>Vet told me the same thing basically. Continue to feed wet food and he will live healthier for longer, just take care of the teeth as best as you can ongoing and pull them as

I like to offer dry food on the side. A premium/dry food is not 'bad' for cats, just has limitations in regard to hydration.

I suspect it's not so much that can food is bad for cats teeth, but the dry food helps clean the teeth via mechanical action. This is just speculation on my part, however, they have done studies that show the piercing of the kibble by the teeth removes biofilm/bacterial growth from the enamel.
