How to Brush Your Cat's Teeth: A UK Step-by-Step Guide
Dental disease is one of the most common health problems in UK cats — the PDSA estimates that over 80 per cent of cats over three years old have some degree of dental disease. Daily toothbrushing is the single most effective preventive measure. Despite what many owners assume, most cats can be trained to accept it with a patient, gradual approach.
Key takeaways
- Daily brushing is the single most effective way to prevent dental disease in cats — even three to four times per week provides meaningful benefit.
- Introduce toothbrushing gradually over two to four weeks using enzymatic cat toothpaste and a finger brush before progressing to a toothbrush.
- Never use human toothpaste on cats — fluoride and flavouring agents are toxic to cats if swallowed.
Why Brushing Your Cat's Teeth Matters
Dental disease in cats begins with plaque — a bacterial film that accumulates on tooth surfaces after eating. Within 24–48 hours, plaque begins to mineralise into tartar (calculus), which cannot be removed by brushing and requires a professional dental descale under general anaesthetic. Tartar causes gingival inflammation (gingivitis), then periodontal disease — irreversible destruction of the bone and ligaments supporting the teeth.
Untreated dental disease is painful, can cause tooth root abscesses, and the chronic bacterial load may affect the kidneys, liver and heart through bacteraemia (bacteria entering the bloodstream). Professional dental treatment under anaesthetic costs £150–£400 or more and carries the risks of anaesthesia — all of which are significantly reduced with regular preventive brushing. Daily brushing is the gold standard, but even three to four times per week provides meaningful benefit.
Getting the Right Equipment
Use a toothpaste specifically formulated for cats — never human toothpaste, which contains fluoride and flavouring agents that are toxic to cats if swallowed. Enzymatic cat toothpaste, available from your vet or pet shops, comes in flavours that cats find palatable: poultry, fish, malt or beef are most popular. The enzymes help break down plaque even in areas the brush doesn't fully reach.
For the brush itself, options include: a soft-bristled finger brush (a rubber cap worn over the fingertip — good for starting out because the owner can feel what they are doing), a small-headed angled cat toothbrush, or a very soft child's toothbrush. Gauze wrapped around a finger is another commonly used option that is very gentle for initial introduction. VOHC-approved products (those carrying the Veterinary Oral Health Council seal) have evidence supporting their efficacy.
Step-by-Step Introduction
Never start by putting a toothbrush straight in your cat's mouth — this is the fastest route to creating a permanently resistant cat. Instead, follow a gradual desensitisation programme over two to four weeks:
Week 1: Simply let the cat lick a tiny amount of toothpaste from your finger. Do this once daily, always followed by praise or a treat. Week 2: Apply a small amount of toothpaste to a finger brush or gauze and gently rub along the outer surfaces of the upper cheek teeth for a few seconds. The upper back teeth (carnassial teeth) are where tartar accumulates most quickly. Week 3: Gradually increase the duration and the number of teeth reached. Week 4: Introduce the proper toothbrush if the cat is tolerating the finger brush, using the same short, positive sessions. The goal is brief, consistent, positive daily sessions — not a thorough scrub in one long, stressful attempt.
Technique and Alternatives
Focus on the outer (buccal) surfaces of the teeth — the tongue naturally keeps the inner surfaces cleaner, and trying to brush the inside is typically not tolerated by cats. Use small circular or back-and-forth motions along the gum line. You do not need to open the cat's mouth widely — gently lifting the lip is sufficient.
For cats that remain resistant despite gradual introduction, dental alternatives can reduce (though not eliminate) plaque accumulation: dental water additives (added to the water bowl), dental chews approved by the VOHC, dental-specific prescription diets (such as Hills t/d or Royal Canin Dental), and dental gels (applied to the teeth without brushing). These are all inferior to brushing but better than nothing. Regular professional descales under anaesthetic remain necessary for cats with established disease — discuss frequency with your vet based on your cat's individual dental health.
Find a Vet Near You
Your vet nurse can demonstrate brushing technique and advise on your cat's current dental health at a nurse clinic visit. Use CompareMyVet at app.comparemyvet.uk to compare local practices and their dental and nurse clinic prices.
Common questions
Start as young as possible — ideally from kittenhood, before permanent teeth come in at around four to six months. Young kittens are most receptive to new experiences. Adult cats can also be trained with patience, but the process typically takes a little longer.
Brushing removes plaque but not tartar (calculus) once it has formed. If your cat already has significant tartar, a professional dental descale under anaesthetic is needed first to remove it. After the dental, starting a brushing routine immediately maintains the clean teeth and slows future tartar formation significantly.
A professional dental scale and polish under anaesthetic for a cat typically costs £150–£400 at a UK practice depending on complexity. Extractions add to this. The cost varies between practices — using CompareMyVet to compare published dental prices in your area helps ensure you receive fair value.
