How to Brush Your Cat's Teeth (and Why It Matters More Than You Think)

In this guide

Dental disease is one of the most common, and most commonly ignored, health issues in adult cats. By around age three or four, a large proportion of cats show some degree of dental disease, and left unmanaged, it does not stay confined to the mouth, poor dental health has been linked to broader issues affecting the kidneys, liver, and heart over time.

Getting started without a fight

Do not begin with a toothbrush on day one. Start by simply touching your cat's face and gently lifting the lip for a few seconds, followed immediately by a treat, over several short sessions until this becomes unremarkable to your cat. Only once this is comfortable should a small amount of cat-specific toothpaste be introduced on a fingertip, letting your cat taste and get used to the flavour before any brush is involved at all.

The actual brushing

• Use a toothbrush designed for cats, either a small soft-bristled brush or a finger brush, never a human toothbrush, which is too large and too firm.
• Use only cat-specific enzymatic toothpaste; human toothpaste often contains ingredients that are genuinely unsafe for cats and should never be used.
• Focus on the outer surfaces of the teeth, working along the gumline in small circular motions, since a cat's tongue does most of the work on the inner surfaces naturally.
• Keep early sessions to just a few seconds on one or two teeth, gradually building towards the full mouth over several weeks rather than rushing.

How often is actually needed

Daily brushing is the gold standard, since plaque begins hardening into much harder to remove tartar within one to two days. If daily is not realistic, aiming for at least two to three times a week still meaningfully reduces plaque buildup compared to no brushing at all, though it will not fully match the results of a daily routine.

When brushing alone is not enough

Dental treats, water additives, and dental-formula kibble can all support oral health between brushings, though none of them replace brushing entirely. Most vets recommend an annual dental check as part of a general wellness visit, and by around three years old, many cats benefit from a professional cleaning under anaesthesia to address tartar that brushing alone cannot remove, particularly below the gumline where early disease often takes hold unnoticed.
