CDS for teeth

Hi
I'm new on this topic and sometimes it's very confusing for me, especially that my English is not perfect.
I wanted to find out how many drops of CDS should I use on glass of water for tooth brushing?
How long to brush them, how often for best result and if it's safe.
Big thanks in advance
A.
