Feline chronic gingivostomatitis (FCGS) causes severe chronic oral pain that significantly impairs quality of life. Understanding treatment options enables welfare-positive management of this challenging condition.
FCGS causes among the most severe chronic pain of any common companion animal condition. The oral inflammation affects every aspect of daily life: eating becomes painful, grooming is abandoned, and the persistent severe discomfort causes behavioural changes including withdrawal and reduced interaction. Cats with severe FCGS may stop eating almost entirely, losing significant body weight. Owner recognition of this suffering is often delayed because cats mask pain and reduced grooming may be attributed to normal ageing. When medical management fails, full-mouth or near-full-mouth extraction - though radical appearing - provides genuine welfare improvement for the majority of cats, who adapt remarkably well to toothless life and can eat moist food without difficulty. The welfare-positive decision-making framework for FCGS prioritises pain elimination over preservation of teeth that are driving immune pathology.
