Where tartar comes from and why it does not brush off
Tartar starts as soft plaque — a film of bacteria, saliva and food debris that forms on the teeth every day. While plaque is soft, a toothbrush removes it. If it is not removed, minerals from saliva are deposited in it, and within a few days the plaque starts to harden into tartar (calculus).
Tartar is rough and firmly bonded to the tooth. It forms not only on the visible part of the crown but also below the gum line. New plaque sticks even more easily to its rough surface, so tartar grows layer by layer while the gums beneath it become inflamed.
So even if you pick a piece of tartar off the crown, the main problem stays under the gums. What tartar looks like and why it matters is explained on the Tartar in dogs and cats page.
- Tartar on the crown — what owners can see.
- Plaque and tartar under the gum — the main source of inflammation.
- Periodontal pocket — a gap between the gum and the root.
- Bone around the root breaks down, and the tooth loses support.
Can tartar be removed from a dog’s teeth at home?
If we are talking about established tartar — no. And it is not that owners lack skill. The reasons are these:
- Tartar is hard and firmly bonded to the tooth. A brush, gauze or chews remove soft plaque, but not tartar.
- Much of the build-up is below the gum line. You cannot see it, and there is no safe way to reach it at home.
- Your dog will not lie still. One sudden movement and a sharp instrument cuts the gum, tongue or lip. You may also get bitten.
- After scaling, the teeth are polished. Without polishing, microscopic scratches remain on the enamel, and new plaque clings to them even faster.
Sometimes a piece of tartar breaks off on its own when the dog chews a treat or toy. That does not solve the problem: the deposits under the gums remain, and the inflammation continues.
What to remove dog tartar with: what helps and what is a myth
The internet is full of “recipes” for getting rid of tartar on a dog’s teeth. Most of them either do not work or do harm. Here is how they compare when laid out honestly:

How to recognise products that actually help
A useful guide is the VOHC (Veterinary Oral Health Council) seal. It is awarded to products that have shown in studies that they help slow the accumulation of plaque and/or tartar when used daily as directed.
Note the wording: “slow the accumulation”, not “remove existing tartar”. VOHC itself stresses that many pets, especially middle-aged and older ones, need periodic professional scaling. So chews or additives with the seal are a supplement to brushing, not a replacement for it.
How to start brushing your dog’s teeth so tartar does not come back
The main home tool against tartar is a toothbrush. It mechanically removes soft plaque before it has time to harden. Daily brushing is best. If that is not possible yet, start with a few times a week and gradually work up to every day.
Step-by-step guidance is in the articles How to brush your dog’s teeth properly and Home dental care for dogs and cats.
- 01
Touch
For a few days, simply touch your dog’s lips and muzzle, praise and reward.
- 02
Toothpaste on a finger
Let your dog lick pet toothpaste off your finger, then spread it with your finger over the outer surface of a few teeth.
- 03
Toothbrush
A soft brush angled towards the gum line, short circular movements. Start with the canines and the large back teeth — plaque builds up fastest there.
- 04
Habit
Every day at roughly the same time, in short sessions. Stop while your dog is still calm.
Your dog already has tartar: what to do
If yellow-brown tartar is already visible at the gum line, the plan looks like this:
Why it has to be under anaesthesia rather than a “quick clean without anaesthetic” is explained in Anaesthesia-free dog teeth cleaning: why it is risky. What professional cleaning includes is described on the Dog teeth cleaning page.
- 01
Examination and consultation
The vet assesses how much the gums have changed and how urgent it is. If you are not in Kyiv, you can start with an online consultation based on photos.
- 02
Pre-anaesthetic tests
Complete blood count and biochemistry, echocardiography, abdominal ultrasound. With concurrent conditions the list may be extended.
- 03
Professional cleaning as part of COHAT
Under inhalational anaesthesia: examination of every tooth, periodontal probing, dental radiographs, scaling above and below the gum line, polishing, clinically indicated treatment.
- 04
Home care
After the procedure — daily brushing so the tartar does not return. When to restart will be stated in your aftercare instructions.
When tartar is no longer just a cosmetic problem
Tartar itself does not hurt, and your dog may eat as usual. But it keeps bacteria against the gums, and periodontal disease often develops underneath. Signs of this stage include:
- bad breath that does not go away;
- a red line along the gums next to the teeth, bleeding;
- receding gums exposing part of the root;
- your dog takes food on one side, drops hard treats or shakes its head while eating;
- a loose tooth.
At this point home remedies only buy time. How deep the changes go can only be established under anaesthesia — with periodontal probing and dental radiographs. More in the article What periodontal disease in dogs is.
How much an examination and professional cleaning cost
You can start with an examination and consultation at the clinic or an online consultation. The cost of the basic COHAT protocol depends on the dog’s weight; anaesthesia is billed separately.
When to see a vet
- Swelling of the face, cheek or under an eye, pus or blood from the mouth — have your dog seen the same day.
- Your dog takes food on one side only, drops it from the mouth or has stopped chewing hard treats.
- The gums are red, swollen or bleeding — especially around teeth with tartar.
- Strong bad breath that does not go away.
- A tooth is loose, or the gums have receded and exposed the root.
- Tartar comes back quickly despite regular brushing.
What you can do at home
- Check the teeth in daylight: lift the lip and look at the canines and the large back teeth.
- If the gums are calm, start getting your dog used to a toothbrush and pet toothpaste — gradually, without force.
- As a supplement, choose chews or additives with the VOHC seal.
- Swap hard bones and antlers for safer chew toys.
- Photograph the teeth on both sides — this will be useful at the consultation.
What not to do at home
- Do not scrape tartar with metal instruments, a fingernail or a coin — it is easy to injure the gums and scratch the enamel.
- Do not use baking soda, hydrogen peroxide, vinegar or lemon juice.
- Do not brush your dog’s teeth with human toothpaste.
- Do not count on a gel or spray to “dissolve” tartar, and do not delay an examination because of it.
- Do not give painkillers from your own medicine cabinet: ibuprofen, paracetamol and other human medicines can be dangerous for dogs.
Frequently asked questions
There is no safe way: established tartar is hard, firmly attached to the tooth and extends under the gums. It is removed professionally, under anaesthesia, followed by polishing and an assessment of the gums. At home you can stop new tartar from forming by brushing daily with pet toothpaste.
Established tartar is removed with an ultrasonic scaler and hand instruments during a professional cleaning under anaesthesia. A toothbrush, chews and VOHC-accepted products help slow down the build-up of new plaque and tartar, but they do not remove existing tartar.
No. Gels and sprays can supplement home care and temporarily reduce bacteria, but they do not remove established tartar, especially under the gums. If tartar is already there, a professional cleaning is needed.
Better not. Baking soda is abrasive and high in sodium, while hydrogen peroxide irritates the gums and mucosa and can cause vomiting if swallowed. Neither of them dissolves tartar.
Book an examination and consultation: the vet will assess the gums and tell you how urgent it is. If a professional cleaning is needed, it is done as part of COHAT under anaesthesia after pre-anaesthetic tests. After the procedure, daily brushing at home helps keep the tartar from coming back.
