Wet food doesn't destroy your cat's teeth and isn't bad for her health. Domestic cats naturally eat soft food anyway - mice, birds, fish - and their teeth don't get damaged from it. Dry food does help reduce plaque buildup a bit through mechanical friction, but it's not critical if you regularly brush her teeth or just keep an eye on their condition.
The real issue is something else: she's gotten used to wet food - that's it. Cats are picky eaters, and retraining an adult cat to a new texture is tough, sometimes impossible. You can try soaking dry food in water or broth to soften it and gradually get her used to it again, but if your cat absolutely refuses and the wet food of the same brand works for her - just stick with wet food. It's the same formula anyway.
The only thing you should pay attention to: watch her weight (wet food is more calorie-dense per gram) and clean her bowls after eating so odors don't build up. If she starts having dental problems (bad breath, plaque buildup, refusing to eat) - take her to the vet right away, but overall she'll be fine on wet food.
