Why should you care for your cat’s teeth?

Feline oral hygiene is primarily about health, rather than appearance. Bacterial plaque forms on teeth every day. Untreated oral disease can cause chronic pain, eating difficulties and behavioural changes. The good news is that cats can gradually learn to accept home dental care. However, it is important to understand what brushing helps with and what it cannot cure.

The key point: Home brushing helps reduce bacterial plaque but does not remove established tartar, treat painful lesions or replace a veterinary dental examination.

1. How can you tell whether your cat’s teeth may hurt?

Cats can hide pain for a long time. A cat with severe oral disease may still approach its bowl and even eat, but differently from before. A good appetite should therefore not be taken as proof of healthy teeth.

Signs to watch for:

persistent bad breath;
red or bleeding gums, excessive drooling;
chewing on only one side, dropping food, chewing cautiously or avoiding harder pieces;
suddenly moving away from the bowl, reluctance to have the head touched, pawing at the mouth;
behavioural changes: withdrawal, irritability, reduced play and grooming.

An everyday example: a cat eagerly approaches its meal but jumps back after the first bite, shakes its head and tries to eat again. This may not be ‘fussy eating’. It can be a response to oral pain.

2. Which oral diseases occur in cats?

Gingivitis and periodontal disease

The tooth surface develops bacterial plaque, a layer of bacteria and other material. If it is not removed regularly, it can mineralise into tartar. Gingivitis may initially be reversible, but advanced periodontal disease also affects the structures that hold teeth in their sockets and can cause them to become loose. Visible tartar alone does not show the full extent of disease, as important changes may lie below the gumline.

Tooth resorption (TR, previously often called FORL)

Resorption is the gradual destruction of a tooth’s hard tissues. Lesions may begin in the root, so they are not always visible during a simple look inside the mouth. The condition can be very painful, and dental X-rays are needed for accurate diagnosis and treatment planning. There is no known effective way to prevent resorption through brushing alone.

Feline chronic gingivostomatitis (FCGS)

This is a severe, often very painful inflammatory condition in which lesions may extend well beyond the gums. A cat may drool, struggle to eat, lose weight or avoid contact. It is not simply ‘tartar on the teeth’ and needs veterinary investigation and treatment. Do not try to brush painful, severely affected tissues against the cat’s resistance.

3. Why are Sphynx teeth often yellow-brown?

Many Sphynx cats do not have snow-white canine teeth. They may be yellowish, amber or even brown despite the absence of oral disease symptoms. This characteristic finding has also been described in veterinary literature.

One reason is sebum, the natural secretion of the skin’s sebaceous glands. Sphynx cats produce it despite lacking a typical coat. During daily grooming, the secretion comes into contact with the teeth and may gradually leave surface staining.

Feline canine teeth also have an interesting anatomical feature. Their outer surface, facing the lips and cheeks, has a vertical developmental groove, also known as a ‘blood groove’. It is thought that, when prey is caught, this groove may allow blood to drain from the bite and reduce suction between the canine tooth and the tissues, helping the predator withdraw the tooth quickly. It is a natural feature of feline canine anatomy, rather than a channel draining blood from inside the tooth.

Surface deposits may collect more readily in the groove, making a dark line on the canine more noticeable. In Sphynx cats, grooming adds further staining as sebum settles on the teeth.

Brown canine teeth in a Sphynx are not evidence that it received antibiotics as a kitten. Some tetracycline antibiotics can discolour developing teeth, but this differs from pigments being deposited on their surfaces. Colour alone cannot establish the cause of staining.

Important: surface staining is not the same as tartar. Red gums, bad breath, pain or a marked colour change in a single tooth require dental assessment. Not every dark spot is harmless.

4. What can and cannot be done at home?

Daily brushing is the most effective way to mechanically reduce plaque at home. Gentle cleaning of the outer tooth surfaces, particularly along the gumline, matters most. There is no need to force the mouth open. A few accepted strokes performed regularly are better than one long session that puts the cat off.

Home care does not replace professional treatment. Tartar, painful periodontal pockets and root lesions need veterinary examination. A full dental assessment, cleaning below the gumline and dental X-rays are performed under appropriately managed general anaesthesia. Scraping visible tartar off an awake cat’s teeth is not equivalent to dental treatment and can cause stress, injury and missed disease.

5. What do you need to introduce toothbrushing?

A small, soft toothbrush, designed for cats or with a very small head.
Animal toothpaste that is safe to swallow. Human toothpaste is unsuitable for cats.
A favourite treat to reward calm cooperation.
A soft towel only if the cat likes being gently wrapped. It is not intended for forceful restraint.

Do not start brushing if your cat is clearly in pain, has bleeding gums or reacts strongly to its mouth being touched. A dental examination is needed first.

6. How do you teach a cat to accept brushing? Four stages

Stage 1. Becoming comfortable with touch

Choose a calm moment. Gently touch the cheek and lift the lip for a second, then reward the cat. Do not force the mouth open. Repeat brief attempts until the cat stays relaxed.

Stage 2. Getting to know toothpaste

Let your cat lick a little animal toothpaste. Do not rub it into the teeth straight away. At this stage, you are building a pleasant association with the product’s smell and taste.

Stage 3. First brush strokes

Show the brush, briefly touch the outer surface of one or two teeth and finish the attempt. Gradually progress to gentle strokes near the gumline. If your cat moves its head away or stiffens, return to an easier stage.

Stage 4. A calm routine

Aim for daily tooth cleaning. You do not need to complete the entire procedure in one session immediately. Consistency, willing acceptance and freedom from pain matter more than a perfect result on day one.

7. Enzymatic toothpaste, gauze, dental foods and treats

An enzymatic toothpaste or gel for cats can be a useful addition to oral care. If the cat accepts handling, gently spread the product over the outer tooth surfaces according to the manufacturer’s instructions. Soft gauze can also help with familiarisation, but gel without brushing does not provide the same mechanical plaque removal.

Ordinary dry food does not act like a toothbrush. Specially formulated dental foods and products are available whose effects on plaque or tartar have been evaluated. A useful selection criterion is the VOHC seal, but check whether the product has demonstrated an effect against plaque, tartar or both.

Do not use bones or very hard chews as a way to ‘clean teeth’. They can damage them.

Raw beef as an addition to dental care. Two or three times a week, a healthy cat can be offered a small portion of raw beef that has previously been frozen, thawed in the refrigerator and cut into cubes suitable for chewing. Firm, springy pieces encourage chewing, and contact between meat and tooth surfaces may help mechanically remove some soft deposits. However, this does not remove tartar or replace brushing and dental check-ups. Treat beef as an additional snack, rather than a replacement for complete food. To avoid upsetting the daily diet’s balance, the total amount of such additions should remain small, preferably below 10% of the cat’s daily dietary energy.

8. When is a veterinary visit necessary?

Arrange an oral examination if you notice bad breath, red gums, altered eating habits, drooling or reluctance to have the head touched. If your cat cannot eat, is clearly suffering, has heavy bleeding or a mouth injury, do not delay veterinary advice.

Ask for more than an assessment of the visible tooth crowns. Where periodontal disease or resorption is suspected, dental X-rays and assessment of every tooth are particularly important, because the crown may appear normal despite root lesions.

The conclusion: dental hygiene should be part of everyday cat care. The aim is not a white, attractive smile but reducing pain and disease that may otherwise go unnoticed for a long time.
