Teeth Staining?

Hi All,
I have been using Colloidal Silver as a mouth rinse for 5 mins 3 times a day for the past few weeks with great success for tooth pain. However I'm really scared it will stain my teeth. I have read online it can permanently stain your teeth black? Is this true? Is there anything I can do to prevent it from happening? Thank you ever so much
