Good kibble, cat likes them, but who knows about their effect on teeth?
I cannot say if those have any effect on teeth hygiene as claimed, but my cat loves them because they are chunky! They feel a bit like a treat actually. List of ingredients is short which is always a good thing and there doesn't seem to be anything nasty in there. it also contains the same algae as Plaque-off, so if you believe Plaque-off works, you may want to try those!
