My cat has a severe gum infection. What treatment does he need?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | 6 months and 17 days old

Hello, we have a young cat with a mouth infection on the right hand side, which i think is gingivitis or stomatitis. We noticed it about three weeks ago. I have attached some pictures of the affected area. Could you please advise on the severity of the condition and how we can treat him? He has been seen by a local vet and has received a course of oral antibiotics but the problem persists. Does he need to have his teeth cleaned and plaque removed? Thankyou for your advice.

This is a severe gum infection and may be due to infected teeth also. Kuchi needs to be anesthetized and have a dental cleaning done. I expect he will need several teeth extracted and additional antibiotics. Some cats with stomatitis respond to steroid injections with the antibiotics but often almost all of the teeth need to be removed due to the pain and infection. If it has not been done I recommend a feline leukemia and FIV test also as this problem is more common in infected cats. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Kuchi.
