Christy, About a year ago, my vet recommended Oxyfresh Oral Hygiene Solution for my ferrets. It goes in their water, and has no detectable odor or taste. This stuff is wonderful! I use it for my cat and dog as well as the ferrets, and it has made a world of difference in my dog's breath - from really nasty to puppy breath! (I've since discovered that Oxyfresh is recommended by many dog breeders.) One of my ferrets has always suffered from excess tooth tartar and recurring gingivitis, but he now very old and fragile, so the anesthesia needed for a tooth scraping is no longer an option for him. Oxyfresh keeps his gingivitis under control - without it, I think his teeth would be a real problem for him. Oxyfresh makes a great ear cleaner as well. I haven't seen Oxyfresh products in any pet stores or pet product catalogs, but I order them online directly from the company: http://www.oxyfreshww.com/petcare/default.asp (I order the oral hygiene solution by the gallon; it's cheaper that way.) BTW, I'm not putting down Nolvadent Oral Solution, I just haven't tried it. I suspect it would be fine to use for your ferrets. I do use Nolvadent Otic Solution for my dog, and like it very much.
