I have bectaria in my teeth?

i have bectaria in my all teeth ,all my teeth are black ...........
how can bectaria go........which toothpaste is good ?

Your teeth should never be black...Eveyone has hundreds of different bacteria in their mouth, you need to floss and brush with toothpaste to get rid of it. You need to go to your dentist if your teeth are darkening though because it could be a sign that the nerves in your teeth are dying.
