Barring any health issues that would require a special type of food, you can get away with a quality all life stages wet food. You would have to start feeding with the recommendations on the back of the can. Typically it seems the recommended feeding amount is inflated and way too much, especially for an elderly dog that likely isn't very active, but if the dog starts gaining too much weight, back off. If it seems they're getting too lean, add more food.
Also, ask the dog's fosters what and how much they feed him. That may be an even better place to start, as you don't want to upset his gut by switching to a new food cold turkey.
And of course, talk to the vet. Vets aren't necessarily nutritionists, so keep that in mind, but they might be able to give you some suggestions for toothless dogs.
