Daily brushing, a yearly check-up and the vet when needed: how to keep your cat's teeth healthy and get your cat used to brushing step by step.
A cat with bad breath, who eats more softly or suddenly leaves kibble behind: sometimes the teeth are the cause. Cats hide pain well, so gum disease often goes unnoticed for a long time. Below you can read what you can do at home, what only the vet can do, and how to get a cat used to brushing step by step.
You keep your cat's teeth healthy with daily brushing, a dental check at the vet and, if needed, a professional dental cleaning. Dental snacks, powders and gels can help, but they do not replace brushing. Tartar that is already firmly attached cannot be removed at home: the vet does this under anaesthetic.
A thin layer of bacteria, called plaque, forms on the teeth every day. If it is not removed, it hardens into tartar. The gums become irritated and inflamed, and at a later stage the jaw bone can also be affected. According to the WSAVA (the global veterinary association), dental disease is one of the most common health problems in cats.
Cats can also develop tooth resorption lesions: painful spots where tooth tissue is broken down. You usually cannot see them with the naked eye. The vet finds them with a dental examination and X-rays.
⚠️ Call the vet if you see blood from the mouth, a swollen head or cheek, or if your cat hardly eats for a day or two. Do not wait and see in that case.
Brushing is the best way to remove plaque before it turns into tartar. Always use toothpaste made for cats. Human toothpaste is not meant to be swallowed and can contain ingredients that are not suitable for animals.
Keep sessions short, stop before your cat protests and never force it. Daily is ideal, but a few times a week is better than nothing.
| Option | What it does | Watch out |
|---|---|---|
| Dental kibble and snacks | Chewing can partly reduce plaque mechanically | Count the calories; does not replace brushing |
| Dental powder over the food | Intended to help reduce plaque without brushing | A supplement, not a replacement |
| Gels and sprays | Manufacturers aim them at oral hygiene and fresh breath | Evidence differs per product |
| Chew toys | Enrichment | Little evidence of an effect on tartar |
💡 Look for the seal of the Veterinary Oral Health Council (VOHC) on products. It is given to products for which the manufacturer has shown, using a set protocol, that they reduce plaque or tartar.
Myth: feeding only dry food does not keep the teeth clean by itself. Ordinary kibble often breaks apart quickly and hardly reaches the gum line.
Have the teeth checked at least once a year, and more often for older cats. A thorough cleaning is done under anaesthetic, so that the vet can also look under the gum line and take X-rays if needed. The WSAVA advises against dental cleaning without anaesthetic, because the areas under the gum line cannot be properly assessed and treated that way.
Daily is ideal. If that is not possible, a few times a week is still better than not brushing.
The younger, the easier the getting used to it. With a kitten, start by touching the mouth and let it get used to this calmly.
No. Persistent bad breath can point to a dental problem or another condition. Have the vet take a look.
Every anaesthetic carries a small risk. The vet weighs this against the risks of untreated dental disease and can run tests beforehand, especially for older cats.
Healthy cat teeth start at home with a small, regular routine and end at the vet when needed. Start slowly, reward generously and ask your vet for advice if you are unsure.
