Cute pics! I have seen those toys but Graham just dosen't chew much. He hardly uses the stuff that I do get him. As for teeth cleaning, I do brush Graham's teeth every other day or at least twice a week, but for a perfect cleaning what I use is a raw beef bone from the deli or the butcher shop. If it's kept raw it's soft enough to chew, and it does not splinter. It takes hours of constant chewing (that's the only thing he'll REALLY chew on) and his teeth end up as white as a puppies' teeth.
