Our Vet recommended BioDent tablets for our mini dachschund three years ago following the removal of several teeth. Although two more teeth have been lost since then, it does seem as though we may be getting a handle on things. We were told that BioDent should help her rebuild jawbone, and we really don't have any way of determining if that is actually happening. But hope springs eternal and we keep giving her the tablets. She's 15 and she's in pretty good shape, other than her teeth.
