Using an oral irrigation device like a Waterpik can get the particles between the teeth and in pockets under the gum line that brushing and flossing don't get. You'd be surprised, if you don't Waterpik regularly, at how many particles are dislodged into the sink even after brushing with an electric (Oral B) toothbrush. I find Flossing helps to scrape plaque off the tooth surface between teeth but isn't that great at particle removal. Remember that plaque is really a biofilm so by brushing and flossing you break up the biofilm. The oral irrigator removes the food particles (and blasts the bits of biofilm knocked loose,) from between the teeth. Follow up with some sort of mouthwash now that the biofilm is disturbed.
