Feline Periodontitis — How It Differs from Gingivitis

Written and reviewed by the VetTree veterinary team · Last updated July 19, 2026 · Reference information

Feline periodontitis (gum disease) is a stage in which gingivitis progresses and even the bones and ligaments under the gums are damaged. Gingivitis can be reversed, but once it progresses to periodontitis, the damage is difficult to reverse. It is known that more than half of cats over the age of 3 have some form of dental disease, so it is important to manage them in the early stages (gingivitis).

Frequently asked questions

What is the difference between feline periodontitis and gingivitis?

Gingivitis is an early and reversible inflammation limited to the surface of the gums, while periodontitis is an advanced and irreversible stage in which the bone and ligaments under the gums are damaged. While gingivitis can be reversed with management, the damage to periodontitis is difficult to reverse.

Can periodontitis be treated?

Existing bone and ligament damage is difficult to reverse, but professional scaling, periodontal treatment, and home care can help manage progression. Severe cases may require extraction, so a veterinary exam is necessary.

Can cat gum disease be prevented?

Daily toothbrushing and regular exams can control plaque and identify gingivitis before it progresses to periodontitis.
