Science Diet Oral Care food question

I just looked at the ingredients for the Science Diet Oral Care Adult
dry food and it's basically the same as the adult Chicken & Rice. The
only difference that I saw was that the Oral Care has three extra
ingredients: powdered cellulose, vegetable oil, and calcium carbonate.
I read on a dental website that calcium carbonate is the cause of
tartar but can be used as an abrasive for cleaning teeth.

So does this food actually do any good? What makes it better/more
effective than the chicken & rice which also helps reduce tartar
build-up?

The nuggets are larger so the cat's teeth sink in farther when the cat bites
into them. Since cats don't masticate, dental dry food has little more
dental effect than regular dry food and the same disadvantages.

Your cat would probably be healthier on canned food and home dental cleaning
with Q-Tips dipped in saline or a damp gauze sponge wrapped around your
finger. Many people have also had success keeping their cats' teeth clean
with kitty toothbrushes.
