The N-Bone Pearly Whites are designed to be an easy and effective method of maintaining or promoting good oral hygiene between regularly scheduled veterinarian visits. The unique shape plus tricalcium phosphate effectively removes plaque and tartar buildup during chewing while calcium carbonate and vitamin D3 help build strong teeth and bones. Pearly Whites® typically last much longer than other oral hygiene or breath freshening bones.

It's hard to critique this product because I didn't know what to expect. I opened the package and this large bone was as hard as a rock. I gave it to Whitney to gnaw on and left for a short time. I came back in about an hour and it was totally gone [consumed].
Guess that means she really liked it for sure. I figured it would last somewhat longer but if she's happy, I'm happy. [:--)
