I agree with the previous review
It's been well documented in veterinary journals that the physical action of brushing the teeth and feeding dry food is the only way to reduce and prevent plaque and tartar.

Tartar
Sorry, if you want to keep tartar(calculus) away you have to wash the dog's teeth, just like your own. No other way to do it.
