How to Remove and Prevent Plaque and Tartar on Cat Teeth

June 10, 2026 · 4 min read

Plaque and tartar are the root of almost every feline dental problem. Understanding the difference explains exactly why daily brushing matters so much.

Plaque vs. tartar: what’s the difference?

Plaque is a soft, sticky film of bacteria that forms on the teeth every day. It is easy to remove by brushing. Tartar (also called calculus) is what plaque becomes when it is left alone — it mineralizes into a hard, yellow-brown crust within about 24 to 36 hours, and once it forms, brushing cannot remove it.

Can you remove tartar at home?

No — not safely. Hardened tartar bonds to the tooth and extends below the gum line. Trying to scrape it off at home can damage the enamel and gums and misses the part you cannot see. Only a veterinary dental cleaning under anesthesia removes tartar properly.

The key takeaway

You cannot remove tartar at home, but you can stop it from forming. Brushing removes plaque inside that 24–36 hour window, before it ever hardens.

How to prevent plaque and tartar

  • Brush daily — the single most effective step. See how to brush a cat’s teeth and how often to do it.
  • Use a cat-safe toothpaste with the right brush for a cat’s mouth.
  • Ask your vet about dental diets, treats, and water additives as supplements to brushing.
  • Schedule check-ups so any tartar is caught and cleaned early.
