I'm not your vet, so I'm sharing this for informational purposes, but your vet seems to have the opposite opinion of most vets I've spoken with. I foster with a few different organizations, so I've spoken with quite a few vets.

I had originally been feeding my own cats mostly kibble, but their vet strongly encouraged me to transition them to at least 50% wet. They won't really touch the wet if they also have kibble available, so now they only get wet food in their dishes, and kibble is reserved for use as treats. My oldest had his annual exam a few weeks ago and the vet said his teeth look great.

Studies have shown that cats that eat primarily dry food may drink more water than cats that eat primarily wet food, but cats on a primarily wet food diet overall consume more water. This is particularly important for their kidney and urinary health.

Dry food also tends to be much higher in carbohydrates, and cats really don't need carbohydrates, like at all. They need lots of protein and some fat.
