Dental disease affects approximately 70% of cats over the age of three. It is among the most common health issues in domestic cats and among the most consistently underaddressed by owners. It's also the starting point for problems that extend well beyond the mouth — bacteria from periodontal disease enter the bloodstream and connect to kidney, heart, and liver disease.
None of this is catastrophic if you catch it early. Most of it is preventable.
What you're dealing with
Plaque forms on teeth within hours of eating. Without removal, it mineralises into tartar within days. Tartar creates pockets between tooth and gum where bacteria accumulate. Left alone, this progresses to gingivitis, then periodontitis, then tooth resorption, bone loss, and pain that your cat will not tell you about directly but will express through reluctance to eat hard food, pawing at the mouth, or simply reduced food intake.
Professional dental cleaning under anaesthesia is available and effective. It is also expensive and carries the normal risks of general anaesthesia. Prevention is less expensive and carries no anaesthetic risk.
The gold standard: daily brushing
A cat-specific toothbrush (or a finger brush) and enzymatic cat toothpaste. Never human toothpaste — xylitol is toxic to cats, and fluoride at cat-consumption levels is problematic.
The introduction process takes weeks and is worth doing properly. Start by getting your cat comfortable with you handling her muzzle: brief, gentle, followed immediately by something positive. Then introduce the toothpaste as a taste experience — let her lick it off your finger. Then introduce the brush to the outside of the teeth, no brushing motion, just contact. Then brief brushing sessions, outer surfaces only initially (the tongue manages the inside surface adequately).
This works. It requires patience across roughly three to four weeks of consistent daily effort, and then it becomes a two-minute routine. Most cats tolerate it reasonably once habituated.
Alternatives if daily brushing isn't happening
Dental gels applied without brushing (enzyme-based, similar mechanism to toothpaste, less mechanical benefit but better than nothing). Water additives — ask your vet for specific product recommendations; the market ranges from well-evidenced to marketing theatre. Dental treats with the VOHC (Veterinary Oral Health Council) seal — the seal means the product has been independently tested. Without the seal, the claim is unverified.
Dental biscuits included in standard dry food have limited evidence. The texture sometimes helps; the formulation usually doesn't.
The annual vet check includes this
Ask your vet to assess dental health at every annual visit. They'll score gingivitis, identify early tartar accumulation, and tell you when a professional clean is warranted. Catching it at Stage 1 or 2 costs significantly less — financially and in terms of anaesthetic exposure — than waiting until Stage 3 or 4.
What good dental health looks like
Pink, firm gums. White or very slightly yellowed teeth (perfectly white is rare in adult cats). No visible tartar on the back teeth. No odour beyond normal breath. No reluctance to eat or chew. No pawing at the face.
If the gums are red along the tooth line, there's active gingivitis. That warrants a vet conversation.
Two minutes, daily. The maths on prevention, here as elsewhere, is not subtle.
