When Lastar came over from Spain his teeth weren't in a good condition due to picking up bricks from under water etc, so they were chipped and had lot's of tartar in them. Within 3 weeks of being on Plaque Off he had pearly white teeth and still does 3 years later.
I have to admit I hardly do anything with my dogs, but they do have meat and bones etc. My nearly 14 year old still has a full set of teeth, yep they are waring down but they are still there!
