Brushing a cat's teeth is likely to be the single most effective way to reduce dental plaque and maintain long-term oral health. Like humans, brushing will not only prevent plaque and tartar formation; it will also promote healthy gums and reduce bad breath. Daily brushing is ideal, if it is possible for your cat.
Some cats are prone to dental disease, due to many factors including genetics, diet and their immune status. Rigorous home care or, in severe cases, multiple teeth extractions may be needed to help these cats.
