The only thing that will help is a teeth cleaning at the vets which will cost lots of $$$$ OR start giving her raw meaty bones to gnaw on,such as ,marrow bones,chicken wings,pork/lamb ribs,beef soup bones etc etc. The choice is yours,a couple hundred dollars at the vets or a couple dollars a week on bones.
I have shih-tzu's who are prone to tartar build up,but their teeth are shiny white due to the bones i give them,they get one each per day of the recreational bones and a few chicken wing tips daily.
Can i ask what the difference between "dry"food and "kibble" is?I thought they were both the same thing
