What is Gum Disease in Cats

Gum disease, also known as periodontal disease, is a common condition in cats. It's primarily caused by bacterial plaque buildup, leading to more severe types of inflammation (Gingivitis) and/or the destruction of the tissues and bone that support the teeth, leading to tooth mobility and eventual loss (Periodontitis).    

Several factors can cause gum disease in cats:  

  • Congenital factors  

  • Diet and lack of oral hygiene

Treatment gum disease in cats

  • A dental scale and polish under general anaesthetic to remove plaque and tartar build-up   

  • Tooth removal, if severe dental disease is discovered  

Preventing gum disease in cats

Regular tooth brushing with safe cat’s toothpaste is the best way to keep your cat’s teeth and mouth healthy: 

  • Use a safe cat toothpaste  

  • Get your cat used to the taste of the toothpaste first for him/her to lick it and then on the brush to be licked off follow by reward  

  • Stretch your cat's lips far enough to insert the brush gently between the lips and gums making small, circular motions on the outer surfaces of the teeth  

  • Stop if your cat is sore or any signs of bleeding and contact your vet  

  • Cat’s friendly dental mouth wash and or dental treats  

  • Dental diet  

Outlook

The outlook for cats with gum disease varies depending on the stage and type of disease. The early stage (gingivitis) is often reversible with proper treatment and home care. However, if left untreated, it can progress to a more advanced stage of the disease, which is very difficult to resolve and can lead to tooth loss. Early detection and treatment are crucial for a positive outcome.
