What is a good type of store bought brand wet food for a mid-older kitty with a partially broken tooth?

He is a neutered male brown tabby whom we rescued from an abandonment situation and now adopted. When we first rescued him he was a little imiciated with mangled claws and a tooth that is partially broken off. The vet said he is between 6-8 years old. We currently feed him Whiskas seafood sensations but are going to switch him to a wet food because he has a little hard time chewing because of that tooth. He is going to get it totally removed. I'm the one who always feeds him so i kinda watch him when he eats, and alot of the time he drops pieces of food into his water bowl. Which is why i want to switch him to a wet food, but what is the best kind? Help is greatly appreciated! Thank you!
