How can I get my Puppy to eat his Dry Food?

When I got my puppy several months back, he had no teeth and could not chew his dry food, so I fed him some wet/canned food. Recently his teeth grew back and now he can chew the dry food, but he doesn't like it. I asked my mother about this and she said that its because i got him used to the canned food. I really want him to eat his dry food because its better for his teeth and is more nutritious. Any tips? Suggestions? Thanks :)
