Is feeding raw meat twice a week benefiting Lacey’s teeth??

I’ve been feeding Lacey raw meat about twice a week for almost the past month now..She seems like she’s starting to enjoy it & over the past two weeks I have been giving her some raw this past week I have noticed her teeth has been extremely white no matter what diet she ate…She is still getting mostly dry food and can food in addition to raw meat couple times a week..Prior to this,she would eat mostly dry food,can food and mostly cooked meat and she’d still get tarter build up…..Am considering instead of buying another bag of Nature’s Variety when she runs out we’ll get her a couple choices of nature’s variety frozen raw in addition to raw meat and see how that goes then go back to dry food(Nature’s Variety) depending how much she likes frozen raw.
I do try to stick natural,organic raw meat for her when I do give her raw meat…If it’s a small portion of cooked meat like a small amount from fast food or cooked meat that’s not too bad but if it is raw meat for her to have as a meal I am a lot more careful of the type we buy her.So far we’ve used is 50th state poultry & foster farms..It also depends what is on sale & what she seems to like…Next up for Lacey is to try eating chicken drumsticks with the bone!
