Regularity counts more than duration.
