How do I keep plaque off my teeth?

I don’t have an exact answer to that, but I could give some general tips on oral hygiene.  The plaque buildup on your teeth is the result of the bacteria and food particles that sit on your teeth.  You can combat this with mechanical or chemical brushing and flossing.  A more thorough description of these two methods and their alternatives is available at this link, and further options are available at this link.  There are also apps that can automatically identify the types of plaque you have and recommend a dental care routine.  Unfortunately, I don’t have access to any of these, so I’m just going to read the Wikipedia page on “dental flossing” to you, although I’m not really sure what its full value is.

I've never heard of chemical brushing.  What is that?

So the mechanical and chemical methods that you mentioned both involve a toothbrush.  The first of these, mechanical brushing, involves a toothbrush with nylon bristles and with a soft plastic head.  This kind of toothbrush is used for daily cleaning.  You should spend at least two minutes brushing every tooth and gums.  The usual brushing pattern is to start at the gum line and then work your way up and across to the other side of the teeth.  Then move on to the next teeth and repeat.  As a more in-depth and thorough cleaning, you should switch to brushing all the surfaces of the teeth with a softer, smaller toothbrush.
