Brushing Teeth

[Duffer]

Hi
I have a question about brushing teeth!
I thought i was doing it right, but Cava has some tartar on her teeth.:sl*p:
How often do i do it? How big of a brush do i use? Do i put anything on the brush ( have been using a liquid i bought in pet shop)

a liquid..?is it callled Doggy toothpaste,it usually comes in poultry flavour.
no real limit on how often you should brush thier teeth but the more you do it the better.
