My little Ziva (7) has the tiniest little white teeth, one day we looked in there and she no longer had two of her bottom four front teeth! But with just brushing her teeth are beautiful, I think these two were just too small?
Abby(5) is a different story- her teeth are what the vet calls" genetically bad", we are dealing with loosened inflamed top teeth now, she is sure to lose them surgically.
. Her little bottom teeth are just disintegrating. Same food, same water, same brushing!
