My cat's gums are red and swollen but the vet says its chronic?

my cat of age 5 recently started having red and swollen gums. i have consulted the vet pertaining the matter many times. the vet says its some form of chronic where the teeth will start biting on its gums. im terribly worried. my cat have gone through dental treatment but it continued a few weeks later. there is no tartar only red gums. now it refuses to eat. what should i do? other than keep going to the vet to get my cat an injection every month?
