Dental care for cats

Dental disease is the most commonly overlooked health problem in cats. It's estimated that up to 70–80% of cats over 3 years old suffer from some form of dental disease – gum inflammation, tartar, periodontal disease or tooth resorption. Yet most owners have no idea, because cats are very good at hiding mouth pain and carry on eating despite considerable discomfort. Regular home dental care and preventive vet check-ups are the only reliable way to prevent these problems or catch them early.

Dental disease isn't just a matter of oral hygiene – it has a direct impact on a cat's overall health. Bacteria from infected gums and tartar enter the bloodstream and can damage the kidneys, heart and liver. A cat with chronic dental disease is constantly exposed to inflammation and pain, which lower its quality of life, weaken the immune system and speed up the ageing of the body.

The most common dental diseases in cats

• Plaque and tartar – plaque is a soft film of bacteria on the tooth surface that, without adequate care, mineralises into hard tartar. Tartar can't be removed with home care alone – it requires professional ultrasonic removal under general anaesthetic at the vet's. Regular home care slows plaque formation and delays the need for veterinary treatment.
• Gingivitis (gum inflammation) – the earliest stage of dental disease, showing up as redness and swelling of the gums along the tooth. At this stage the condition is still fully reversible with proper care. Ignored gingivitis progresses into periodontal disease.
• Periodontal disease – an advanced condition affecting the tissues around the tooth, including the ligaments and bone. It causes teeth to loosen and fall out, chronic pain and a risk of bacteria spreading through the body. In its advanced stage it's irreversible.
• Tooth resorption (FORL) – a condition unique to cats, in which the body gradually breaks down its own dental tissue. It affects up to 60% of cats over 6 years old and is very painful. The cause isn't fully understood. The only solution is extraction of the affected tooth.
• Stomatitis – severe inflammation of the entire oral lining causing extreme pain, refusal to eat and excessive drooling. In cats with chronic stomatitis, extraction of all the teeth is sometimes indicated as a last resort – toothless cats then live pain-free and eat commercial food without any problems.

Home dental care for cats

The gold standard of home dental care is regular brushing. Daily is ideal – but even brushing every other day or three times a week significantly reduces plaque build-up and slows the progression of dental disease. Brushing once a week or less has no proven positive effect on gum health.

• Toothbrushes for cats – available in two basic types. A classic small brush with soft bristles is more effective but requires greater cooperation from the cat. A finger brush is more intuitive for beginners and cats tend to tolerate it better. New owners can start simply by cleaning with gauze wrapped around a finger.
• Toothpaste for cats – never use human toothpaste. It contains fluoride and xylitol, which are toxic to cats and can cause serious poisoning if swallowed. Cat toothpaste is safe to swallow and comes in flavours cats find appealing – chicken, salmon, meat or cuttlefish.
• Dental gels and solutions – an alternative for cats that won't tolerate a brush. Applied directly to the teeth and gums with a finger or cotton bud. Enzymatic ingredients break down plaque chemically without mechanical brushing. Less effective than brushing, but considerably better than no care at all.
• Dental sprays – the simplest form of application, suitable for very resistant cats. Sprayed into the mouth, they act enzymatically on plaque. They require no handling of the cat's mouth, but are less effective than mechanical brushing.
• Dental treats and chew toys – mechanically clean the tooth surface during chewing and reduce plaque formation. They're a useful addition to a care routine and a great motivator for cats, but they can't replace brushing. Look for treats with VOHC (Veterinary Oral Health Council) certification, which guarantees proven effectiveness.
• Dental water additives and food supplements – products added to drinking water or food containing antimicrobial and enzymatic ingredients. Useful as an extra layer of care, or for cats for whom no other form of dental care is possible.

How to get a cat used to tooth brushing

Getting a cat used to tooth brushing requires a gradual approach, patience and positive association. Never start straight in with a brush – the cat will refuse and form a negative association that will be very hard to overcome.

• Weeks 1–2: Every day, put a small amount of cat toothpaste on your finger and let the cat lick it off as a treat. The only goal is a positive association with the paste.
• Weeks 3–4: Start gently massaging the gums and front teeth with a paste-covered finger. The cat should tolerate this contact without resistance.
• Weeks 5–6: Introduce a brush or finger brush – starting with just the front of the mouth, then gradually adding the other teeth.
• Always reward every successful brushing with a treat or play – positive association is key to the cat's long-term cooperation.
• If the cat still refuses brushing after several weeks of gradual habituation, discuss alternatives with your vet – a less effective option is still better than no care at all.

Signs of dental disease you shouldn't ignore:

• Bad breath – persistent unpleasant odour isn't normal and is one of the most common signs of dental disease or another health problem.
• Changes in eating – the cat chews only on one side, prefers soft food, eats more slowly or refuses dry kibble.
• Excessive drooling – especially if the saliva is discoloured or bloody.
• Pawing at the mouth – the cat is trying to ease pain or discomfort in its mouth.
• Red or bleeding gums – visible when checking the mouth, or as traces of blood in the food bowl.

Practical tips for your cat's dental care:

• Always brush your cat's teeth at the same time each day – cats are creatures of habit, and consistency reduces their resistance.
• Have your cat's teeth professionally checked by a vet at least once a year – a vet will spot problems that aren't visible to the naked eye.
• Get kittens used to dental care as early as possible – ideally from 8–12 weeks of age, when they adapt to new things most easily.
• After a professional dental clean at the vet's, resume home care straight away – without it, tartar starts forming again within a few weeks.

Healthy teeth are the foundation of a long, high-quality life for your cat. Five minutes of brushing a day is a small investment with a huge return – for your pet's health, comfort and lifespan.
