Floss/brush/wash at night, nothing in the morning ( hate brushing right before eating/drinking), extra flossing as-needed. Most of my cavities have been inbetween my teeth due to food staying in there longer than it should, so I generally floss after each meal with the little pick flossers.

I have the situation pretty well under control now but unfortunately I wasn't very attentive as a young adult (like one brush every few days and no flossing...), so I have quite a few fillings.
