Yes, RAW definitely helps with cleaner teeth. For example, I acquired a 13 month old dog about 11 days ago and her teeth looked like she has been fed big piles of shit since birth. 11 days later after eating RAW from the night she arrived her teeth look incredible. I wish I would have took before pics but I had no clue RAW would make this big of difference this quick. Chewing the meat and bones work wonders on dogs teeth. I thought this dogs teeth were stained unless I got them cleaned at the vet, which I was not going to do. Can't say how much I'm glad I made the switch to RAW feeding, only regret is not switching sooner!!
