They never used silver fluoride in toothpaste. They used sodium fluoride in toothpaste before tin fluoride, and the tin fluoride is, in fact, "new and improved" since it also kills the bacteria that causes gingivitis. You can get silver fluoride drops but it's pretty damaging shit for anything that isn't teeth.
