Signs of Dental Disease in Cats
June 10, 2026 · 4 min read
Because cats instinctively hide pain, dental disease is often advanced by the time owners notice. Knowing the early signs lets you act before your cat is suffering.
Early warning signs
- Bad breath — the earliest and most common sign. Learn more about cat bad breath and what it means.
- Red or swollen gums (gingivitis), especially along the gum line
- Yellow-brown tartar on the teeth
- Drooling, sometimes tinged with blood
Signs of more advanced disease
- Pawing at the mouth or rubbing the face
- Dropping food, chewing on one side, or eating less
- Weight loss from eating less
- Loose or missing teeth, or facial swelling
- Withdrawal or irritability from chronic pain
When to see a vet
Loose teeth, facial swelling, bleeding, or a cat that has stopped eating need veterinary attention promptly. A professional cleaning may be required to treat existing disease.
How to prevent it
The good news: most dental disease is preventable. Daily brushing removes plaque before it hardens, and annual dental check-ups catch problems early. Start with our guide to cat dental care and the step-by-step on brushing a cat’s teeth.

Watch for dropping food, chewing on one side, drooling, pawing at the mouth, eating less, or becoming withdrawn. Any of these warrant a vet visit.
