Male cats are more prone to becoming "blocked" due to their relatively narrow urethras, but there are many males out there who never experience such problems. If your cat is turns out to be one that does experience problems, your vet can prescribe a food formulated specifically for urinary tract health.
Firstly, it is not true that dry food is better for their teeth. Cats either swallow the food whole or break larger pieces with the tip of the tooth which does nothing for the tartar line.
Neutered male cats are more prone to UTI's and if possible should be fed as little dry food as possible. Wet food is a much healthier way to feed your cats, be they male or female. The other poster mentioned that cats do not drink enough water as a rule. That is true so wet food helps hydrate our kitties.
