Dental treats rely on chewing friction against tooth surfaces, and some contain ingredients that help reduce plaque. Brushing physically removes plaque with pet-specific toothpaste and a soft brush, covering the outer tooth surfaces. The two work on different principles, so they complement rather than replace each other.

Treats win on compliance and are easy for cats to accept, making them a daily supplement. Brushing is more direct, but needs desensitisation from kittenhood, and adult cats often take weeks to accept a routine.

The trade-off is effect against execution: treats offer limited mechanical cleaning, cannot replace brushing, and their calories count toward the daily total. Brushing covers the gumline and gaps better, but poor technique builds resistance and can irritate gums.

Run both: brushing as the base, treats as support, plus regular oral checks. Cats with tartar, bad breath or pain when eating need a veterinary exam, and whether scaling is needed is a professional judgement.
